Android :: How To Read RTSP Streaming?

To read RTSP streaming has been discussed a lot, but still not solved. Now android 1.5 realized, can RTSP streaming be played in android? The method setDateSource seems provide a way to receive RTSP streaming.
public void setDataSource (String path)

Sets the data source (file-path or http/rtsp URL) to use. Parameters path the path of the file, or the http/rtsp URL of the stream you want to play Throws IllegalStateException if it is called in an invalid state IOException IllegalArgumentException. Who knows how to use it? I wrote:

MediaPlayer mp =new MediaPlayer();
try { mp.setDataSource("rtsp://live.cri.cn/pop");
mp.setAudioStreamType(AudioManager.STREAM_MUSIC);
mp.prepare(); mp.start();
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block e.printStackTrace();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block e.printStackTrace();
}
But didn't work. May be the parameter in setAudioStreamType is wrong. Who knows?
