Music play while buffering

[blueYufisher]

use AndroidVideoCache to cache music can't play while buffering, only when finished the buffer can play music, why?

HttpProxyCacheServer proxy = MainApplication.getProxy(mContext);
proxy.registerCacheListener(this, item.getSongUri());
String proxyUrl = proxy.getProxyUrl(item.getSongUri());
mMusicPlayer.setDataSource(proxyUrl);
mMusicPlayer.prepareAsync(); 
mMusicPlayer.setOnPreparedListener(this);
