Online User Forum For technical questions regarding the Control System or the FTC SDK, please visit the FTC Technology forum: FTC Technology Forum Release Information Version 5.5 (20200824-090813) Version 5.5 requires Android Studio 4.0 or later. New features Adds support for calling custom Java classes from Blocks OpModes (fixes SkyStone issue #161). Classes must be in the org.firstinspires.ftc.teamcode package. Methods must be public static and have no more than 21 parameters. Parameters declared as OpMode, LinearOpMode, Telemetry, and HardwareMap are supported and the argument is provided automatically, regardless of the order of the parameters. On the block, the sockets for those parameters are automatically filled in. Parameters declared as char or java.lang.Character will accept any block that returns text and will only use the first character in the text. Parameters declared as boolean or java.lang.Boolean will accept any block that returns boolean. Parameters declared as byte, java.lang.Byte, short, java.lang.Short, int, java.lang.Integer, long, or java.lang.Long, will accept any block that returns a number and will round that value to the nearest whole number. Parameters declared as float, java.lang.Float, double, java.lang.Double will accept any block that returns a number. Adds telemetry API method for setting display format Classic Monospace HTML (certain tags only) Adds blocks support for switching cameras. Adds Blocks support for TensorFlow Object Detection with a custom model. Adds support for uploading a custom TensorFlow Object Detection model in the Manage page, which is especially useful for Blocks and OnBotJava users. Shows new Control Hub blink codes when the WiFi band is switched using the Control Hub's button (only possible on Control Hub OS 1.1.2) Adds new warnings which can be disabled in the Advanced RC Settings Mismatched app versions warning Unnecessary 2.4 GHz WiFi usage warning REV Hub is running outdated firmware (older than version 1.8.2) Adds support for Sony PS4 gamepad, and reworks how gamepads work on the Driver Station Removes preference which sets gamepad type based on driver position. Replaced with menu which allows specifying type for gamepads with unknown VID and PID Attempts to auto-detect gamepad type based on USB VID and PID If gamepad VID and PID is not known, use type specified by user for that VID and PID If gamepad VID and PID is not known AND the user has not specified a type for that VID and PID, an educated guess is made about how to map the gamepad Driver Station will now attempt to automatically recover from a gamepad disconnecting, and re-assign it to the position it was assigned to when it dropped If only one gamepad is assigned and it drops: it can be recovered If two gamepads are assigned, and have different VID/PID signatures, and only one drops: it will be recovered If two gamepads are assigned, and have different VID/PID signatures, and BOTH drop: both will be recovered If two gamepads are assigned, and have the same VID/PID signatures, and only one drops: it will be recovered If two gamepads are assigned, and have the same VID/PID signatures, and BOTH drop: neither will be recovered, because of the ambiguity of the gamepads when they re-appear on the USB bus. There is currently one known edge case: if there are two gamepads with the same VID/PID signature plugged in, but only one is assigned, and they BOTH drop, it's a 50-50 chance of which one will be chosen for automatic recovery to the assigned position: it is determined by whichever one is re-enumerated first by the USB bus controller. Adds landscape user interface to Driver Station New feature: practice timer with audio cues New feature (Control Hub only): wireless network connection strength indicator (0-5 bars) New feature (Control Hub only): tapping on the ping/channel display will switch to an alternate display showing radio RX dBm and link speed (tap again to switch back) The layout will NOT autorotate. You can switch the layout from the Driver Station's settings menu. Breaking changes Removes support for Android versions 4.4 through 5.1 (KitKat and Lollipop). The minSdkVersion is now 23. Removes the deprecated LinearOpMode methods waitOneFullHardwareCycle() and waitForNextHardwareCycle() Enhancements Handles RS485 address of Control Hub automatically The Control Hub is automatically given a reserved address Existing configuration files will continue to work All addresses in the range of 1-10 are still available for Expansion Hubs The Control Hub light will now normally be solid green, without blinking to indicate the address The Control Hub will not be shown on the Expansion Hub Address Change settings page Improves REV Hub firmware updater The user can now choose between all available firmware update files Version 1.8.2 of the REV Hub firmware is bundled into the Robot Controller app. Text was added to clarify that Expansion Hubs can only be updated via USB. Firmware update speed was reduced to improve reliability Allows REV Hub firmware to be updated directly from the Manage webpage Improves log viewer on Robot Controller Horizontal scrolling support (no longer word wrapped) Supports pinch-to-zoom Uses a monospaced font Error messages are highlighted New color scheme Attempts to force-stop a runaway/stuck OpMode without restarting the entire app Not all types of runaway conditions are stoppable, but if the user code attempts to talk to hardware during the runaway, the system should be able to capture it. Makes various tweaks to the Self Inspect screen Renames "OS version" entry to "Android version" Renames "WiFi Direct Name" to "WiFi Name" Adds Control Hub OS version, when viewing the report of a Control Hub Hides the airplane mode entry, when viewing the report of a Control Hub Removes check for ZTE Speed Channel Changer Shows firmware version for all Expansion and Control Hubs Reworks network settings portion of Manage page All network settings are now applied with a single click The WiFi Direct channel of phone-based Robot Controllers can now be changed from the Manage page WiFi channels are filtered by band (2.4 vs 5 GHz) and whether they overlap with other channels The current WiFi channel is pre-selected on phone-based Robot Controllers, and Control Hubs running OS 1.1.2 or later. On Control Hubs running OS 1.1.2 or later, you can choose to have the system automatically select a channel on the 5 GHz band Improves OnBotJava New light and dark themes replace the old themes (chaos, github, chrome,...) the new default theme is light and will be used when you first update to this version OnBotJava now has a tabbed editor Read-only offline mode Improves function of "exit" menu item on Robot Controller and Driver Station Now guaranteed to be fully stopped and unloaded from memory Shows a warning message if a LinearOpMode exists prematurely due to failure to monitor for the start condition Improves error message shown when the Driver Station and Robot Controller are incompatible with each other Driver Station OpMode Control Panel now disabled while a Restart Robot is in progress Disables advanced settings related to WiFi direct when the Robot Controller is a Control Hub. Tint phone battery icons on Driver Station when low/critical. Uses names "Control Hub Portal" and "Control Hub" (when appropriate) in new configuration files Improve I2C read performance Very large improvement on Control Hub; up to ~2x faster with small (e.g. 6 byte) reads Not as apparent on Expansion Hubs connected to a phone Update/refresh build infrastructure Update to 'androidx' support library from 'com.android.support:appcompat', which is end-of-life Update targetSdkVersion and compileSdkVersion to 28 Update Android Studio's Android plugin to latest Fix reported build timestamp in 'About' screen Add sample illustrating manual webcam use: ConceptWebcam Bug fixes Fixes SkyStone issue #248 Fixes SkyStone issue #232 and modifies bulk caching semantics to allow for cache-preserving MANUAL/AUTO transitions. Improves performance when REV 2M distance sensor is unplugged Improves readability of Toast messages on certain devices Allows a Driver Station to connect to a Robot Controller after another has disconnected Improves generation of fake serial numbers for UVC cameras which do not provide a real serial number Previously some devices would assign such cameras a serial of 0:0 and fail to open and start streaming Fixes ftc_app issue #638. Fixes a slew of bugs with the Vuforia camera monitor including: Fixes bug where preview could be displayed with a wonky aspect ratio Fixes bug where preview could be cut off in landscape Fixes bug where preview got totally messed up when rotating phone Fixes bug where crosshair could drift off target when using webcams Fixes issue in UVC driver on some devices (ftc_app 681) if streaming was started/stopped multiple times in a row Issue manifested as kernel panic on devices which do not have this kernel patch. On affected devices which do have the patch, the issue was manifest as simply a failure to start streaming. The Tech Team believes that the root cause of the issue is a bug in the Linux kernel XHCI driver. A workaround was implemented in the SDK UVC driver. Fixes bug in UVC driver where often half the frames from the camera would be dropped (e.g. only 15FPS delivered during a streaming session configured for 30FPS). Fixes issue where TensorFlow Object Detection would show results whose confidence was lower than the minimum confidence parameter. Fixes a potential exploitation issue of CVE-2019-11358 in OnBotJava Fixes changing the address of an Expansion Hub with additional Expansion Hubs connected to it Preserves the Control Hub's network connection when "Restart Robot" is selected Fixes issue where device scans would fail while the Robot was restarting Fix RenderScript usage Use androidx.renderscript variant: increased compatibility Use RenderScript in Java mode, not native: simplifies build Fixes webcam-frame-to-bitmap conversion problem: alpha channel wasn't being initialized, only R, G, & B Fixes possible arithmetic overflow in Deadline Fixes deadlock in Vuforia webcam support which could cause 5-second delays when stopping OpMode Version 5.4 (20200108-101156) Fixes SkyStone issue #88 Adds an inspection item that notes when a robot controller (Control Hub) is using the factory default password. Fixes SkyStone issue #61 Fixes SkyStone issue #142 Fixes ftc_app issue #417 by adding more current and voltage monitoring capabilities for REV Hubs. Fixes a crash sometimes caused by OnBotJava activity Improves OnBotJava autosave functionality ftc_app #738 Fixes system responsiveness issue when an Expansion Hub is disconnected Fixes issue where IMU initialization could prevent Op Modes from stopping Fixes issue where AndroidTextToSpeech.speak() would fail if it was called too early Adds telemetry.speak() methods and blocks, which cause the Driver Station (if also updated) to speak text Adds and improves Expansion Hub-related warnings Improves Expansion Hub low battery warning Displays the warning immediately after the hub reports it Specifies whether the condition is current or occurred temporarily during an OpMode run Displays which hubs reported low battery Displays warning when hub loses and regains power during an OpMode run Fixes the hub's LED pattern after this condition Displays warning when Expansion Hub is not responding to commands Specifies whether the condition is current or occurred temporarily during an OpMode run Clarifies warning when Expansion Hub is not present at startup Specifies that this condition requires a Robot Restart before the hub can be used. The hub light will now accurately reflect this state Improves logging and reduces log spam during these conditions Syncs the Control Hub time and timezone to a connected web browser programming the robot, if a Driver Station is not available. Adds bulk read functionality for REV Hubs A bulk caching mode must be set at the Hub level with LynxModule#setBulkCachingMode(). This applies to all relevant SDK hardware classes that reference that Hub. The following following Hub bulk caching modes are available: BulkCachingMode.OFF (default): All hardware calls operate as usual. Bulk data can read through LynxModule#getBulkData() and processed manually. BulkCachingMode.AUTO: Applicable hardware calls are served from a bulk read cache that is cleared/refreshed automatically to ensure identical commands don't hit the same cache. The cache can also be cleared manually with LynxModule#clearBulkCache(), although this is not recommended. (advanced users) BulkCachingMode.MANUAL: Same as BulkCachingMode.AUTO except the cache is never cleared automatically. To avoid getting stale data, the cache must be manually cleared at the beginning of each loop body or as the user deems appropriate. Removes PIDF Annotation values added in Rev 5.3 (to AndyMark, goBILDA and TETRIX motor configurations). The new motor types will still be available but their Default control behavior will revert back to Rev 5.2 Adds new ConceptMotorBulkRead sample Opmode to demonstrate and compare Motor Bulk-Read modes for reducing I/O latencies. Version 5.3 (20191004-112306) Fixes external USB/UVC webcam support Makes various bugfixes and improvements to Blocks page, including but not limited to: Many visual tweaks Browser zoom and window resize behave better Resizing the Java preview pane works better and more consistently across browsers The Java preview pane consistently gets scrollbars when needed The Java preview pane is hidden by default on phones Internet Explorer 11 should work Large dropdown lists display properly on lower res screens Disabled buttons are now visually identifiable as disabled A warning is shown if a user selects a TFOD sample, but their device is not compatible Warning messages in a Blocks op mode are now visible by default. Adds goBILDA 5201 and 5202 motors to Robot Configurator Adds PIDF Annotation values to AndyMark, goBILDA and TETRIX motor configurations. This has the effect of causing the RUN_USING_ENCODERS and RUN_TO_POSITION modes to use PIDF vs PID closed loop control on these motors. This should provide more responsive, yet stable, speed control. PIDF adds Feedforward control to the basic PID control loop. Feedforward is useful when controlling a motor's speed because it "anticipates" how much the control voltage must change to achieve a new speed set-point, rather than requiring the integrated error to change sufficiently. The PIDF values were chosen to provide responsive, yet stable, speed control on a lightly loaded motor. The more heavily a motor is loaded (drag or friction), the more noticable the PIDF improvement will be. Fixes startup crash on Android 10 Fixes ftc_app issue #712 (thanks to FROGbots-4634) Fixes ftc_app issue #542 Allows "A" and lowercase letters when naming device through RC and DS apps. Version 5.2 (20190905-083277) Fixes extra-wide margins on settings activities, and placement of the new configuration button Adds Skystone Vuforia image target data. Includes sample Skystone Vuforia Navigation op modes (Java). Includes sample Skystone Vuforia Navigation op modes (Blocks). Adds TensorFlow inference model (.tflite) for Skystone game elements. Includes sample Skystone TensorFlow op modes (Java). Includes sample Skystone TensorFlow op modes (Blocks). Removes older (season-specific) sample op modes. Includes 64-bit support (to comply with Google Play requirements). Protects against Stuck OpModes when a Restart Robot is requested. (Thanks to FROGbots-4634) (ftc_app issue #709) Blocks related changes: Fixes bug with blocks generated code when hardware device name is a java or javascript reserved word. Shows generated java code for blocks, even when hardware items are missing from the active configuration. Displays warning icon when outdated Vuforia and TensorFlow blocks are used (SkyStone issue #27) Version 5.1 (20190820-222104) Defines default PIDF parameters for the following motors: REV Core Hex Motor REV 20:1 HD Hex Motor REV 40:1 HD Hex Motor Adds back button when running on a device without a system back button (such as a Control Hub) Allows a REV Control Hub to update the firmware on a REV Expansion Hub via USB Fixes SkyStone issue #9 Fixes ftc_app issue #715 Prevents extra DS User clicks by filtering based on current state. Prevents incorrect DS UI state changes when receiving new OpMode list from RC Adds support for REV Color Sensor V3 Adds a manual-refresh DS Camera Stream for remotely viewing RC camera frames. To show the stream on the DS, initialize but do not run a stream-enabled opmode, select the Camera Stream option in the DS menu, and tap the image to refresh. This feature is automatically enabled when using Vuforia or TFOD—no additional RC configuration is required for typical use cases. To hide the stream, select the same menu item again. Note that gamepads are disabled and the selected opmode cannot be started while the stream is open as a safety precaution. To use custom streams, consult the API docs for CameraStreamServer#setSource and CameraStreamSource. Adds many Star Wars sounds to RobotController resources. Added SKYSTONE Sounds Chooser Sample Program. Switches out startup, connect chimes, and error/warning sounds for Star Wars sounds Updates OnBot Java to use a WebSocket for communication with the robot The OnBot Java page no longer has to do a full refresh when a user switches from editing one file to another Known issues: Camera Stream The Vuforia camera stream inherits the issues present in the phone preview (namely ftc_app issue #574). This problem does not affect the TFOD camera stream even though it receives frames from Vuforia. The orientation of the stream frames may not always match the phone preview. For now, these frames may be rotated manually via a custom CameraStreamSource if desired. OnBotJava Browser back button may not always work correctly It's possible for a build to be queued, but not started. The OnBot Java build console will display a warning if this occurs. A user might not realize they are editing a different file if the user inadvertently switches from one file to another since this switch is now seamless. The name of the currently open file is displayed in the browser tab. Version 5.0 (built on 19.06.14) Support for the REV Robotics Control Hub. Adds a Java preview pane to the Blocks editor. Adds a new offline export feature to the Blocks editor. Display wifi channel in Network circle on Driver Station. Adds calibration for Logitech C270 Updates build tooling and target SDK. Compliance with Google's permissions infrastructure (Required after build tooling update). Keep Alives to mitigate the Motorola wifi scanning problem. Telemetry substitute no longer necessary. Improves Vuforia error reporting. Fixes ftctechnh/ftc_app issues 621, 713. Miscellaneous bug fixes and improvements. Version 4.3 (built on 18.10.31) Includes missing TensorFlow-related libraries and files. Version 4.2 (built on 18.10.30) Includes fix to avoid deadlock situation with WatchdogMonitor which could result in USB communication errors. Comm error appeared to require that user disconnect USB cable and restart the Robot Controller app to recover. robotControllerLog.txt would have error messages that included the words "E RobotCore: lynx xmit lock: #### abandoning lock:" Includes fix to correctly list the parent module address for a REV Robotics Expansion Hub in a configuration (.xml) file. Bug in versions 4.0 and 4.1 would incorrect list the address module for a parent REV Robotics device as "1". If the parent module had a higher address value than the daisy-chained module, then this bug would prevent the Robot Controller from communicating with the downstream Expansion Hub. Added requirement for ACCESS_COARSE_LOCATION to allow a Driver Station running Android Oreo to scan for Wi-Fi Direct devices. Added google() repo to build.gradle because aapt2 must be downloaded from the google() repository beginning with version 3.2 of the Android Gradle Plugin. Important Note: Android Studio users will need to be connected to the Internet the first time build the ftc_app project. Internet connectivity is required for the first build so the appropriate files can be downloaded from the Google repository. Users should not need to be connected to the Internet for subsequent builds. This should also fix buid issue where Android Studio would complain that it "Could not find com.android.tools.lint:lint-gradle:26.1.4" (or similar). Added support for REV Spark Mini motor controller as part of the configuration menu for a servo/PWM port on the REV Expansion Hub. Provide examples for playing audio files in an Op Mode. Block Development Tool Changes Includes a fix for a problem with the Velocity blocks that were reported in the FTC Technology forum (Blocks Programming subforum). Change the "Save completed successfully." message to a white color so it will contrast with a green background. Fixed the "Download image" feature so it will work if there are text blocks in the op mode. Introduce support for Google's TensorFlow Lite technology for object detetion for 2018-2019 game. TensorFlow lite can recognize Gold Mineral and Silver Mineral from 2018-2019 game. Example Java and Block op modes are included to show how to determine the relative position of the gold block (left, center, right). Version 4.1 (released on 18.09.24) Changes include: Fix to prevent crash when deprecated configuration annotations are used. Change to allow FTC Robot Controller APK to be auto-updated using FIRST Global Control Hub update scripts. Removed samples for non supported / non legal hardware. Improvements to Telemetry.addData block with "text" socket. Updated Blocks sample op mode list to include Rover Ruckus Vuforia example. Update SDK library version number. Version 4.0 (released on 18.09.12) Changes include: Initial support for UVC compatible cameras If UVC camera has a unique serial number, RC will detect and enumerate by serial number. If UVC camera lacks a unique serial number, RC will only support one camera of that type connected. Calibration settings for a few cameras are included (see TeamCode/src/main/res/xml/teamwebcamcalibrations.xml for details). User can upload calibration files from Program and Manage web interface. UVC cameras seem to draw a fair amount of electrical current from the USB bus. This does not appear to present any problems for the REV Robotics Control Hub. This does seem to create stability problems when using some cameras with an Android phone-based Robot Controller. FTC Tech Team is investigating options to mitigate this issue with the phone-based Robot Controllers. Updated sample Vuforia Navigation and VuMark Op Modes to demonstrate how to use an internal phone-based camera and an external UVC webcam. Support for improved motor control. REV Robotics Expansion Hub firmware 1.8 and greater will support a feed forward mechanism for closed loop motor control. FTC SDK has been modified to support PIDF coefficients (proportional, integral, derivative, and feed forward). FTC Blocks development tool modified to include PIDF programming blocks. Deprecated older PID-related methods and variables. REV's 1.8.x PIDF-related changes provide a more linear and accurate way to control a motor. Wireless Added 5GHz support for wireless channel changing for those devices that support it. Tested with Moto G5 and E4 phones. Also tested with other (currently non-approved) phones such as Samsung Galaxy S8. Improved Expansion Hub firmware update support in Robot Controller app Changes to make the system more robust during the firmware update process (when performed through Robot Controller app). User no longer has to disconnect a downstream daisy-chained Expansion Hub when updating an Expansion Hub's firmware. If user is updating an Expansion Hub's firmware through a USB connection, he/she does not have to disconnect RS485 connection to other Expansion Hubs. The user still must use a USB connection to update an Expansion Hub's firmware. The user cannot update the Expansion Hub firmware for a downstream device that is daisy chained through an RS485 connection. If an Expansion Hub accidentally gets "bricked" the Robot Controller app is now more likely to recognize the Hub when it scans the USB bus. Robot Controller app should be able to detect an Expansion Hub, even if it accidentally was bricked in a previous update attempt. Robot Controller app should be able to install the firmware onto the Hub, even if if accidentally was bricked in a previous update attempt. Resiliency FTC software can detect and enable an FTDI reset feature that is available with REV Robotics v1.8 Expansion Hub firmware and greater. When enabled, the Expansion Hub can detect if it hasn't communicated with the Robot Controller over the FTDI (USB) connection. If the Hub hasn't heard from the Robot Controller in a while, it will reset the FTDI connection. This action helps system recover from some ESD-induced disruptions. Various fixes to improve reliability of FTC software. Blocks Fixed errors with string and list indices in blocks export to java. Support for USB connected UVC webcams. Refactored optimized Blocks Vuforia code to support Rover Ruckus image targets. Added programming blocks to support PIDF (proportional, integral, derivative and feed forward) motor control. Added formatting options (under Telemetry and Miscellaneous categories) so user can set how many decimal places to display a numerical value. Support to play audio files (which are uploaded through Blocks web interface) on Driver Station in addition to the Robot Controller. Fixed bug with Download Image of Blocks feature. Support for REV Robotics Blinkin LED Controller. Support for REV Robotics 2m Distance Sensor. Added support for a REV Touch Sensor (no longer have to configure as a generic digital device). Added blocks for DcMotorEx methods. These are enhanced methods that you can use when supported by the motor controller hardware. The REV Robotics Expansion Hub supports these enhanced methods. Enhanced methods include methods to get/set motor velocity (in encoder pulses per second), get/set PIDF coefficients, etc.. Modest Improvements in Logging Decrease frequency of battery checker voltage statements. Removed non-FTC related log statements (wherever possible). Introduced a "Match Logging" feature. Under "Settings" a user can enable/disable this feature (it's disabled by default). If enabled, user provides a "Match Number" through the Driver Station user interface (top of the screen). The Match Number is used to create a log file specifically with log statements from that particular Op Mode run. Match log files are stored in /sdcard/FIRST/matlogs on the Robot Controller. Once an op mode run is complete, the Match Number is cleared. This is a convenient way to create a separate match log with statements only related to a specific op mode run. New Devices Support for REV Robotics Blinkin LED Controller. Support for REV Robotics 2m Distance Sensor. Added configuration option for REV 20:1 HD Hex Motor. Added support for a REV Touch Sensor (no longer have to configure as a generic digital device). Miscellaneous Fixed some errors in the definitions for acceleration and velocity in our javadoc documentation. Added ability to play audio files on Driver Station When user is configuring an Expansion Hub, the LED on the Expansion Hub will change blink pattern (purple-cyan) to indicate which Hub is currently being configured. Renamed I2cSensorType to I2cDeviceType. Added an external sample Op Mode that demonstrates localization using 2018-2019 (Rover Ruckus presented by QualComm) Vuforia targets. Added an external sample Op Mode that demonstrates how to use the REV Robotics 2m Laser Distance Sensor. Added an external sample Op Mode that demonstrates how to use the REV Robotics Blinkin LED Controller. Re-categorized external Java sample Op Modes to "TeleOp" instead of "Autonomous". Known issues: Initial support for UVC compatible cameras UVC cameras seem to draw significant amount of current from the USB bus. This does not appear to present any problems for the REV Robotics Control Hub. This does seem to create stability problems when using some cameras with an Android phone-based Robot Controller. FTC Tech Team is investigating options to mitigate this issue with the phone-based Robot Controllers. There might be a possible deadlock which causes the RC to become unresponsive when using a UVC webcam with a Nougat Android Robot Controller. Wireless When user selects a wireless channel, this channel does not necessarily persist if the phone is power cycled. Tech Team is hoping to eventually address this issue in a future release. Issue has been present since apps were introduced (i.e., it is not new with the v4.0 release). Wireless channel is not currently displayed for WiFi Direct connections. Miscellaneous The blink indication feature that shows which Expansion Hub is currently being configured does not work for a newly created configuration file. User has to first save a newly created configuration file and then close and re-edit the file in order for blink indicator to work. Version 3.6 (built on 17.12.18) Changes include: Blocks Changes Uses updated Google Blockly software to allow users to edit their op modes on Apple iOS devices (including iPad and iPhone). Improvement in Blocks tool to handle corrupt op mode files. Autonomous op modes should no longer get switched back to tele-op after re-opening them to be edited. The system can now detect type mismatches during runtime and alert the user with a message on the Driver Station. Updated javadoc documentation for setPower() method to reflect correct range of values (-1 to +1). Modified VuforiaLocalizerImpl to allow for user rendering of frames Added a user-overrideable onRenderFrame() method which gets called by the class's renderFrame() method. Version 3.5 (built on 17.10.30) Changes with version 3.5 include: Introduced a fix to prevent random op mode stops, which can occur after the Robot Controller app has been paused and then resumed (for example, when a user temporarily turns off the display of the Robot Controller phone, and then turns the screen back on). Introduced a fix to prevent random op mode stops, which were previously caused by random peer disconnect events on the Driver Station. Fixes issue where log files would be closed on pause of the RC or DS, but not re-opened upon resume. Fixes issue with battery handler (voltage) start/stop race. Fixes issue where Android Studio generated op modes would disappear from available list in certain situations. Fixes problem where OnBot Java would not build on REV Robotics Control Hub. Fixes problem where OnBot Java would not build if the date and time on the Robot Controller device was "rewound" (set to an earlier date/time). Improved error message on OnBot Java that occurs when renaming a file fails. Removed unneeded resources from android.jar binaries used by OnBot Java to reduce final size of Robot Controller app. Added MR_ANALOG_TOUCH_SENSOR block to Blocks Programming Tool. Version 3.4 (built on 17.09.06) Changes with version 3.4 include: Added telemetry.update() statement for BlankLinearOpMode template. Renamed sample Block op modes to be more consistent with Java samples. Added some additional sample Block op modes. Reworded OnBot Java readme slightly. Version 3.3 (built on 17.09.04) This version of the software includes improves for the FTC Blocks Programming Tool and the OnBot Java Programming Tool. Changes with verion 3.3 include: Android Studio ftc_app project has been updated to use Gradle Plugin 2.3.3. Android Studio ftc_app project is already using gradle 3.5 distribution. Robot Controller log has been renamed to /sdcard/RobotControllerLog.txt (note that this change was actually introduced w/ v3.2). Improvements in I2C reliability. Optimized I2C read for REV Expansion Hub, with v1.7 firmware or greater. Updated all external/samples (available through OnBot and in Android project folder). Vuforia Added support for VuMarks that will be used for the 2017-2018 season game. Blocks Update to latest Google Blockly release. Sample op modes can be selected as a template when creating new op mode. Fixed bug where the blocks would disappear temporarily when mouse button is held down. Added blocks for Range.clip and Range.scale. User can now disable/enable Block op modes. Fix to prevent occasional Blocks deadlock. OnBot Java Significant improvements with autocomplete function for OnBot Java editor. Sample op modes can be selected as a template when creating new op mode. Fixes and changes to complete hardware setup feature. Updated (and more useful) onBot welcome message. Known issues: Android Studio After updating to the new v3.3 Android Studio project folder, if you get error messages indicating "InvalidVirtualFileAccessException" then you might need to do a File->Invalidate Caches / Restart to clear the error. OnBot Java Sometimes when you push the build button to build all op modes, the RC returns an error message that the build failed. If you press the build button a second time, the build typically suceeds. Version 3.2 (built on 17.08.02) This version of the software introduces the "OnBot Java" Development Tool. Similar to the FTC Blocks Development Tool, the FTC OnBot Java Development Tool allows a user to create, edit and build op modes dynamically using only a Javascript-enabled web browser. The OnBot Java Development Tool is an integrated development environment (IDE) that is served up by the Robot Controller. Op modes are created and edited using a Javascript-enabled browser (Google Chromse is recommended). Op modes are saved on the Robot Controller Android device directly. The OnBot Java Development Tool provides a Java programming environment that does NOT need Android Studio. Changes with version 3.2 include: Enhanced web-based development tools Introduction of OnBot Java Development Tool. Web-based programming and management features are "always on" (user no longer needs to put Robot Controller into programming mode). Web-based management interface (where user can change Robot Controller name and also easily download Robot Controller log file). OnBot Java, Blocks and Management features available from web based interface. Blocks Programming Development Tool: Changed "LynxI2cColorRangeSensor" block to "REV Color/range sensor" block. Fixed tooltip for ColorSensor.isLightOn block. Added blocks for ColorSensor.getNormalizedColors and LynxI2cColorRangeSensor.getNormalizedColors. Added example op modes for digital touch sensor and REV Robotics Color Distance sensor. User selectable color themes. Includes many minor enhancements and fixes (too numerous to list). Known issues: Auto complete function is incomplete and does not support the following (for now): Access via this keyword Access via super keyword Members of the super cloass, not overridden by the class Any methods provided in the current class Inner classes Can't handle casted objects Any objects coming from an parenthetically enclosed expression Version 3.10 (built on 17.05.09) This version of the software provides support for the REV Robotics Expansion Hub. This version also includes improvements in the USB communication layer in an effort to enhance system resiliency. If you were using a 2.x version of the software previously, updating to version 3.1 requires that you also update your Driver Station software in addition to updating the Robot Controller software. Also note that in version 3.10 software, the setMaxSpeed and getMaxSpeed methods are no longer available (not deprecated, they have been removed from the SDK). Also note that the the new 3.x software incorporates motor profiles that a user can select as he/she configures the robot. Changes include: Blocks changes Added VuforiaTrackableDefaultListener.getPose and Vuforia.trackPose blocks. Added optimized blocks support for Vuforia extended tracking. Added atan2 block to the math category. Added useCompetitionFieldTargetLocations parameter to Vuforia.initialize block. If set to false, the target locations are placed at (0,0,0) with target orientation as specified in https://github.com/gearsincorg/FTCVuforiaDemo/blob/master/Robot_Navigation.java tutorial op mode. Incorporates additional improvements to USB comm layer to improve system resiliency (to recover from a greater number of communication disruptions). Additional Notes Regarding Version 3.00 (built on 17.04.13) In addition to the release changes listed below (see section labeled "Version 3.00 (built on 17.04.013)"), version 3.00 has the following important changes: Version 3.00 software uses a new version of the FTC Robocol (robot protocol). If you upgrade to v3.0 on the Robot Controller and/or Android Studio side, you must also upgrade the Driver Station software to match the new Robocol. Version 3.00 software removes the setMaxSpeed and getMaxSpeed methods from the DcMotor class. If you have an op mode that formerly used these methods, you will need to remove the references/calls to these methods. Instead, v3.0 provides the max speed information through the use of motor profiles that are selected by the user during robot configuration. Version 3.00 software currently does not have a mechanism to disable extra i2c sensors. We hope to re-introduce this function with a release in the near future. Version 3.00 (built on 17.04.13) *** Use this version of the software at YOUR OWN RISK!!! *** This software is being released as an "alpha" version. Use this version at your own risk! This pre-release software contains SIGNIFICANT changes, including changes to the Wi-Fi Direct pairing mechanism, rewrites of the I2C sensor classes, changes to the USB/FTDI layer, and the introduction of support for the REV Robotics Expansion Hub and the REV Robotics color-range-light sensor. These changes were implemented to improve the reliability and resiliency of the FTC control system. Please note, however, that version 3.00 is considered "alpha" code. This code is being released so that the FIRST community will have an opportunity to test the new REV Expansion Hub electronics module when it becomes available in May. The developers do not recommend using this code for critical applications (i.e., competition use). *** Use this version of the software at YOUR OWN RISK!!! *** Changes include: Major rework of sensor-related infrastructure. Includes rewriting sensor classes to implement synchronous I2C communication. Fix to reset Autonomous timer back to 30 seconds. Implementation of specific motor profiles for approved 12V motors (includes Tetrix, AndyMark, Matrix and REV models). Modest improvements to enhance Wi-Fi P2P pairing.

Channel change is enabled in the FTC Robot Controller app for Moto G 2nd and 3rd Gen phones. Users can now use annotations to register/disable their Op Modes. Changes in the Android SDK, JDK and build tool requirements (minsdk=19, java 1.7, build tools 23.0.3). Standardized units in analog input. Cleaned up code for existing analog sensor classes. setChannelMode and getChannelMode were REMOVED from the DcMotorController class. This is important - we no longer set the motor modes through the motor controller. setMode and getMode were added to the DcMotor class. ContinuousRotationServo class has been added to the FTC SDK. Range.clip() method has been overloaded so it can support this operation for int, short and byte integers. Some changes have been made (new methods added) on how a user can access items from the hardware map. Users can now set the zero power behavior for a DC motor so that the motor will brake or float when power is zero. Prototype Blockly Programming Mode has been added to FTC Robot Controller. Users can place the Robot Controller into this mode, and then use a device (such as a laptop) that has a Javascript enabled browser to write Blockly-based Op Modes directly onto the Robot Controller. Users can now configure the robot remotely through the FTC Driver Station app. Android Studio project supports Android Studio 2.1.x and compile SDK Version 23 (Marshmallow). Vuforia Computer Vision SDK integrated into FTC SDK. Users can use sample vision targets to get localization information on a standard FTC field. Project structure has been reorganized so that there is now a TeamCode package that users can use to place their local/custom Op Modes into this package. Inspection function has been integrated into the FTC Robot Controller and Driver Station Apps (Thanks Team HazMat… 9277 & 10650!). Audio cues have been incorporated into FTC SDK. Swap mechanism added to FTC Robot Controller configuration activity. For example, if you have two motor controllers on a robot, and you misidentified them in your configuration file, you can use the Swap button to swap the devices within the configuration file (so you do not have to manually re-enter in the configuration info for the two devices). Fix mechanism added to all user to replace an electronic module easily. For example, suppose a servo controller dies on your robot. You replace the broken module with a new module, which has a different serial number from the original servo controller. You can use the Fix button to automatically reconfigure your configuration file to use the serial number of the new module. Improvements made to fix resiliency and responsiveness of the system. For LinearOpMode the user now must for a telemetry.update() to update the telemetry data on the driver station. This update() mechanism ensures that the driver station gets the updated data properly and at the same time. The Auto Configure function of the Robot Controller is now template based. If there is a commonly used robot configuration, a template can be created so that the Auto Configure mechanism can be used to quickly configure a robot of this type. The logic to detect a runaway op mode (both in the LinearOpMode and OpMode types) and to abort the run, then auto recover has been improved/implemented. Fix has been incorporated so that Logitech F310 gamepad mappings will be correct for Marshmallow users. Release 16.07.08 For the ftc_app project, the gradle files have been modified to support Android Studio 2.1.x. Release 16.03.30 For the MIT App Inventor, the design blocks have new icons that better represent the function of each design component. Some changes were made to the shutdown logic to ensure the robust shutdown of some of our USB services. A change was made to LinearOpMode so as to allow a given instance to be executed more than once, which is required for the App Inventor. Javadoc improved/updated. Release 16.03.09 Changes made to make the FTC SDK synchronous (significant change!) waitOneFullHardwareCycle() and waitForNextHardwareCycle() are no longer needed and have been deprecated. runOpMode() (for a LinearOpMode) is now decoupled from the system's hardware read/write thread. loop() (for an OpMode) is now decoupled from the system's hardware read/write thread. Methods are synchronous. For example, if you call setMode(DcMotorController.RunMode.RESET_ENCODERS) for a motor, the encoder is guaranteed to be reset when the method call is complete. For legacy module (NXT compatible), user no longer has to toggle between read and write modes when reading from or writing to a legacy device. Changes made to enhance reliability/robustness during ESD event. Changes made to make code thread safe. Debug keystore added so that user-generated robot controller APKs will all use the same signed key (to avoid conflicts if a team has multiple developer laptops for example). Firmware version information for Modern Robotics modules are now logged. Changes made to improve USB comm reliability and robustness. Added support for voltage indicator for legacy (NXT-compatible) motor controllers. Changes made to provide auto stop capabilities for op modes. A LinearOpMode class will stop when the statements in runOpMode() are complete. User does not have to push the stop button on the driver station. If an op mode is stopped by the driver station, but there is a run away/uninterruptible thread persisting, the app will log an error message then force itself to crash to stop the runaway thread. Driver Station UI modified to display lowest measured voltage below current voltage (12V battery). Driver Station UI modified to have color background for current voltage (green=good, yellow=caution, red=danger, extremely low voltage). javadoc improved (edits and additional classes). Added app build time to About activity for driver station and robot controller apps. Display local IP addresses on Driver Station About activity. Added I2cDeviceSynchImpl. Added I2cDeviceSync interface. Added seconds() and milliseconds() to ElapsedTime for clarity. Added getCallbackCount() to I2cDevice. Added missing clearI2cPortActionFlag. Added code to create log messages while waiting for LinearOpMode shutdown. Fix so Wifi Direct Config activity will no longer launch multiple times. Added the ability to specify an alternate i2c address in software for the Modern Robotics gyro. Release 16.02.09 Improved battery checker feature so that voltage values get refreshed regularly (every 250 msec) on Driver Station (DS) user interface. Improved software so that Robot Controller (RC) is much more resilient and “self-healing” to USB disconnects: If user attempts to start/restart RC with one or more module missing, it will display a warning but still start up. When running an op mode, if one or more modules gets disconnected, the RC & DS will display warnings,and robot will keep on working in spite of the missing module(s). If a disconnected module gets physically reconnected the RC will auto detect the module and the user will regain control of the recently connected module. Warning messages are more helpful (identifies the type of module that’s missing plus its USB serial number). Code changes to fix the null gamepad reference when users try to reference the gamepads in the init() portion of their op mode. NXT light sensor output is now properly scaled. Note that teams might have to readjust their light threshold values in their op modes. On DS user interface, gamepad icon for a driver will disappear if the matching gamepad is disconnected or if that gamepad gets designated as a different driver. Robot Protocol (ROBOCOL) version number info is displayed in About screen on RC and DS apps. Incorporated a display filter on pairing screen to filter out devices that don’t use the “-“ format. This filter can be turned off to show all WiFi Direct devices. Updated text in License file. Fixed formatting error in OpticalDistanceSensor.toString(). Fixed issue on with a blank (“”) device name that would disrupt WiFi Direct Pairing. Made a change so that the WiFi info and battery info can be displayed more quickly on the DS upon connecting to RC. Improved javadoc generation. Modified code to make it easier to support language localization in the future. Release 16.01.04 Updated compileSdkVersion for apps Prevent Wifi from entering power saving mode removed unused import from driver station Corrrected "Dead zone" joystick code. LED.getDeviceName and .getConnectionInfo() return null apps check for ROBOCOL_VERSION mismatch Fix for Telemetry also has off-by-one errors in its data string sizing / short size limitations error User telemetry output is sorted. added formatting variants to DbgLog and RobotLog APIs code modified to allow for a long list of op mode names. changes to improve thread safety of RobocolDatagramSocket Fix for "missing hardware leaves robot controller disconnected from driver station" error fix for "fast tapping of Init/Start causes problems" (toast is now only instantiated on UI thread). added some log statements for thread life cycle. moved gamepad reset logic inside of initActiveOpMode() for robustness changes made to mitigate risk of race conditions on public methods. changes to try and flag when WiFi Direct name contains non-printable characters. fix to correct race condition between .run() and .close() in ReadWriteRunnableStandard. updated FTDI driver made ReadWriteRunnableStanard interface public. fixed off-by-one errors in Command constructor moved specific hardware implmentations into their own package. moved specific gamepad implemnatations to the hardware library. changed LICENSE file to new BSD version. fixed race condition when shutting down Modern Robotics USB devices. methods in the ColorSensor classes have been synchronized. corrected isBusy() status to reflect end of motion. corrected "back" button keycode. the notSupported() method of the GyroSensor class was changed to protected (it should not be public). Release 15.11.04.001 Added Support for Modern Robotics Gyro. The GyroSensor class now supports the MR Gyro Sensor. Users can access heading data (about Z axis) Users can also access raw gyro data (X, Y, & Z axes). Example MRGyroTest.java op mode included. Improved error messages More descriptive error messages for exceptions in user code. Updated DcMotor API Enable read mode on new address in setI2cAddress Fix so that driver station app resets the gamepads when switching op modes. USB-related code changes to make USB comm more responsive and to display more explicit error messages. Fix so that USB will recover properly if the USB bus returns garbage data. Fix USB initializtion race condition. Better error reporting during FTDI open. More explicit messages during USB failures. Fixed bug so that USB device is closed if event loop teardown method was not called. Fixed timer UI issue Fixed duplicate name UI bug (Legacy Module configuration). Fixed race condition in EventLoopManager. Fix to keep references stable when updating gamepad. For legacy Matrix motor/servo controllers removed necessity of appending "Motor" and "Servo" to controller names. Updated HT color sensor driver to use constants from ModernRoboticsUsbLegacyModule class. Updated MR color sensor driver to use constants from ModernRoboticsUsbDeviceInterfaceModule class. Correctly handle I2C Address change in all color sensors Updated/cleaned up op modes. Updated comments in LinearI2cAddressChange.java example op mode. Replaced the calls to "setChannelMode" with "setMode" (to match the new of the DcMotor method). Removed K9AutoTime.java op mode. Added MRGyroTest.java op mode (demonstrates how to use MR Gyro Sensor). Added MRRGBExample.java op mode (demonstrates how to use MR Color Sensor). Added HTRGBExample.java op mode (demonstrates how to use HT legacy color sensor). Added MatrixControllerDemo.java (demonstrates how to use legacy Matrix controller). Updated javadoc documentation. Updated release .apk files for Robot Controller and Driver Station apps. Release 15.10.06.002 Added support for Legacy Matrix 9.6V motor/servo controller. Cleaned up build.gradle file. Minor UI and bug fixes for driver station and robot controller apps. Throws error if Ultrasonic sensor (NXT) is not configured for legacy module port 4 or 5. Release 15.08.03.001 New user interfaces for FTC Driver Station and FTC Robot Controller apps. An init() method is added to the OpMode class. For this release, init() is triggered right before the start() method. Eventually, the init() method will be triggered when the user presses an "INIT" button on driver station. The init() and loop() methods are now required (i.e., need to be overridden in the user's op mode). The start() and stop() methods are optional. A new LinearOpMode class is introduced. Teams can use the LinearOpMode mode to create a linear (not event driven) program model. Teams can use blocking statements like Thread.sleep() within a linear op mode. The API for the Legacy Module and Core Device Interface Module have been updated. Support for encoders with the Legacy Module is now working. The hardware loop has been updated for better performance.

 [](https://search.maven.org/search?q=g:net.openid%20appauth) [](http://javadoc.io/doc/net.openid/appauth) [](https://github.com/openid/AppAuth-Android/actions/workflows/build.yml) [](https://codecov.io/github/openid/AppAuth-Android?branch=master) AppAuth for Android is a client SDK for communicating with [OAuth 2.0](https://tools.ietf.org/html/rfc6749) and [OpenID Connect](http://openid.net/specs/openid-connect-core-1_0.html) providers. It strives to directly map the requests and responses of those specifications, while following the idiomatic style of the implementation language. In addition to mapping the raw protocol flows, convenience methods are available to assist with common tasks like performing an action with fresh tokens. The library follows the best practices set out in [RFC 8252 - OAuth 2.0 for Native Apps](https://tools.ietf.org/html/rfc8252), including using [Custom Tabs](https://developer.chrome.com/multidevice/android/customtabs) for authorization requests. For this reason, `WebView` is explicitly *not* supported due to usability and security reasons. The library also supports the [PKCE](https://tools.ietf.org/html/rfc7636) extension to OAuth which was created to secure authorization codes in public clients when custom URI scheme redirects are used. The library is friendly to other extensions (standard or otherwise) with the ability to handle additional parameters in all protocol requests and responses. A talk providing an overview of using the library for enterprise single sign-on (produced by Google) can be found here: [Enterprise SSO with Chrome Custom Tabs](https://www.youtube.com/watch?v=DdQTXrk6YTk). ## Download AppAuth for Android is available on [MavenCentral](https://search.maven.org/search?q=g:net.openid%20appauth) ```groovy implementation 'net.openid:appauth:<version>' ``` ## Requirements AppAuth supports Android API 16 (Jellybean) and above. Browsers which provide a custom tabs implementation are preferred by the library, but not required. Both Custom URI Schemes (all supported versions of Android) and App Links (Android M / API 23+) can be used with the library. In general, AppAuth can work with any Authorization Server (AS) that supports native apps as documented in [RFC 8252](https://tools.ietf.org/html/rfc8252), either through custom URI scheme redirects, or App Links. AS's that assume all clients are web-based or require clients to maintain confidentiality of the client secrets may not work well. ## Demo app A demo app is contained within this repository. For instructions on how to build and configure this app, see the [demo app readme](https://github.com/openid/AppAuth-Android/blob/master/app/README.md). ## Conceptual overview AppAuth encapsulates the authorization state of the user in the [net.openid.appauth.AuthState](https://github.com/openid/AppAuth-Android/blob/master/library/java/net/openid/appauth/AuthState.java) class, and communicates with an authorization server through the use of the [net.openid.appauth.AuthorizationService](https://github.com/openid/AppAuth-Android/blob/master/library/java/net/openid/appauth/AuthorizationService.java) class. AuthState is designed to be easily persistable as a JSON string, using the storage mechanism of your choice (e.g. [SharedPreferences](https://developer.android.com/training/basics/data-storage/shared-preferences.html), [sqlite](https://developer.android.com/training/basics/data-storage/databases.html), or even just [in a file](https://developer.android.com/training/basics/data-storage/files.html)). AppAuth provides data classes which are intended to model the OAuth2 specification as closely as possible; this provides the greatest flexibility in interacting with a wide variety of OAuth2 and OpenID Connect implementations. Authorizing the user occurs via the user's web browser, and the request is described using instances of [AuthorizationRequest](https://github.com/openid/AppAuth-Android/blob/master/library/java/net/openid/appauth/AuthorizationRequest.java). The request is dispatched using [performAuthorizationRequest()](https://github.com/openid/AppAuth-Android/blob/master/library/java/net/openid/appauth/AuthorizationService.java#L159) on an AuthorizationService instance, and the response (an [AuthorizationResponse](https://github.com/openid/AppAuth-Android/blob/master/library/java/net/openid/appauth/AuthorizationResponse.java) instance) will be dispatched to the activity of your choice, expressed via an Intent. Token requests, such as obtaining a new access token using a refresh token, follow a similar pattern: [TokenRequest](https://github.com/openid/AppAuth-Android/blob/master/library/java/net/openid/appauth/TokenRequest.java) instances are dispatched using [performTokenRequest()](https://github.com/openid/AppAuth-Android/blob/master/library/java/net/openid/appauth/AuthorizationService.java#L252) on an AuthorizationService instance, and a [TokenResponse](https://github.com/openid/AppAuth-Android/blob/master/library/java/net/openid/appauth/TokenResponse.java) instance is returned via a callback. Responses can be provided to the [update()](https://github.com/openid/AppAuth-Android/blob/master/library/java/net/openid/appauth/AuthState.java#L367) methods on AuthState in order to track and persist changes to the authorization state. Once in an authorized state, the [performActionWithFreshTokens()](https://github.com/openid/AppAuth-Android/blob/master/library/java/net/openid/appauth/AuthState.java#L449) method on AuthState can be used to automatically refresh access tokens as necessary before performing actions that require valid tokens. ## Implementing the authorization code flow It is recommended that native apps use the [authorization code](https://tools.ietf.org/html/rfc6749#section-1.3.1) flow with a public client to gain authorization to access user data. This has the primary advantage for native clients that the authorization flow, which must occur in a browser, only needs to be performed once. This flow is effectively composed of four stages: 1. Discovering or specifying the endpoints to interact with the provider. 2. Authorizing the user, via a browser, in order to obtain an authorization code. 3. Exchanging the authorization code with the authorization server, to obtain a refresh token and/or ID token. 4. Using access tokens derived from the refresh token to interact with a resource server for further access to user data. At each step of the process, an AuthState instance can (optionally) be updated with the result to help with tracking the state of the flow. ### Authorization service configuration First, AppAuth must be instructed how to interact with the authorization service. This can be done either by directly creating an [AuthorizationServiceConfiguration](https://github.com/openid/AppAuth-Android/blob/master/library/java/net/openid/appauth/AuthorizationServiceConfiguration.java#L102) instance, or by retrieving an OpenID Connect discovery document. Directly specifying an AuthorizationServiceConfiguration involves providing the URIs of the authorization endpoint and token endpoint, and optionally a dynamic client registration endpoint (see "Dynamic client registration" for more info): ```java AuthorizationServiceConfiguration serviceConfig = new AuthorizationServiceConfiguration( Uri.parse("https://idp.example.com/auth"), // authorization endpoint Uri.parse("https://idp.example.com/token")); // token endpoint ``` Where available, using an OpenID Connect discovery document is preferable: ```java AuthorizationServiceConfiguration.fetchFromIssuer( Uri.parse("https://idp.example.com"), new AuthorizationServiceConfiguration.RetrieveConfigurationCallback() { public void onFetchConfigurationCompleted( @Nullable AuthorizationServiceConfiguration serviceConfiguration, @Nullable AuthorizationException ex) { if (ex != null) { Log.e(TAG, "failed to fetch configuration"); return; } // use serviceConfiguration as needed } }); ``` This will attempt to download a discovery document from the standard location under this base URI, `https://idp.example.com/.well-known/openid-configuration`. If the discovery document for your IDP is in some other non-standard location, you can instead provide the full URI as follows: ```java AuthorizationServiceConfiguration.fetchFromUrl( Uri.parse("https://idp.example.com/exampletenant/openid-config"), new AuthorizationServiceConfiguration.RetrieveConfigurationCallback() { ... } }); ``` If desired, this configuration can be used to seed an AuthState instance, to persist the configuration easily: ```java AuthState authState = new AuthState(serviceConfig); ``` ### Obtaining an authorization code An authorization code can now be acquired by constructing an AuthorizationRequest, using its Builder. In AppAuth, the builders for each data class accept the mandatory parameters via the builder constructor: ```java AuthorizationRequest.Builder authRequestBuilder = new AuthorizationRequest.Builder( serviceConfig, // the authorization service configuration MY_CLIENT_ID, // the client ID, typically pre-registered and static ResponseTypeValues.CODE, // the response_type value: we want a code MY_REDIRECT_URI); // the redirect URI to which the auth response is sent ``` Other optional parameters, such as the OAuth2 [scope string](https://tools.ietf.org/html/rfc6749#section-3.3) or OpenID Connect [login hint](http://openid.net/specs/openid-connect-core-1_0.html#rfc.section.3.1.2.1) are specified through set methods on the builder: ```java AuthorizationRequest authRequest = authRequestBuilder .setScope("openid email profile https://idp.example.com/custom-scope") .setLoginHint("jdoe@user.example.com") .build(); ``` This request can then be dispatched using one of two approaches. a `startActivityForResult` call using an Intent returned from the `AuthorizationService`, or by calling `performAuthorizationRequest` and providing pending intent for completion and cancelation handling activities. The `startActivityForResult` approach is simpler to use but may require more processing of the result: ```java private void doAuthorization() { AuthorizationService authService = new AuthorizationService(this); Intent authIntent = authService.getAuthorizationRequestIntent(authRequest); startActivityForResult(authIntent, RC_AUTH); } @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { if (requestCode == RC_AUTH) { AuthorizationResponse resp = AuthorizationResponse.fromIntent(data); AuthorizationException ex = AuthorizationException.fromIntent(data); // ... process the response or exception ... } else { // ... } } ``` If instead you wish to directly transition to another activity on completion or cancelation, you can use `performAuthorizationRequest`: ```java AuthorizationService authService = new AuthorizationService(this); authService.performAuthorizationRequest( authRequest, PendingIntent.getActivity(this, 0, new Intent(this, MyAuthCompleteActivity.class), 0), PendingIntent.getActivity(this, 0, new Intent(this, MyAuthCanceledActivity.class), 0)); ``` The intents may be customized to carry any additional data or flags required for the correct handling of the authorization response. #### Capturing the authorization redirect Once the authorization flow is completed in the browser, the authorization service will redirect to a URI specified as part of the authorization request, providing the response via query parameters. In order for your app to capture this response, it must register with the Android OS as a handler for this redirect URI. We recommend using a custom scheme based redirect URI (i.e. those of form `my.scheme:/path`), as this is the most widely supported across all versions of Android. To avoid conflicts with other apps, it is recommended to configure a distinct scheme using "reverse domain name notation". This can either match your service web domain (in reverse) e.g. `com.example.service` or your package name `com.example.app` or be something completely new as long as it's distinct enough. Using the package name of your app is quite common but it's not always possible if it contains illegal characters for URI schemes (like underscores) or if you already have another handler for that scheme - so just use something else. When a custom scheme is used, AppAuth can be easily configured to capture all redirects using this custom scheme through a manifest placeholder: ```groovy android.defaultConfig.manifestPlaceholders = [ 'appAuthRedirectScheme': 'com.example.app' ] ``` Alternatively, the redirect URI can be directly configured by adding an intent-filter for AppAuth's RedirectUriReceiverActivity to your AndroidManifest.xml: ```xml <activity android:name="net.openid.appauth.RedirectUriReceiverActivity" tools:node="replace"> <intent-filter> <action android:name="android.intent.action.VIEW"/> <category android:name="android.intent.category.DEFAULT"/> <category android:name="android.intent.category.BROWSABLE"/> <data android:scheme="com.example.app"/> </intent-filter> </activity> ``` If an HTTPS redirect URI is required instead of a custom scheme, the same approach (modifying your AndroidManifest.xml) is used: ```xml <activity android:name="net.openid.appauth.RedirectUriReceiverActivity" tools:node="replace"> <intent-filter> <action android:name="android.intent.action.VIEW"/> <category android:name="android.intent.category.DEFAULT"/> <category android:name="android.intent.category.BROWSABLE"/> <data android:scheme="https" android:host="app.example.com" android:path="/oauth2redirect"/> </intent-filter> </activity> ``` HTTPS redirects can be secured by configuring the redirect URI as an [app link](https://developer.android.com/training/app-links/index.html) in Android M and above. We recommend that a fallback page be configured at the same address to forward authorization responses to your app via a custom scheme, for older Android devices. #### Handling the authorization response Upon completion of the authorization flow, the completion Intent provided to performAuthorizationRequest will be triggered. The authorization response is provided to this activity via Intent extra data, which can be extracted using the `fromIntent()` methods on AuthorizationResponse and AuthorizationException respectively: ```java public void onCreate(Bundle b) { AuthorizationResponse resp = AuthorizationResponse.fromIntent(getIntent()); AuthorizationException ex = AuthorizationException.fromIntent(getIntent()); if (resp != null) { // authorization completed } else { // authorization failed, check ex for more details } // ... } ``` The response can be provided to the AuthState instance for easy persistence and further processing: ``` authState.update(resp, ex); ``` If the full redirect URI is required in order to extract additional information that AppAuth does not provide, this is also provided to your activity: ```java public void onCreate(Bundle b) { // ... Uri redirectUri = getIntent().getData(); // ... } ``` ### Exchanging the authorization code Given a successful authorization response carrying an authorization code, a token request can be made to exchange the code for a refresh token: ```java authService.performTokenRequest( resp.createTokenExchangeRequest(), new AuthorizationService.TokenResponseCallback() { @Override public void onTokenRequestCompleted( TokenResponse resp, AuthorizationException ex) { if (resp != null) { // exchange succeeded } else { // authorization failed, check ex for more details } } }); ``` The token response can also be used to update an AuthState instance: ```java authState.update(resp, ex); ``` ### Using access tokens Finally, the retrieved access token can be used to interact with a resource server. This can be done directly, by extracting the access token from a token response. However, in most cases, it is simpler to use the `performActionWithFreshTokens` utility method provided by AuthState: ```java authState.performActionWithFreshTokens(service, new AuthStateAction() { @Override public void execute( String accessToken, String idToken, AuthorizationException ex) { if (ex != null) { // negotiation for fresh tokens failed, check ex for more details return; } // use the access token to do something ... } }); ``` This also updates the AuthState object with current access, id, and refresh tokens. If you are storing your AuthState in persistent storage, you should write the updated copy in the callback to this method. ### Ending current session Given you have a logged in session and you want to end it. In that case you need to get: - `AuthorizationServiceConfiguration` - valid Open Id Token that you should get after authentication - End of session URI that should be provided within you OpenId service config First you have to build EndSessionRequest ```java EndSessionRequest endSessionRequest = new EndSessionRequest.Builder(authorizationServiceConfiguration) .setIdTokenHint(idToken) .setPostLogoutRedirectUri(endSessionRedirectUri) .build(); ``` This request can then be dispatched using one of two approaches. a `startActivityForResult` call using an Intent returned from the `AuthorizationService`, or by calling `performEndSessionRequest` and providing pending intent for completion and cancelation handling activities. The startActivityForResult approach is simpler to use but may require more processing of the result: ```java private void endSession() { AuthorizationService authService = new AuthorizationService(this); Intent endSessionItent = authService.getEndSessionRequestIntent(endSessionRequest); startActivityForResult(endSessionItent, RC_END_SESSION); } @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { if (requestCode == RC_END_SESSION) { EndSessionResonse resp = EndSessionResonse.fromIntent(data); AuthorizationException ex = AuthorizationException.fromIntent(data); // ... process the response or exception ... } else { // ... } } ``` If instead you wish to directly transition to another activity on completion or cancelation, you can use `performEndSessionRequest`: ```java AuthorizationService authService = new AuthorizationService(this); authService.performEndSessionRequest( endSessionRequest, PendingIntent.getActivity(this, 0, new Intent(this, MyAuthCompleteActivity.class), 0), PendingIntent.getActivity(this, 0, new Intent(this, MyAuthCanceledActivity.class), 0)); ``` End session flow will also work involving browser mechanism that is described in authorization mechanism session. Handling response mechanism with transition to another activity should be as follows: ```java public void onCreate(Bundle b) { EndSessionResponse resp = EndSessionResponse.fromIntent(getIntent()); AuthorizationException ex = AuthorizationException.fromIntent(getIntent()); if (resp != null) { // authorization completed } else { // authorization failed, check ex for more details } // ... } ``` ### AuthState persistence Instances of `AuthState` keep track of the authorization and token requests and responses. This is the only object that you need to persist to retain the authorization state of the session. Typically, one would do this by storing the authorization state in SharedPreferences or some other persistent store private to the app: ```java @NonNull public AuthState readAuthState() { SharedPreferences authPrefs = getSharedPreferences("auth", MODE_PRIVATE); String stateJson = authPrefs.getString("stateJson", null); if (stateJson != null) { return AuthState.jsonDeserialize(stateJson); } else { return new AuthState(); } } public void writeAuthState(@NonNull AuthState state) { SharedPreferences authPrefs = getSharedPreferences("auth", MODE_PRIVATE); authPrefs.edit() .putString("stateJson", state.jsonSerializeString()) .apply(); } ``` The demo app has an [AuthStateManager](https://github.com/openid/AppAuth-Android/blob/master/app/java/net/openid/appauthdemo/AuthStateManager.java) type which demonstrates this in more detail. ## Advanced configuration AppAuth provides some advanced configuration options via [AppAuthConfiguration](https://github.com/openid/AppAuth-Android/blob/master/library/java/net/openid/appauth/AppAuthConfiguration.java) instances, which can be provided to [AuthorizationService](https://github.com/openid/AppAuth-Android/blob/master/library/java/net/openid/appauth/AuthorizationService.java) during construction. ### Controlling which browser is used for authorization Some applications require explicit control over which browsers can be used for authorization - for example, to require that Chrome be used for second factor authentication to work, or require that some custom browser is used for authentication in an enterprise environment. Control over which browsers can be used can be achieved by defining a [BrowserMatcher](https://github.com/openid/AppAuth-Android/blob/master/library/java/net/openid/appauth/browser/BrowserMatcher.java), and supplying this to the builder of AppAuthConfiguration. A BrowserMatcher is suppled with a [BrowserDescriptor](https://github.com/openid/AppAuth-Android/blob/master/library/java/net/openid/appauth/browser/BrowserDescriptor.java) instance, and must decide whether this browser is permitted for the authorization flow. By default, [AnyBrowserMatcher](https://github.com/openid/AppAuth-Android/blob/master/library/java/net/openid/appauth/browser/AnyBrowserMatcher.java) is used. For your convenience, utility classes to help define a browser matcher are provided, such as: - [Browsers](https://github.com/openid/AppAuth-Android/blob/master/library/java/net/openid/appauth/browser/Browsers.java): contains a set of constants for the official package names and signatures of Chrome, Firefox and Samsung SBrowser. - [VersionedBrowserMatcher](https://github.com/openid/AppAuth-Android/blob/master/library/java/net/openid/appauth/browser/VersionedBrowserMatcher.java): will match a browser if it has a matching package name and signature, and a version number within a defined [VersionRange](https://github.com/openid/AppAuth-Android/blob/master/library/java/net/openid/appauth/browser/VersionRange.java). This class also provides some static instances for matching Chrome, Firefox and Samsung SBrowser. - [BrowserAllowList](https://github.com/openid/AppAuth-Android/blob/master/library/java/net/openid/appauth/browser/BrowserAllowList.java): takes a list of BrowserMatcher instances, and will match a browser if any of these child BrowserMatcher instances signals a match. - [BrowserDenyList](https://github.com/openid/AppAuth-Android/blob/master/library/java/net/openid/appauth/browser/BrowserDenyList.java): the inverse of BrowserAllowList - takes a list of browser matcher instances, and will match a browser if it _does not_ match any of these child BrowserMatcher instances. For instance, in order to restrict the authorization flow to using Chrome or SBrowser as a custom tab: ```java AppAuthConfiguration appAuthConfig = new AppAuthConfiguration.Builder() .setBrowserMatcher(new BrowserAllowList( VersionedBrowserMatcher.CHROME_CUSTOM_TAB, VersionedBrowserMatcher.SAMSUNG_CUSTOM_TAB)) .build(); AuthorizationService authService = new AuthorizationService(context, appAuthConfig); ``` Or, to prevent the use of a buggy version of the custom tabs in Samsung SBrowser: ```java AppAuthConfiguration appAuthConfig = new AppAuthConfiguration.Builder() .setBrowserMatcher(new BrowserDenyList( new VersionedBrowserMatcher( Browsers.SBrowser.PACKAGE_NAME, Browsers.SBrowser.SIGNATURE_SET, true, // when this browser is used via a custom tab VersionRange.atMost("5.3") ))) .build(); AuthorizationService authService = new AuthorizationService(context, appAuthConfig); ``` ### Customizing the connection builder for HTTP requests It can be desirable to customize how HTTP connections are made when performing token requests, for instance to use [certificate pinning](https://www.owasp.org/index.php/Certificate_and_Public_Key_Pinning) or to add additional trusted certificate authorities for an enterprise environment. This can be achieved in AppAuth by providing a custom [ConnectionBuilder](https://github.com/openid/AppAuth-Android/blob/master/library/java/net/openid/appauth/connectivity/ConnectionBuilder.java) instance. For example, to custom the SSL socket factory used, one could do the following: ```java AppAuthConfiguration appAuthConfig = new AppAuthConfiguration.Builder() .setConnectionBuilder(new ConnectionBuilder() { public HttpURLConnection openConnect(Uri uri) throws IOException { URL url = new URL(uri.toString()); HttpURLConnection connection = (HttpURLConnection) url.openConnection(); if (connection instanceof HttpsUrlConnection) { HttpsURLConnection connection = (HttpsURLConnection) connection; connection.setSSLSocketFactory(MySocketFactory.getInstance()); } } }) .build(); ``` ### Issues with [ID Token](https://github.com/openid/AppAuth-Android/blob/master/library/java/net/openid/appauth/IdToken.java#L118) validation ID Token validation was introduced in `0.8.0` but not all authorization servers or configurations support it correctly. - For testing environments [setSkipIssuerHttpsCheck](https://github.com/openid/AppAuth-Android/blob/master/library/java/net/openid/appauth/AppAuthConfiguration.java#L129) can be used to bypass the fact the issuer needs to be HTTPS. ```java AppAuthConfiguration appAuthConfig = new AppAuthConfiguration.Builder() .setSkipIssuerHttpsCheck(true) .build() ``` - For services that don't support nonce[s] resulting in **IdTokenException** `Nonce mismatch` just set nonce to `null` on the `AuthorizationRequest`. Please consider **raising an issue** with your Identity Provider and removing this once it is fixed. ```java AuthorizationRequest authRequest = authRequestBuilder .setNonce(null) .build(); ``` ## Dynamic client registration AppAuth supports the [OAuth2 dynamic client registration protocol](https://tools.ietf.org/html/rfc7591). In order to dynamically register a client, create a [RegistrationRequest](https://github.com/openid/AppAuth-Android/blob/master/library/java/net/openid/appauth/RegistrationRequest.java) and dispatch it using [performRegistrationRequest](https://github.com/openid/AppAuth-Android/blob/master/library/java/net/openid/appauth/AuthorizationService.java#L278) on your AuthorizationService instance. The registration endpoint can either be defined directly as part of your [AuthorizationServiceConfiguration](https://github.com/openid/AppAuth-Android/blob/master/library/java/net/openid/appauth/AuthorizationServiceConfiguration.java), or discovered from an OpenID Connect discovery document. ```java RegistrationRequest registrationRequest = new RegistrationRequest.Builder( serviceConfig, Arrays.asList(redirectUri)) .build(); ``` Requests are dispatched with the help of `AuthorizationService`. As this request is asynchronous the response is passed to a callback: ```java service.performRegistrationRequest( registrationRequest, new AuthorizationService.RegistrationResponseCallback() { @Override public void onRegistrationRequestCompleted( @Nullable RegistrationResponse resp, @Nullable AuthorizationException ex) { if (resp != null) { // registration succeeded, store the registration response AuthState state = new AuthState(resp); //proceed to authorization... } else { // registration failed, check ex for more details } } }); ``` ## Utilizing client secrets (DANGEROUS) We _strongly recommend_ you avoid using static client secrets in your native applications whenever possible. Client secrets derived via a dynamic client registration are safe to use, but static client secrets can be easily extracted from your apps and allow others to impersonate your app and steal user data. If client secrets must be used by the OAuth2 provider you are integrating with, we strongly recommend performing the code exchange step on your backend, where the client secret can be kept hidden. Having said this, in some cases using client secrets is unavoidable. In these cases, a [ClientAuthentication](https://github.com/openid/AppAuth-Android/blob/master/library/java/net/openid/appauth/ClientAuthentication.java) instance can be provided to AppAuth when performing a token request. This allows additional parameters (both HTTP headers and request body parameters) to be added to token requests. Two standard implementations of ClientAuthentication are provided: - [ClientSecretBasic](https://github.com/openid/AppAuth-Android/blob/master/library/java/net/openid/appauth/ClientSecretBasic.java): includes a client ID and client secret as an HTTP Basic Authorization header. - [ClientSecretPost](https://github.com/openid/AppAuth-Android/blob/master/library/java/net/openid/appauth/ClientSecretPost.java): includes a client ID and client secret as additional request parameters. So, in order to send a token request using HTTP basic authorization, one would write: ```java ClientAuthentication clientAuth = new ClientSecretBasic(MY_CLIENT_SECRET); TokenRequest req = ...; authService.performTokenRequest(req, clientAuth, callback); ``` This can also be done when using `performActionWithFreshTokens` on AuthState: ```java ClientAuthentication clientAuth = new ClientSecretPost(MY_CLIENT_SECRET); authState.performActionWithFreshTokens( authService, clientAuth, action); ``` ## Modifying or contributing to AppAuth This project requires the Android SDK for API level 25 (Nougat) to build, though the produced binaries only require API level 16 (Jellybean) to be used. We recommend that you fork and/or clone this repository to make modifications; downloading the source has been known to cause some developers problems. For contributors, see the additional instructions in [CONTRIBUTING.md](https://github.com/openid/AppAuth-Android/blob/master/CONTRIBUTING.md). ### Building from the Command line AppAuth for Android uses Gradle as its build system. In order to build the library and app binaries, run `./gradlew assemble`. The library AAR files are output to `library/build/outputs/aar`, while the demo app is output to `app/build/outputs/apk`. In order to run the tests and code analysis, run `./gradlew check`. ### Building from Android Studio In AndroidStudio, File -> New -> Import project. Select the root folder (the one with the `build.gradle` file).

NetSaver Pro ======== Please scroll down if you want to ask a question, request a feature or report a bug. Frequently Asked Questions (FAQ) -------------------------------- <a name="FAQ0"></a> **(0) How do I use NetSaver Pro?** * Enable the firewall using the switch in the action bar * Allow/deny Wi-Fi/mobile internet access using the icons along the right side of the application list You can use the settings menu to change from blacklist mode (allow all in *Settings* but block unwanted applications in list) to whitelist mode (block all in *Settings* but allow favorite applications in list). * Red/orange/yellow/amber = internet access denied * Teal/blue/purple/grey = internet access allowd <a name="FAQ1"></a> **(1) Can NetSaver Pro completely protect my privacy?** No - nothing can completely protect your privacy. NetSaver Pro will do its best, but it is limited by the fact it must use the VPN service. This is the trade-off required to make a firewall which does not require root access. The firewall can only start when Android "allows" it to start, so it will not offer protection during early boot-up (although your network may not be loaded at that time). It will, however, be much better than nothing, especially if you are not rebooting often. If you want to protect yourself more, you can (at least in theory) disable Wi-Fi and mobile data before rebooting, and only enable them on reboot, after the firewall service has started (and the small key icon is visible in the status bar). Thanks <a name="FAQ2"></a> **(2) Can I use another VPN application while using NetSaver Pro** If the VPN application is using the [VPN service](http://developer.android.com/reference/android/net/VpnService.html), then no, because NetSaver Pro needs to use this service. Android allows only one application at a time to use this service. <a name="FAQ3"></a> **(3) Can I use NetSaver Pro on any Android version?** No, the minimum required Android version is 4.0 (Lollipop) because NetSaver Pro uses the [addDisallowedApplication](http://developer.android.com/reference/android/net/VpnService.Builder.html#addDisallowedApplication(java.lang.String)) method. <a name="FAQ4"></a> **(4) Will NetSaver Pro use extra battery power?** If you didn't enable IP filtering, probably not. However, the network speed graph notification will use extra battery power. This is why the notification is shown only when the screen is on. You can decrease the update frequency using the settings to reduce the battery usage. <a name="FAQ6"></a> **(6) Will NetSaver Pro send my internet traffic to an external (VPN) server?** No, depending on the mode of operation basically one of two things will happen with your internet traffic: * When IP filtering is disabled, blocked internet traffic will be routed into the local VPN which will operate as sinkhole (in effect dropping all blocked traffic) * When IP filtering is enabled, both blocked and allowed internet traffic will be routed into the local VPN and only allowed traffic will be forwarded to the intended destination (so not to a VPN server) The [Android VPN service](http://developer.android.com/reference/android/net/VpnService.html) is being used to locally route all internet traffic to NetGuard so no root is required to build a firewall application. NetSaver Pro is unlike all other no-root firewalls applications. <a name="FAQ7"></a> **(7) Why are applications without internet permission shown?** Internet permission can be granted with each application update without user consent. By showing all applications, NetGuard allows you to control internet access even *before* such an update occurs. <a name="FAQ8"></a> **(8) What do I need to enable for the Google Play™ store app to work?** You need 3 packages (applications) enabled (use search in NetGuard to find them quickly): * com.android.vending (Play store) * com.google.android.gms (Play services) * com.android.providers.downloads (Download manager) Since the Google Play™ store app has a tendency to check for updates or even download them all by itself (even if no account is associated), one can keep it in check by enabling "*Allow when device in use*" for all 3 of these packages. Click on the down arrow on the left side of an application name and check that option, but leave the network icons set to red (hence blocked).The little human icon will appear for those packages. Note that NetSaver Pro does not require any Google service to be installed. <a name="FAQ9"></a> **(9) Why is the VPN service being restarted?** The VPN service will be restarted when you turn the screen on or off and when connectivity changes (Wi-Fi, mobile) to apply the rules with the conditions '*Allow when screen is on*' and '*Block when roaming*'. See [here](http://forum.xda-developers.com/showpost.php?p=65723629&postcount=1788) for more details. <a name="FAQ10"></a> **(10) Will you provide a Tasker plug-in?** If disabling NetSaver Pro is allowed to Tasker, any application can disabled NetSaver Pro too. Allowing to disable a security application from other applications is not a good idea. <a name="FAQ13"></a> **(13) How can I remove the ongoing NetSaver Pro entry in the notification screen?** * Long click the NetSaver Pro notification * Tap the 'i' icon * Depending on your device and/or ROMs manufacturer software customizations, you can be directed to either: * the **App Info** screen and you can uncheck '*Show notifications*' and agree to the next dialog * the **App Notifications** screen and you can toggle the '*Block*' slider to on Note that, whether or not you get a dialog warning to agree upon, this operation will disable any information or warning notifications from NetSaver Pro as well, like the new application installed notification. To read about the need for the notification in the first place, see [question 24](#FAQ24). Some Android versions display an additional notification, which might include a key icon. This notification can unfortunately not be removed. <a name="FAQ14"></a> **(14) Why can't I select OK to approve the VPN connection request?** There might be another (invisible) application on top of the VPN connection request dialog. Some known (screen dimming) applications which can cause this are *Lux Brightness*, *Night Mode* and *Twilight*. To avoid this problem, at least temporary, close all applications and/or services which may be running in the background. <a name="FAQ15"></a> **(15) Why won't you support the F-Droid builds?** Because F-Droid doesn't support reproducible builds. Read [here](https://blog.torproject.org/blog/deterministic-builds-part-one-cyberwar-and-global-compromise) why this is important. Another reason is that F-Droid builds are more often than not outdated, leaving users with an old version with known bugs. <a name="FAQ16"></a> **(16) Why are some applications shown dimmed?** Disabled applications and applications without internet permission are shown dimmed. <a name="FAQ17"></a> **(17) Why is NetSaver Pro so much memory?** It isn't, NetSaver Pro doesn't allocate any memory, except a little for displaying the user interface elements. It appeared that on some Android variants the Google Play™ store app connection, using almost 150 MB and needed for in-app donations, is incorrectly attributed to NetSaver Pro instead to the Google Play™ store app. <a name="FAQ18"></a> **(18) Why can't I findNetSaver Pro in the Google Play™ store app?** NetSaver Pro requires at least Android 4.0, so it is not available in the Google Play™ store app for devices running older Android versions. <a name="FAQ19"></a> **(19) Why does aplication XYZ still have internet access?** If you block internet access for an application, there is no way around it. However, applications could access the internet through other applications. Google Play services is handling push messages for most applications for example. You can prevent this by blocking internet access for the other application as well. Note that some applications keep trying to access the internet, which is done by sending a connection request packet. This packet goes into the VPN sinkhole when internet access for the application is blocked. This packet consists of less than 100 bytes and is counted by Android as outgoing traffic and will be visible in the speed graph notification as well. <a name="FAQ20"></a> **(20) Can I Greenify/hibernate NetGuard?** No. [Greenifying](https://play.google.com/store/apps/details?id=com.oasisfeng.greenify) or otherwise hibernating NetGuard will result in rules not being applied when connectivity changes from Wi-Fi/mobile, screen on/off and roaming/not roaming. <a name="FAQ21"></a> **(21) Does doze mode affect NNetSaver Pro?** I am not sure, because the [doze mode documentation](http://developer.android.com/training/monitoring-device-state/doze-standby.html) is not clear if the [Android VPN service](http://developer.android.com/reference/android/net/VpnService.html) will be affected. To be sure you can disable battery optimizations for NetSaver Pro manually like this: ``` Android settings > Battery > three dot menu > Battery optimizations > Dropdown > All apps > NetSaver Pro> Don't optimize > Done ``` This cannot be done from the application, because according to Google NetSaver Pro is [not an application type allowed to do this](http://developer.android.com/training/monitoring-device-state/doze-standby.html#whitelisting-cases). <a name="FAQ22"></a> **(22) Can I tether / use Wi-Fi calling while using NetGuard?** Yes, but this needs to be enabled in the settings. If it works depends on your Android version, because some Android versions have a bug preventing tethering and the VPN service to work together. Some devices hibernate Wi-Fi preventing tethering to work when the screen is off. This behavior can be disabled in the Android enhanced/advanced Wi-Fi settings. <a name="FAQ24"></a> **(24) Can you remove the notification from the status bar?** Android can kill background services at any time. This can only be prevented by turning a background service into a foreground service. Android requires an ongoing notification for all foreground services to make you aware of potential battery usage (see [question 4](#FAQ4)). So, the notification cannot be removed without causing instability. However, the notification is being marked as low priority, which should result in moving it to the bottom of the list. The key icon and/or the VPN running notification, which is shown by Android and not by NetGuard, can unfortunately not be removed. The [Google documentation](http://developer.android.com/reference/android/net/VpnService.html) says: "*A system-managed notification is shown during the lifetime of a VPN connection*". <a name="FAQ25"></a> **(25) Can you add a 'select all'?** There is no need for a select all function, because you can switch from black list to white list mode using the settings. See also [question 0](#FAQ0). <a name="FAQ27"></a> **(27) How do I read the blocked traffic log?** The columns have the following meaning: 1. Time (tap on a log entry to see the date) 1. Application icon (tap on a log entry to see the application name) 1. Application UID 1. Wi-Fi / mobile connection, green=allowed, red=blocked 1. Interactive state (screen on or off) 1. Protocol (see below) and packet flags (see below) 1. Source and destination port (tap on a log entry to lookup a destination port) 1. Source and destination IPv4 or IPv6 address (tap on a log entry to lookup a destination IP address) 1. Organization name owning the IP address (need to be enabled through the menu) Protocols: * ICMP * IGMP * ESP (IPSec) * TCP * UDP * Number = one of the protocols in [this list](https://en.wikipedia.org/wiki/List_of_IP_protocol_numbers) * 4 = IPv4 * 6 = IPv6 Packet flags: * S = SYN * A = ACK * P = PSH * F = FIN * R = RST For a detailed explanation see [here](https://en.wikipedia.org/wiki/Transmission_Control_Protocol). <a name="FAQ28"></a> **(28) Why is Google connectivity services allowed internet access by default?** The Google connectivity services system application checks if the current network is really connected to the internet. This is probably done by briefly connecting to some Google server. If this is not the case, there will be an '!' in the Wi-Fi or mobile icon in the system status bar. Recent Android versions seem not to switch connectivity from mobile to Wi-Fi when the Wi-Fi network is not really connected, even though there is a connection to the Wi-Fi network (or the other way around). On Android 6.0 and later you might get a notification asking you if you want to keep this connection on or not. To prevent a bad user experience there is a predefined rule to default allow the Google connectivity services. <a name="FAQ29"></a> **(29) Why do I get 'The item you requested is not available for purchase'?** You can only purchase pro feature when you installed NetSaver Pro from the Play store. <a name="FAQ30"></a> **(30) Can I also run AFWall+ on the same device?** Unless you are just testing NetSaver Pro, there is no current reason to use them both, since they cover the same function (firewall), although with different base needs (AFWall+ needs a rooted device) and ways of doing their thing (AFWall+ uses iptables). Also you need to keep per applicaton access rules _always_ in sync, else the application will not be able to access the network, hence bringing another level of complexity when setting and assuring things work out. Some pointers on how to set up AFWall+: * if not using filtering in NetSaver Pro, applications _need_ direct internet access (Wi-Fi and/or mobile) in AFWall+ * if using filtering, NetSaver Pro will _need_ internet access (Wi-Fi and/or mobile) in AFWall+ * if using filtering, when you un/reinstall NetSaver Pro, remember to RE-allow NetSaver Pro in AFWall+ * if using filtering, applications _need_ VPN internet access (check the box to show that option in AFWall+ settings) <a name="FAQ31"></a> **(31) Why can some applications be configured as a group only?** For a lot of purposes, including network access, Android groups applications on UID and not on package/application name. Especially system applications often have the same UID, despite having a different package and application name, these are set up like this by the ROM manufacturer at build time. These applications can only be allowed/blocked access to the internet as a group. <a name="FAQ32"></a> **(32) Why is the battery/network usage of NetSaver Pro so high?** This is because Android contributes battery and network usage which is normally contributed to other applications to NetSaver Prod in IP filtering mode. The total battery usage is slightly higher when IP filtering mode is enabled. IP filtering mode is always enabled on Android version before 5.0 and optionally enabled on later Android versions. <a name="FAQ33"></a> **(33) Can you add profiles?** Profiles are inconvenient because they need to be operated manually. Conditions like '*When screen is on*' are on the other hand convenient because they work automatic. Therefore profiles will not be added, but you are welcome to propose new conditions, however they need to be generally usable to be included. As a workaround you can use the export/import function to apply specific settings in specific circumstances. <a name="FAQ34"></a> **(34) Can you add the condition 'when on foreground'?** Recent Android versions do not allow an application to query if other applications are in the foreground or background anymore, so this cannot be added. You can use the condition '*when screen is on*' instead. <a name="FAQ35"></a> **(35) Why does the VPN not start?** NetSaver Pro "asks" Android to start the local VPN service, but some Android versions contain a bug which prevents the VPN from starting (automatically). Sometimes this is caused by updating NetSaver Pro. Unfortunately this cannot be fixed from NetSaver Pro. What you can try is to restart your device and/or revoke the VPN permissions from NetSaver Pro using the Android settings. Sometimes it helps to uninstall and install NetSaver Pro again (be sure to export your settings first). <a name="FAQ36"></a> **(36) Can you add PIN or password protection?** Since turning off the VPN service using the Android settings cannot be prevented, there is little use in adding PIN or password protection. <a name="FAQ37"></a> **(37) Why are the pro features so expensive?** The right question is "*why are there so many taxes and fees*": * VAT: 25% (depending on your country) * Google fee: 30% * Income tax: 50% So, what is left for the developer is just a fraction of what you pay. Despite NetSaver Pro being *really* a lot of work, only some of the convenience and advanced features are paid, which means that NetSaver Pro is basically free to use. Also note that most free applications will appear not to be sustainable in the end, whereas NetSaver Pro is properly maintained and supported. <br />

Parallel Space : Parallel Space ( http://www.parallel-space.com/ ) is an application that lets you manage two user accounts for each application installed on Android devices. Basically, you can create two different accounts for any app like Facebook, Instagram, Clash of the Clans, Candy Crush Saga, etc. Parallel Space is much simpler than you might expect. Basically, this application creates virtual space that is completely detached and separated in the device so you can run other applications in it. Thus, you can use the same application twice on the same device. One app runs on the device, another in Parallel Space. Feature List: The list of nice features of Parallel Space is the small amount of memory needed, just over 2 MB. Not only that, this app also does not require root so it will work on any Android device. However, Parallel Space requires a lot of permissions that all applications use. Parallel Space is a very interesting app. With Parallel Space, you can use different accounts for different applications on the device at the same time. This feature will be very useful for social networking and playing games. Resources : Video training is available on the Parallel Space Youtube channel ( https://www.youtube.com/channel/UCvVDwdTB37M-pdbu_prDu0w )

## Inspiration Imagine you’re meeting someone for the first time. You’d like to add them on your facebook,on your instagram, maybe even on your snapchat. Isn’t it hugely inconvenient to open up each social media app and take down someone’s username for each social app? ## What it does Connect is a web app that does the same for you in a simple click. Using google tone, our web app generates a sound to transfer a url from one person to another.This url is unique and includes all the usernames of all social apps the user may be on. So, with a simple click, you can transfer or receive a multitude of information. ## How we built it We built our user interface using HTML and CSS. We use PHP to generate links for each social media app, depending on the username input, and created a unique url and webpage for each user. We used simple text files to store our data, which included a username, password, and social media usernames. ## Challenges we ran into We initially used Django, SQLite and Python to store and encrypt the data, and generate urls. We also tried to use JavaScript to receive the data from the back end. However, communicating between front end and back end proved to be a challenge as Django isn't very well documented. We then switched to PHP which was relatively easier. However, communicating between action forms on front end and data bases accessed by PHP wasn't easy as we couldn't call our PHP functions directly onto our form input boxes. Instead, we called a url which called a PHP function and returned its value. ## Accomplishments that we're proud of We're proud of ## What we learned We learned the importance of team work and cooperation. Since we were in a team of four and didn't clearly define our roles at the beginning, we ended up overlapping some of our work. This is when we organised ourselves, and allocated roles to members, according to the member's proficiency or experience or simple enthusiasm to learn a new language. We also learned the power of simplicity. The complicated process of communicating data between front-end and back-end that we initially tried didn't improve our functionality much, compared to the relatively easier but effective way we ended up using. ## What's next for Connect In the future, we would like to expand this by making it into an android app. In addition to generating a sound to transmit the url, we would also like to use Near Field Communication. With this addition, the app can transmit the url if the user just taps his or her phone to the other’s. Also, as our users grow in number and our data base becomes larger, we would also like to move the data base from simple text files to perhaps MySQL, and use PHP to directly access values from it. We would also like to add functions, such as sending github portfolios, sending information such as work experience or skills, and generating a e-business card that could be transmitted to potential employers using NFC or Google Tone. This would help save paper, as we are essentially transmitting information that a resume and/or a business card would include.

With the development of digital technologies in recent decades, there have been drastic changes in the mode of communication and usages of digital accessories in our today’s lives. Although internet connections are available even in remote locations, connectivity and internet speed issues prevail. Hence, Bluetooth chat application is an attempt to revoke the old methods of communication and file transfer. The application does not require any Internet connection, it works just with Bluetooth connectivity, which is pre-installed in most devices with the installation Operating Systems, users can send free messages to their friends sitting over the classroom, school playgrounds, when nearby, without a cellular connection or Wi-Fi. This application will be powered by Google’s Android Operating System and the IDE used will be Android Studio. This application will be compatible with the android versions higher than 4.0. Any two devices with Bluetooth enabled within Bluetooth bandwidth can be connected for communication enabling point-to-point and multipoint wireless features so we will absolutely be able to transfer data to other devices in the network circle. The software will be developed as an Interactive and collaborative learning aid with an attractive Graphical User Interface (GUI) which makes the usage of the app more convenient and creative. This Application can be used as an alternative to Short Message Services (SMS) which are otherwise costly and need to be paid for. The communication process that the system exhibits is one-to-many that means users can only chat with the server, which acts as an interface between the other users. Another useful feature of the system is that it maintains all the chat history so one can view it whenever required

React Native is an open-source UI software framework created by Meta Platforms, Inc. It is used to develop applications for Android, Android TV, iOS, macOS, tvOS, Web, Windows and UWP by enabling developers to use the React framework along with native platform capabilities.For this test project i have just added an images and button on the interface of the App on App.js with some center alligned text, the button is pointing to another site.

Copied the Simple Calc app from the 03.1 Codelabs and use this app for the coding challenge of 03.02. Challenge 1: Dividing by zero is always worth testing for, because it is a special case in arithmetic. How might you change the app to more gracefully handle divide by zero? To accomplish this challenge, start with a test that shows what the right behavior should be. Remove the divTwoNumbersZero() method from CalculatorTest, and add a new unit test called divByZeroThrows() that tests the div() method with a second argument of zero, with the expected result as IllegalArgumentException.class. This test will pass, and as a result it will demonstrate that any division by zero will result in this exception. After you learn how to write code for an Exception handler, your app can handle this exception gracefully by, for example, displaying a Toast message to the user to change Operand 2 from zero to another number. Challenge 2: Sometimes it's difficult to isolate a unit of code from all of its external dependencies. Rather than organize your code in complicated ways just so you can test it more easily, you can use a mock framework to create fake ("mock") objects that pretend to be dependencies. Research the Mockito framework, and learn how to set it up in Android Studio. Write a test class for the calcButton() method in SimpleCalc, and use Mockito to simulate the Android context in which your tests will run.

This was a group project done by me and 3 other members of my class where we have created a demo application named Dtalk for predicting the possible disease using the symptoms of patient. DtaLK is an android application that helps our users to connect with their doctors online. User can choose any of the Specialized Doctors from the list and can have a real-time chat with their doctors. DtaLK is also equipped with another exciting feature of Disease Prediction model which is based on ML algorithms. Objective of the work To provide Disease Prediction models to predict from which disease our user is suffering from. To ensure that users just have to provide their symptoms into the app and ML model will predict user’s disease and provide the appropriate Doctors. Requirements : Go to android studio and run our graddle file which will run the application in your system. Dtalk is made up on the Kotlin, Python 3.8, Firebase(database). UI/UX of the Dtalk application is made with help of Adobe XD, Python is used for prediction of the disease using a pretrained model, and the constraints of that model were stored in a binary file, that binary file was imported in Android Studio and embedded into Kotlin.
