Screen Behavior

Workout sessions typically require the screen to remain awake.

Permission

Add in AndroidManifest.xml:

<uses-permission android:name="android.permission.WAKE_LOCK" />

Activity flags

override fun onResume() {
    super.onResume()
    window.addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON)
}

override fun onStop() {
    super.onStop()
    window.clearFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON)
}

This keeps the screen active during workout playback and restores default behavior once the workout ends.
