Android MediaPlayer takes too long to get ready

Question

Hey, I'm using MediaPlayer to play a regular ShoutCast stream. The code is simple with prepareAsync () and a handler to start playback. Although it works flawlessly with some streams, such as DI.FM or ETN.FM (http://u10.di.fm:80/di_progressive), with others (http://mp3.wpsu.org:8000/) t go through a state of readiness. Other listeners are not called.

//Uri streamUri = Uri.parse("http://u10.di.fm:80/di_progressive"); /* works */
Uri streamUri = Uri.parse("http://mp3.wpsu.org:8000/"); /* stuck on prepare state */
MediaPlayer mediaPlayer = new MediaPlayer();
mediaPlayer.setOnPreparedListener(new OnPreparedListener() {
    public void onPrepared(MediaPlayer mp) {
        mp.start();
    }
});
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mediaPlayer.setDataSource(this.getBaseContext(), streamUri);
mediaPlayer.prepareAsync();

Any feedback is appreciated!

I think there are compatibility issues with the end of the server. This is rather strange, because the emulator does this in my case - it’s just not on my Froyo Galaxy S, even if it's the same version of the API.

        if (!mp.isPlaying()){

            if (onBufferingUpdateCount>MAX_BUFFERING_UPDATES_AT_PREPARING_STATE)
                restartMP();
            onBufferingUpdateCount++;
            return;

private void restartMP(){
        if (mp!=null)
            if (mpState==MediaPlayerState.Preparing)
                actionCancel();
            else
                mp.reset();
    else
        mp = new MediaPlayer();
        mpState = MediaPlayerState.Idle;
        onBufferingUpdateCount=0;
