I am using Videoview to playback mp4 file from local machine using android emulator.
I hear the audio, but the screen is blank and no video is seen.
Android SDK 2.0.1

Does anyone have an idea what is missing here:

package com.hello;

import android.app.Activity;
import android.os.Bundle;
import android.widget.MediaController;
import android.widget.VideoView;

public class HelloAndroid extends Activity {

    VideoView vv;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);
        vv = (VideoView) findViewById(R.id.VideoView01);

        MediaController nc = new MediaController(this);
        vv.setMediaController(nc);

        vv.setVideoPath("/sdcard/yu.mp4");
        vv.requestFocus();
        vv.start();
    }

    public void onPause() {
        vv.stopPlayback();
    }
}
