Service with MediaPlayer Force Closes

Postby jouiCK » Sun Aug 01, 2010 3:53 pm

I have a Service with a MediaPlayer which streams audio from the Internet but when I press the Home button and it goes back to the home screen it Force Closes. It's strange though because it works perfectly in the emulator and sometimes it doesn't Force Close on my phone (G1), when I've just turned it on. This is my code:

  1. public class backgroundPlayer extends Service {
  2.  
  3.  @Override
  4.  public IBinder onBind(Intent intent) {
  5.   return null;
  6.  }
  7.  
  8.  @Override
  9.  public void onCreate() {
  10.  
  11.  }
  12.  
  13.  @Override
  14.  public void onDestroy() {
  15.   MyMainClass.myMediaPlayer.stop();
  16.  }
  17.  
  18.  @Override
  19.  public void onStart(Intent intent, int startid) {
  20.   MyMainClass.myMediaPlayer.reset();
  21.  
  22.   try {  MyMainClass.myMediaPlayer.setDataSource(MyMainClass.channelUrl[player.selectedChannel]);
  23.   } catch (IllegalArgumentException e) {
  24.    // TODO Auto-generated catch block
  25.    e.printStackTrace();
  26.   } catch (IllegalStateException e) {

  30.    // TODO Auto-generated catch block
  31.    e.printStackTrace();

  33.   try {
  34.    MyMainClass.myMediaPlayer.prepare();

  42.   MyMainClass.myMediaPlayer.start();
  43.  }
