MediaPlayer mp;
AssetFileDescriptor descriptor;



@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout./////Your activity layout////);


        if(mp != null){
            if(mp.isPlaying()){
                mp.stop();
            }
        }

        try {
            descriptor = getAssets().openFd("////the name of your song.mp3////");            // song should be in assets folder
        } catch (IOException e) {
            e.printStackTrace();
        }


        audioPlayer();
    }



public void audioPlayer() {
        //set up MediaPlayer

        mp = new MediaPlayer();


        try {

            mp.setDataSource(descriptor.getFileDescriptor(), descriptor.getStartOffset(), descriptor.getLength());

            descriptor.close();

            mp.prepare();


        } catch (Exception e) {
            e.printStackTrace();
        }
    }



public void OnPlayPressed(View view){


        if(mp.isPlaying()){

            mp.pause();   

        }else{


            mp.start();           

        }


    }




    public void OnStopPressed(View view){



        mp.stop();

        try {
            descriptor = getAssets().openFd("////the name of your song.mp3////");         // song should be in assets folder
        } catch (IOException e) {
            e.printStackTrace();
        }

        audioPlayer();

    }

Create 2 buttons, 1 for start/pause and one for stop. "OnPlayPressed" is the listener for the first button and "OnStopPressed" is the listener for the second button.

Feel free to mess with this code as long as you get the logic behind it.

Edit: In onStopPressed i reinitialise the descriptor so that you could once again press the "play" button and play your song again. This is not necessary though. You could just write "mp.stop();".
