Play sound and start vibration on animation repeat

I want to repeat sound and vibration with the repeat of an animation. I've cr开发者_JAVA技巧eated a mediaplayer object and starting it in onAnimationRepeat

public void onAnimationRepeat(Animation animation) {
    // TODO Auto-generated method stub
            mpDot.start();
    vibrator.vibrate(40L);


}

But nothing is happening. Neither the sound is repeating nor the vibration also onAnimationStart I've called mpDot.start() too... So whenever animation is started sound also starts and stops with it. But it doesn't repeat. Why?

Can anybody help.
