Description: Media Player does not play anything from network, neither with http nor rtsp links. It loads some data in buffer but there is no sound (or error messages) at all.
Steps to reproduce:

sample file:

package net.esmerla.android.player;

import android.app.Activity;
import android.media.AudioSystem;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.util.Log;

public class Player extends Activity {
    /** Called when the activity is first created. */

        private MediaPlayer player;

    @Override
    public void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        try {
                player = new MediaPlayer();

                player.setOnBufferingUpdateListener(mOnBufferingUpdateListener);
                player.setOnPreparedListener(mOnPreparedListener);
                player.setOnErrorListener(mOnErrorListener);
                player.setOnCompletionListener(mOnCompletionListener);

                player.setDataSource("http://myurl.com/fever.mp3");

                player.setAudioStreamType(AudioSystem.STREAM_MUSIC);
                Log.i(">>>>>","Preparing");
                player.prepareAsync();

                setContentView(R.layout.main);
        }catch(Exception e){
                Log.e(">>>>>","Error ",e);
        }

    }

    private MediaPlayer.OnBufferingUpdateListener mOnBufferingUpdateListener = new MediaPlayer.OnBufferingUpdateListener()
    {
        public void onBufferingUpdate(MediaPlayer mediaPlayer, int i) {
                Log.i(">>>", "Update buffer: " + i + "%");

                if (i == 20){
                        Log.i(">>>>>","Starting player");
                        mediaPlayer.start();
                        Log.i(">>>>>","Started player");
                }
        }
    };

    private MediaPlayer.OnPreparedListener mOnPreparedListener = new MediaPlayer.OnPreparedListener()
    {
        public void onPrepared(MediaPlayer mp) {
                Log.i(">>>","Prepared Listener");
        }
    };

    private MediaPlayer.OnErrorListener mOnErrorListener = new MediaPlayer.OnErrorListener()
    {
        public void onError(MediaPlayer mp, int what, int extra) {
                Log.i(">>>","Error on Listener, what: " + what + " extra: " + extra);
        }
    };

    private MediaPlayer.OnCompletionListener mOnCompletionListener = new MediaPlayer.OnCompletionListener()
    {
        public void onCompletion(MediaPlayer mp) {
                Log.i(">>>","Listener Completed");
        }
    };

}

Same code works fine for local files.

Note:
Needs more confirmations.
