Progressive audio caching library for Android

I'm using an android MediaPlayer class right now for progressive audio streaming like this:

MediaPlayer mp = new MediaPlayer();
mp.setDataSource(audioUrl);
mp.prepare();
mp.start();

But MediaPlayer class doesn't provide any caching, and I always need to do this routine: unnecessary network and battery waste

So, can someone help me find some library that will provide caching, because I couldn't find any. Thanks
