Answer 1

I'm not sure thats what you want, but you can use Intent.ACTION_SCREEN_OFF to determine. see here an example.

Answer 2

You can check if the screen is turned off by calling isScreenOn method.

Note:This only can be used for 2.1 and above..

Answer 3

isScreenOn method returns only if the screen is on or off. It does not indicate the sleepy mode, because Android sleep mode is not same as Android screen off mode. In Android, sleep mode might come within milliseconds (depending on wakelocks) after screen off (idle mode) - but that's not guaranteed (referring to this post).

I think you can try using SystemClock.uptimeMillis(),SystemClock.elapsedRealtime() comparison.

Answer 4

Check out isInteractive()

PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT_WATCH) {
  return pm.isInteractive();
} else {
  return pm.isScreenOn();
}
