IllegalStateException for MediaPlayer.prepareAsync

Question

05-19 11:52:51.622: ERROR/MediaPlayer(1291): prepareAsync called in state 8
05-19 11:52:51.622: WARN/System.err(1291): java.lang.IllegalStateException

Answer 1

Your updated question:

1. Check whether you have INTERNET permission in your AndroidManifest.xml
2. Check whether you have some data connection enabled, as you want to stream from the internet
3. What do you mean with "this solution also fails"? Does it throw an IllegalStateException? From what I see, it just won't do anything at all, because you register your OnPreparedListener after the MediaPlayer object has prepared itself, causing the onPrepared() method never to be called.

A better approach would be to write:

MediaPlayer mp = new MediaPlayer();  
mp.setDataSource("http://.../movie.mp4");  
mp.setOnPreparedListener(this);  
mp.prepareAsync();
