In my application I make a music background that works when click on a button start and the music changes loop sound1, sound2, sound3.

 public void startNewGame() {//initializing the sounds



   final  MediaPlayer sound1 = MediaPlayer.create(this, R.raw.music1);



   final MediaPlayer sound2 = MediaPlayer.create(this, R.raw.music2);



   final MediaPlayer sound3 = MediaPlayer.create(this, R.raw.music3);



    //generate random number

    Random randomGenerator = new Random();

    int randomInt = randomGenerator.nextInt(3) + 1;



    //picking the right sound to play

    switch (randomInt){

        case 1:

            if ( !sound1.isPlaying())

                sound1.setLooping(true);

              sound1.start();



            break;

        case 2:  if ( !sound2.isPlaying() )



                    sound2.setLooping(true);

                    sound2.start();



            break;

        case 3:  

                if ( !sound3.isPlaying() )

                sound3.setLooping(true);

                sound3.start();



           break;

    }



    mBtnChooseAndStart.setVisibility(View.GONE);

        getSupportFragmentManager()

                .beginTransaction()

                .replace(R.id.fl_board_container, 

   GameFragment.newInstance(mBitmapBricks, GOAL_STATUS))

                .commit();

    }

the pobelem is that when I click on another button start again that generates a dialogue after confirmation I start the game but with another sound that works and the first does not stop
how to solve this problem thanks in advance

 public void restart(View view) {



    if (mFullBitmap == null) {

        // Not started, so cannot restart

        UIUtils.toast(this, getString(R.string.not_started));

        return;

    }



    new AlertDialog.Builder(this)

            .setTitle(getString(R.string.restart))

            .setMessage(getString(R.string.confirm_restart_msg))

            .setPositiveButton(getString(R.string.confirm), new DialogInterface.OnClickListener() {

                @Override

                public void onClick(DialogInterface dialog, int which) {



                    startNewGame();

                }

            })

            .setNegativeButton(getString(R.string.cancel), new DialogInterface.OnClickListener() {

                @Override

                public void onClick(DialogInterface dialog, int which) {

                    dialog.dismiss();

                }

            })

            .show();

}

and also how to stop sounds in onBackpressed ().

finally I found the solution and it works
firstly create a method to stop mediaplayer

public void cleanUpMediaPlayer(){

    if(mediaPlayer != null) {

        if(mediaPlayer.isPlaying()) {

            mediaPlayer.stop();

        }

        mediaPlayer.release();

    }

}

then create a method of launching for each sound and within this method it is necessary to apply the functin to stop mediaplayer if it exist

public void sound1(){

    cleanUpMediaPlayer();

    mediaPlayer = MediaPlayer.create(this, R.raw.music1);

    mediaPlayer.setLooping(true);

    mediaPlayer.start();

}



public void sound2(){

    cleanUpMediaPlayer();

    mediaPlayer = MediaPlayer.create(this, R.raw.music2);

    mediaPlayer.setLooping(true);

    mediaPlayer.start();

}



public void sound3(){

    cleanUpMediaPlayer();

    mediaPlayer = MediaPlayer.create(this, R.raw.music3);

    mediaPlayer.setLooping(true);

    mediaPlayer.start();

}

finally call the sounds in the desired moment
for me I want the sounds to change every time I play my game that's why I use random with switch loop like this.

 Random randomGenerator = new Random();

    int randomInt = randomGenerator.nextInt(3) + 1;



    //picking the right sound to play

    switch (randomInt){

        case 1:

           sound1();



            break;

        case 2:

            sound2();



            break;

        case 3:

            sound3();



            break;



    }

the same for onBackPressed() you just have to call cleanUpMediaPlayer method

public void onBackPressed() {



 cleanUpMediaPlayer();

.....
}

a good day for my friend mistek :)
