Android Shoutcast internet Radio Streaming

Question

I developed Shoutcastinternet Radio Streaming and I'm able to stream and play Successfully.

But the problem is: when i execute my application,I'm able to stream and play Continuously for halfanhour,after that the stream is getting stopped(not able to play, after that if i click on again play the stream Continues and again after some time FileNotFoundException)?

I logged the Error, after Stream get stopped.

The Error is :

java.io.FileNotFoundException: /data/data/com.torilt/cache/downloadingMediaFile430 (No such file or directory)
Can't find file. Android must have deleted it on a clean up

Getting Exception in setupplayer()

Answer 1

you should call release(), to free the resources. If not released, too many MediaPlayer instances may result in an exception

Write this code when on youe Service

Updated

private void releaseMediaPlayer() {
if (mediaPlayer != null) {
    if(mediaPlayer.isPlaying()) {
        mediaPlayer.stop();
    }
    mediaPlayer.release();
    mediaPlayer = null;
  }
}

@Override
protected void onDestroy() {
   super.onDestroy();
   releaseMediaPlayer();
}

You can see this
