you should pausing mediaplayer instance in onpause() method.
code, final mediaplayer angry exist in oncreate() method local object variable. fix problem, need move out angry object oncreate() method, can access onpause() method. here's example:

import android.media.mediaplayer;  public class mainactivity extends actionbaractivity { mediaplayer angry; //now here  @override protected void oncreate(bundle savedinstancestate) {      super.oncreate(savedinstancestate);      setcontentview(r.layout.activity_main);       angry = mediaplayer.create(mainactivity.this, r.raw.angry); 

and should pause in onpause() method this:

@override public void onpause () {   if (angry != null)   {     angry.pause();     angry.stop();   }   super.onpause(); }
