Answer 1

Try this :)

IntentFilter intentFilter = new IntentFilter(Intent.ACTION_SCREEN_ON);
intentFilter.addAction(Intent.ACTION_SCREEN_OFF);
registerReceiver(new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction().equals(Intent.ACTION_SCREEN_OFF)) {
            //Stop your service
        } else if (intent.getAction().equals(Intent.ACTION_SCREEN_ON)) {
            // Start your service
        }
    }
}, intentFilter);

You can stop your background service in onStop() method of activity life cycle by using stopService(intent); and again start in onResume() method of activity life cycle by using startService(intent);
