to build, install, and run android example
cd <reindeer2d_path>/wks/android-studio
./gradlew installDebug
adb shell am start -n com.mrap.reindeer2d_example/android.app.NativeActivity && (adb shell pidof com.mrap.reindeer2d_example | xargs -I{} adb logcat --pid {})
if logcat doesn't show anything just reexecute command
adb shell pidof com.mrap.reindeer2d_example | xargs -I{} adb logcat --pid {}
alternatively in failure of aquiring pid from command pidof, running can also be executed with this:
adb shell am start -n com.mrap.reindeer2d_example/android.app.NativeActivity && (adb logcat | grep native-activity)
