如何从android中的shoutcast中检索元数据?

我正在开发一个播放窗体的网址的播放器
shoucast http://292.3.23.23:8000是,因为我可以恢复
元数据?艺术家名称mediaplayer使用标题
没有问题,但我无法检索元数据
任何人都知道我能做什么,并在文本中显示
titulo.settext(title);

解决方法

检查这个 http://developer.android.com/reference/android/media/MediaMetadataRetriever.html,但它在API LEVEL 10

谢谢.

我已经使用线程,而不是伟大的解决方案,但它的作品

public class IcyStreamMeta {

        return "";

    String title = streamTitle.substring(0,streamTitle.indexOf("-"));

}

线程调用每10秒

public void startThread(){

    timer = new Timer();
    timer.schedule(new TimerTask() {
        public void run() {

            URL url;
            Message msg = handler.obtainMessage();
            try {
                url = new URL(URL);
                  IcyStreamMeta icy = new IcyStreamMeta(url);

                    Log.d("SONG",icy.getTitle());
                  msg.obj = icy.getTitle();

                Log.d("ARTITSi",icy.getArtist());
                handler.sendMessage(msg);
            } catch (MalformedURLException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

        }
    },10000);

}
