System On the netstart.mine (the default method)  

the code happens when there is an error ...

  Private Zero Lexoza () {Log D. ("Marda O", "Menda O"); Try {Log D. ("PERPIQET", "Perpetual Lexoose"); // error here is PlayM (FolderiS); } Hold (invalid record exception E) {message box ("Merpele", E. messages (.) ToString (), e.get (.) ToString ()); E.printStackTrace (); } Hold (Invalid State Exception e) {Message Box ("Merplete 1", E. Messages). ToString (), E.Gate (.) ToString ()); E.printStackTrace (); } Grip (IOE EXPRESS E) {Message Box ("Merple 2", EZET Message (). Toasting (), E.Gate (Coz.). Toasting ()); E.printStackTrace (); }}  

PlayM code is:

  Public Zero Playmay (string folder) removes illegal useless conclusions, illegalstate exception, IOException {AssetFileDescriptor = this. GetAssets () .openFd (folder + "/ Leximi.mp3"); Long start = descriptor .getStartOffset (); Long end = descriptor Tags (); MediaPlayer.setAudioStreamType (AudioManager.STREAM_MUSIC); Mediaplayer.setDataSource (descriptor.getFileDescriptor (), start, end); MediaPlayer.prepare (); MediaPlayer.start (); }  

and repeatedly clicks the player, but when I call PlayerClicks:

  releaseMediaPlayer (); Mediaplayer = new media player ();  

and the release media player code is:

  Private Zero Release Media Player (if {mediaplayer! = Null} {if (mediaplayer.isplaying ()) {MediaPlayer.stop (); } Mediaplayer.release (); Mediaplayer = null;  
  Thanks ..    
 Any help would be greatly appreciated ..  
 
 I got the solution ... The problem was, when I want to play a sound, I always declare a media player ...  
  mediaplayer .release (); Mediaplayer = null; Mediaplayer = new media player ();  
 
 No, I only use it: 
 
  mediaPlayer.reset (); MediaPlayer.setAudioStreamType (AudioManager.STREAM_MUSIC); Mediaplayer.setDataSource (descriptor.getFileDescriptor (), start, end); MediaPlayer.prepare (); MediaPlayer.start ();
