MediaPlayer unable to prepare?

Question

I wrote a streaming radio app that is fairly basic in functionality but some devices refuse to "prepare" such as my Optimus One running 2.2. My app runs on other 2.2 devices any my brother's S2 running 2.3 and my Prime running 4.0.3.

Any idea why my specific devise will not prepare the audio?

Edit: Added some code below

private void togglePlay() {
    try {
        if(!this.player.isPlaying()) {
            this.player.setAudioStreamType(AudioManager.STREAM_MUSIC);
            this.player.setDataSource(this.address);
            this.player.prepareAsync();
        } else {
            this.player.reset();
        }
    } catch (IllegalArgumentException e) {
        ;
    } catch (IllegalStateException e) {
        ;
    } catch (IOException e) {
        ;
    }
}

Edit: Added ADB log

put your code "this.player.setDataSource(this, Uri.parse(getString(R.string.url))); this.player.prepare();" in try catch block. — deepak Sharma, Feb 21 '12 at 04:40
MediaPlayer is a buggy API, exponentially more so when it comes to http streaming. I ended up having to port FFmpeg to get around it's many problems. Post some code and I'll see if there's anything obviously wrong. — Reuben Scratton, Mar 08 '12 at 15:02
Thanks for the quick response! I've added a code snippet to the OP. Let me know if you need anything more. — Karai17, Mar 08 '12 at 19:13
Do you see problems on every play, including the first, or only after the first? — Reuben Scratton, Mar 08 '12 at 21:18
Adb says prepare failed every time I click play including the first. — Karai17, Mar 09 '12 at 02:14
What else does adb say? There should be error codes etc in the log — Reuben Scratton, Mar 09 '12 at 07:31

Updated the OP with an ADB log. It gives an "unhandled" error that seemingly means nothing. — Karai17, Mar 09 '12 at 12:25

You made need to drop a release() in there first. It could be crashing due to multiple mediaplayer instances.

player is only being initiated once. I'll update my post to better express my code layout – Karai17 Feb 21 '12 at 11:36

The interesting line from the log is this one:

Command PLAYER_INIT completed with an error or info PVMFFailure, -1

That's your error code, -1, which unfortunately is utterly generic ... it has no particular meaning. Fortunately the name, PVMFFailure is suitably Googlable... it looks from the linked thread that the media format is a likely suspect. Older platforms probably can't handle the same bitrates and formats as newer ones.

The same radio stream works well using XiiaLive. I'm not really sure what XiiaLitve does differantly than me but running ADB on that app shows they are using the MediaPlayer view and it is able to prepare properly. – Karai17 Mar 09 '12 at 18:10
You're saying that XiaaLive succeeds and your app fails *on the same device*? – Reuben Scratton Mar 09 '12 at 19:55

I just flashed CyanogenMod 7 on my phone and my app now works great. Apparently LG is retarded and likes to break things. Still not sure why other apps work and mine didn't but I'll just have to add a note to my app description explaining the issue to other LG users.
