The code I have so far is:

```
public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState){
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    public void SoundPlayer(View view) {
        MediaPlayer soundMediaPlayer1 = MediaPlayer.create(this, R.raw.gun_sound);
        soundMediaPlayer1.start();
    }

    public void DogSound(View view) {
        MediaPlayer soundMediaPlayer2 = MediaPlayer.create(this, R.raw.cat_sound);
        soundMediaPlayer2.start();
    }

    public void NewSound(View view) {
        MediaPlayer soundMediaPlayer3 = MediaPlayer.create(this, R.raw.new_sound);
        soundMediaPlayer3.start();
    }

    public void LaughTrack(View view) {
        MediaPlayer soundMediaPlayer12 = MediaPlayer.create(this, R.raw.laugh_sound);
        soundMediaPlayer12.start();
    }

    public void HorseSound(View view) {
        MediaPlayer soundMediaPlayer4 = MediaPlayer.create(this, R.raw.horse_sound);
        soundMediaPlayer4.start();
    }

    public void HeySound(View view) {
        MediaPlayer soundMediaPlayer5 = MediaPlayer.create(this, R.raw.hey_sound);
        soundMediaPlayer5.start();
    }

    private void Stop() {
        startActivity(new Intent(this, MainActivity.class));
    }

    public void stop(View view) {
        Stop();
    }

}

```

The problem I face is that all the sounds overlaps and plays. I have a STOP button set up, but have no idea has to how to make it stops the media. Any feedback is helpful. 

Thank you.
