I may have not got your answer correct  but you can try this   public void MusicController View view  throws IOException      switch  view getId             case R id play  mplayer start   break          case R id pause  mplayer pause    break          case R id stop              if mplayer isPlaying                      mplayer stop                    mplayer prepare                               break           where mplayer is defined in  onCreate method    as there is just one thread handling all  so stop   makes it die so we have to again prepare it If your intent is to start it again when your press start button it throws IO Exception  Or for better understanding of MediaPlayer you can refer to Android Media Player

just in case someone comes to this question  I have the easier version   public static MediaPlayer mp       Override     protected void onCreate Bundle savedInstanceState            super onCreate savedInstanceState           setContentView R layout activity main            Button b    Button  findViewById R id button           Button b2    Button  findViewById R id button2             b setOnClickListener new View OnClickListener                   Override             public void onClick View v                    mp   MediaPlayer create MainActivity this  R raw game                   mp start                                       b2 setOnClickListener new View OnClickListener                  Override             public void onClick View v                    mp stop                      mp start

You should use only one mediaplayer object      public class PlayaudioActivity extends Activity            private MediaPlayer mp               Called when the activity is first created              Override         public void onCreate Bundle savedInstanceState                super onCreate savedInstanceState               setContentView R layout main               Button b    Button  findViewById R id button1               Button b2    Button  findViewById R id button2               final TextView t    TextView  findViewById R id textView1                b setOnClickListener new View OnClickListener                       Override                 public void onClick View v                        stopPlaying                        mp   MediaPlayer create PlayaudioActivity this  R raw far                       mp start                                                    b2 setOnClickListener new View OnClickListener                       Override                 public void onClick View v                        stopPlaying                        mp   MediaPlayer create PlayaudioActivity this  R raw beet                       mp start                                                         private void stopPlaying                 if  mp    null                    mp stop                    mp release                    mp   null

According to the MediaPlayer life cycle  which you can view in the Android API guide  I think that you have to call reset   instead of stop    and after that prepare again the media player  use only one  to play the sound from the beginning  Take also into account that the sound may have finished  So I would also recommend to implement setOnCompletionListener   to make sure that if you try to play again the sound it doesn t fail

To stop the Media Player without the risk of an Illegal State Exception  you must do     try           mp reset            mp prepare            mp stop            mp release            mp null             catch  Exception e                        e printStackTrace                 rather than just   try          mp stop           mp release           mp null         catch  Exception e               e printStackTrace
