Icecast dev - Jun 2014 - Android Java source for icecast streaming

Greetings,
tl;dr - I'm looking for sources to an Android Icecast client written in
Java.

long summary:
I maintain an open source Android app (WREK Online) that plays the live mp3
stream from the station's Icecast server.
Using the built in MediaPlayer class that is part of the Android SDK works OK.
As a developer, I just give it the streaming URL of the Icecast server, hook up
a few callbacks, and it plays just fine.  But this class has its limitations and
a few bugs.
The biggest limitation of Android's MediaPlayer class is that it can't
pull down the metadata from the Icecast server. It doesn't pass allow an
option for the developer to pass up an Ice-MetaData header for the specified
URL. And even if you could, it likely wouldn't be able to parse out the
inline metadata within the returned HTTP byte stream (as indicated by the
presence of an icy-metaint header).
So therefore, my app can't show the current artist and song title on the
screen very easily. An alternative option is to continuously make an http
polling request for the "status.xsl" page on the server and parse this
information out. But polling isn't an ideal solution.
I am considering going full on an writing my own replacement for MediaPlayer.
This would mean handling my own HTTP streaming, my own MP3 frame parser, 
additional code to extract out the metadata from the stream bytes, calling into
Android's MediaCodec APIs to convert to PCM, and ultimately into an
AudioTrack instance. All of which I am comfortable doing. However, this will
likely take me a better part of a week to get working with lots of testing and
bug fixing.
Is there an open-source solution I could potentially leverage? I know there are
few Linux projects written in C/C++ that have been ported to the Android NDK,
but I'd prefer an Android Java solution.  I've Google'd around, but
couldn't find anything definitive.
Suggestions?
Thanks,jSelbie

Rewriting everything is not necessary. I have a working solution for
metadata extraction, that still relies on MediaPlayer, I can license it for
a fair price.

I am using it here: http://radiofonia.net/android

Hi John,

We have evaluated and used RadioStreamsSDK
(http://www.binpress.com/app/radiostreams-sdk-for-android/964). Just another
option.

KJ

Hi jSelbie,
try to have a look to https://code.google.com/p/unicaradio-apps/.
Our developer created an app that obtain metadata by splitting icecast
stream and rebuilding it without metadata.

Thank you.  That's a nice looking radio app.
On that link below, I only see links to download pre-compiled APK files (apps).
Are there links to the actual source code available?
