}

you have start button, pause button , stop button. there no resume button. when click start after pressing pause, media loads again , starts beginning (length = 0). have seek paused position , resume :

define global variable :

 int length = 0; 

in pause listener:

length=mediaplayer.getcurrentposition(); 

in resume (create resume listener):

        mediaplayer.seekto(length);         mediaplayer.start(); 

update

ideally pause , resume button same except toggle on-off changing image resource between play , pause pngs , execute relevant code of boolean variable :

in pause button listener:

 if(play)     {       //paused       play =false;       pause.setimageresource(r.id.pause);       length=mediaplayer.getcurrentposition();        mediaplayer.pause();     }else {        //resumed       play = true;       pause.setimageresource(r.id.resume);        mediaplayer.seekto(length);             mediaplayer.start();     } 

correct wherever necessary typed in editor not in ide.
