Android- Mediaplayer streaming issue with test devices

I currently have a mediaplayer that is given a streamable datasource. I have two test devices: HTC Thunderbolt and a Samsung Galaxy SII Skyrocket.

The HTC device is able to stream the files perfectly fine; however, the galaxy sII cannot at all, and gives me a bunch of media player error codes.

I am implementing everything related to the media player properly...however, i can't get my head around this issue...how come it'll work on one phone but not the other? its the same link.

Any ideas? Logs from the devices below. Can post my code if necessary as well.

Thanks!

EDIT:

here is where i set the datasource....

SdrPlaylist p = mPlaylist.get(currentNum);

            String path = p.songUrl;

            artistInfo = p.songName;
            nextSong = Toast.makeText(getApplicationContext(),
                    "Buffering Next Song...", Toast.LENGTH_LONG);
            nextSong.setGravity(Gravity.TOP, 0, 110);
            nextSong.show();

            try {
                Log.d(TAG, "next song is: " + path);

                mediaPlayer.setDataSource(path);

                mediaPlayer.prepareAsync();
            } catch (IllegalArgumentException e) {
                e.printStackTrace();
            } catch (IllegalStateException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            }

The docs for MediaPlayer state:

For streams, you should call prepareAsync(), which returns immediately, rather than blocking until enough data has been buffered.

So I would start by trying that. You'll need to use the OnPreparedListener to call start() for you instead of assuming that prepare is finished after it returns. 

private MediaPlayer mp = new MediaPlayer();
mp.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
    @Override
    public void onPrepared(MediaPlayer arg0) {
        mp.start();

    }
});

mp.reset(); //<--- you probably shouldn't need this here.
mp.setDataSource(soundUri);
mp.prepareAsync();

That way you will be guaranteed not to be calling start() before the MediaPlayer is prepared.

If you are still having trouble after this change my next guess is that it is codec related. Media playback on android is a bit finicky, and that is doubly true for streaming Media. What type of file are you trying to play?

as it seems to be an issue of you setting the datasource of your mediaplayer here is how it should be done:

private MediaPlayer mp = new MediaPlayer();
mp.reset();
mp.setDataSource(soundUri);
mp.prepare();
mp.start();
