Android - Repeat sound in background X times with a Y delay each time

Rx with timer looks like the way to go. If you are not up for it Handler could work as well.

You can also use any timer idea but what I would do most likely is encapsulating the beep in a separate Runnable class and then will call it from my activity/fragment/view whenever it is needed.

public final class BeepRunnable implements Runnable {
    private final MediaPlayer mediaPlayer;
    private final View view;
    private final int repeats;
    private final int interval;
    private int currentRepeat;

    public BeepRunnable(@NonNull View view, int repeats, int interval) {
        this.view = view;
        mediaPlayer = MediaPlayer.create(this.view.getContext(), R.raw.beep);
        this.repeats = repeats;
        this.interval = interval;
    }

    @Override
    public void run() {
        mp.start();
        if (currentRepeat < repeats) {
            // set to beep again
            currentRepeat = currentRepeat + 1;
            view.postDelayed(this, interval);
        }
        else {
            // beep is over, just reset the counter
            reset();
        }
    }

    public void reset() {
        currentRepeat = 0;
    }

    public void destroy() {
        if (mediaPlayer.isPlaying()) {
            mediaPlayer.stop();
        }

        mediaPlayer.release();
        view.removeCallbacks(this);
    }
}

Then in you activity for example

public final ApplicationActivity extends Activity {
    private BeepRunnable beepRunnable;
    ...
    // in your place where you need to start the beeping
    beepRunnable = new BeepRunnable(anyNonNullView, 4, 500);
    anyNonNullView.post(beepRunnable);
}

public void onDestroy() {
    super.onDestroy();

    if (beepRunnable != null) {
        beepRunnable.destroy();
        beepRunnable = null;
    }
}
