RotationWatcher is a simple command-line application for detecting rotation changes on Android. While fairly useless by itself, it can be used together with other components such as minicap for screen capturing.
- Supports Android 2.3.3+
- Directly runnable as a command line application via adb shell
- Tracks and outputs current rotation in degrees to stdout
Build with ./gradlew assembleDebug.
Like mentioned earlier, RotationWatcher is a command line application. It does not have a launcher activity, or any activity for that matter. To run the application and read its output, the following steps must be performed:
-
Build the project. See above.
-
Choose a module based on your platform. While the mobile module should run on most platforms as-is, wear and tv versions are also provided just in case.
cd mobile -
Install the application.
adb install ./build/outputs/apk/*-debug.apk -
Figure out where the application was installed. Note that the location can and will change between every install, so always rerun this after installing.
apk_path=$(adb shell pm path jp.co.cyberagent.stf.rotationwatcher | tr -d '\r' | cut -d: -f 2) -
Run the application. Note that there's only ONE COMMAND to run, both the export and the exec run inside the device (the semicolon is escaped). The
export CLASSPATHis required for app_process to do its magic.adb shell export CLASSPATH="$apk_path"\; \ exec app_process /system/bin jp.co.cyberagent.stf.rotationwatcher.RotationWatcher
Alternatively, you may use the ./run.sh script in each module to do the same.
This application requires access to some private and/or hidden APIs. See shim/README.md for details.
