import android.media.MediaPlayer;
import android.os.Bundle;
import android.os.Vibrator;
import android.support.v7.app.AppCompatActivity;
import android.view.MotionEvent;
import android.view.View;
import android.widget.ImageView;

import java.io.IOException;

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    final ImageView b = (ImageView) findViewById(R.id.bg1);
    final MediaPlayer mp = new MediaPlayer();
     b.setOnTouchListener(new View.OnTouchListener() {

         public boolean onTouch(View v, MotionEvent event) {
         Vibrator vb = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE);
             if ((event.getAction() & MotionEvent.ACTION_MASK) == MotionEvent.ACTION_DOWN) {
                 vb.vibrate(1000 * 60 * 10);//10mins
                 b.setImageResource(R.drawable.img2);

 //                     mp.seekTo(0);
//
////                    mp.reset(); 
//                     mp.start();
                 try {
                     mp.reset();
                     AssetFileDescriptor afd;
                     afd = getAssets().openFd("tr.mp3");
                     mp.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getLength());
                     mp.prepare();
                     mp.start();
                 }  catch (IOException e) {
                     e.printStackTrace();
                 }


                 return true;
             }
             if ((event.getAction() & MotionEvent.ACTION_MASK) == MotionEvent.ACTION_UP) {
                 vb.cancel();

                     mp.stop();


                 b.setImageResource(R.drawable.img1);
                 return false;
             }
             return false;
         }

     });

}

}

Answer 1

MediaPlayer mp;

Inside Oncreate()

mp= MediaPlayer.create(getApplicationContext(), R.raw.tr);

Music file should be in your raw directory

To start music

mp.start();
