下面这段代码是android中Music中的处理代码：

MediaPlayer.OnErrorListener errorListener = new MediaPlayer.OnErrorListener() {
    public boolean onError(MediaPlayer mp, int what, int extra) {
        switch (what) {
        case MediaPlayer.MEDIA_ERROR_SERVER_DIED:
            mIsInitialized = false;
            mCurrentMediaPlayer.release();
            mCurrentMediaPlayer = new CompatMediaPlayer(); 
            mCurrentMediaPlayer.setWakeMode(MediaPlaybackService.this, PowerManager.PARTIAL_WAKE_LOCK);
                 mHandler.sendMessageDelayed(mHandler.obtainMessage(SERVER_DIED), 2000);
            return true;
        default:
            Log.d("MultiPlayer", "Error: " + what + "," + extra);
            break;
        }
        return false;
   }
};
