[android help] Why does my video view wont work?

I've research so many codes and yet my simple 3gpp video wo'nt play or work in the emulator when i clicked the button.

My question is why does my video view wont run? In log cat it shows many errors in AndroiRuntime.

Heres my manifest :

          android:name=".TutorialFive"
        android:label="@string/app_name"
        >

        
            

            
        
     

Heres the xml :

 
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >

    android:id="@+id/video1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"/>

Heres the java code:

   VideoView vid = (VideoView) findViewById(R.id.bThree);

    // to set the path of the video 

String urlpath = "android.resource://" + getPackageName() + "/" 
        + R.raw.xai;

MediaController mediaController = new MediaController(this);
mediaController.setAnchorView(vid);
vid.setMediaController(mediaController);
vid.setVideoURI(Uri.parse(urlpath));
 vid.start();
