MediaPlayer stop playing after about 5 seconds

I had this problem too.
It was probably due to having the MediaPlayer-object only existing within a method.

For example:

//ERROR, stops after 5 sec!
public static void playMusic(int id)
{
  MediaPlayer mediaPlayer = MediaPlayer.create(context, id);
  mediaPlayer.setLooping(true);
  mediaPlayer.start();
}

It is most likely that the garbage collector will come in and clean away the MediaPlayer-object.

This fixed the error for me:

//mediaPlayer-object will not we cleaned away since someone holds a reference to it!
private static MediaPlayer mediaPlayer;

public static void playMusic(int id)
{
    mediaPlayer = MediaPlayer.create(context, id);
    mediaPlayer.setLooping(true);
    mediaPlayer.start();
}
