Android使用videoview播放res/raw下的视频并在结束后隐藏

final VideoView vv = (VideoView)findViewById(R.id.videoView1);
vv.setVideoURI(Uri.parse("android.resource://" + getPackageName() + "/" +R.raw.starttv));
vv.start();
       //播放结束侦听  
vv.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {  
            public void onCompletion(MediaPlayer mp) {  
                vv.setVisibility(View.INVISIBLE);
                
            }  
});

在模拟器播放不了，在真机可以
