Android – Interchange sounds through timer

Here you are:

final MediaPlayer sound1 = MediaPlayer.create(this, R.raw.snd1);
final MediaPlayer sound2 = MediaPlayer.create(this, R.raw.snd2);
int sound = 1;
Button play = (Button)findViewById(R.id.button1);

play.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        Timer timer = new Timer("click", true);
        TimerTask tone = new TimerTask(){
            @Override
            public void run(){
                if (sound % 4 != 0){
                sound1.start();
                sound += 1;
                }else{
                sound2.start();
                sound = 1;
            }
        };
        timer.scheduleAtFixedRate(tone, 500, 500);
    }
});
