使用MediaPlayer收听网络电台？

Question

我正在尝试实施Android的MediaPlayer来收听流媒体网络。要做到这一点，我确实扩展了MediaPlayer，但是当我尝试启动时，播放器抛出异常。我认为流服务器是一个icecast并与ogg一起使用。这是流的网址：http://hdmediaserver2.info:8144/live

我怎么能这样做？

public class CustomMediaPlayer extends MediaPlayer{
    private static CustomMediaPlayer INSTANCE = null;

    private boolean isPause = false;

    public boolean isPause() {
        return isPause;
    }

    public void setPause(boolean isPause) {
        this.isPause = isPause;
    }

    private CustomMediaPlayer() {}

    public static CustomMediaPlayer getInstance(
            OnCompletionListener onCompeletionListener) {
        if (null == INSTANCE) {
            INSTANCE = new CustomMediaPlayer();
        }
        INSTANCE.setOnCompletionListener(onCompeletionListener);
        return INSTANCE;
    }

    @Override
    public void reset() {
        isPause = false;
        super.reset();
    }

    public void play() throws IllegalStateException, IOException {
        if (!isPause) {
            super.prepare();
        }
        super.start();
    }

    @Override
    public void stop() throws IllegalStateException {
        isPause = false;
        super.stop();
    }

    @Override
    public void pause() throws IllegalStateException {
        isPause = true;
        super.pause();
    }

    public void previousOrNext() throws IllegalStateException, IOException {
        isPause = false;
        play();
    }

}
