How to switch to full screen by turning phone to landscape mode and not affecting the streaming video

I am creating a video streaming application , I want when I switch to landscape it goes to full screen but it should not load the video from the start again. I want to to switch smoothly without affecting the current playing.Help.

public class MainActivity extends Activity {
    VideoView videoView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        videoView = (VideoView) findViewById(R.id.vid);
        String vidAddress = "http://campusvibe.co.nf/blender.mp4";
        Uri vidUri = Uri.parse(vidAddress);

        MediaController vidControl = new MediaController(this);
        vidControl.setAnchorView(videoView);
        videoView.setMediaController(vidControl);
        videoView.setVideoURI(vidUri);
        videoView.start();


    }
}

This is for the portrait mode

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#3090C7">


        <VideoView
            android:id="@+id/vid"
            android:layout_width="fill_parent"
            android:layout_height="200dp"
            android:layout_gravity="center">
</VideoView>
    </RelativeLayout>

This is for the landscape mode

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#3090C7">

    <VideoView
        android:id="@+id/vid"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_gravity="center"></VideoView>
</RelativeLayout>

By default, each time you change an orientation, the view is recreated again. to prevent this you can use the android:configChanges="orientation but it is preferable to save the state as at when the orientation changes.

As your activity begins to stop, the system calls onSaveInstanceState() so your activity can save state information with a collection of key-value pairs. The default implementation of this method saves information about the state of the activity's view hierarchy, such as the text in an EditText widget or the scroll position of a ListView.

To save additional state information for your activity such as the position of the streaming video, you must implement onSaveInstanceState() and add key-value pairs to the Bundle object. For example:

...

 @Override
 public void onSaveInstanceState(Bundle savedInstanceState) {
// Save the current streaming position or state
       percentage = controls.getBufferPercentage()
       position =   controls.getCurrentPosition()
savedInstanceState.putInt("percentage", percentage);
savedInstanceState.putInt("position", position);

// Always call the superclass so it can save the view hierarchy state
super.onSaveInstanceState(savedInstanceState);
}

implement onRestoreInstanceState, this is called when re-creating.

public void onRestoreInstanceState(Bundle savedInstanceState) {
// Always call the superclass so it can restore the view hierarchy
super.onRestoreInstanceState(savedInstanceState);

// Restore state members from saved instance
mCurrentPosition = savedInstanceState.getInt("position");
mCurrentPercentage = savedInstanceState.getInt("percentage");

 // then you can use the MediaControls to restore the streaming app to the current position
}

I believe you could use this:

@Override
public void onSaveInstanceState(Bundle savedInstanceState) {
  super.onSaveInstanceState(savedInstanceState);
  // Save UI state changes to the savedInstanceState.
  // This bundle will be passed to onCreate if the process is
  // killed and restarted.
  savedInstanceState.putInt("movLength", mediaplayer.getCurrentPosition());
  // value equals to where user watched the
  // etc.
}

and on the activity check if the Bundle savedInstanceState != null:

  int movlength = 0;    
  if (savedInstanceState != null){
  movlength = savedInstanceState.getInt("movLength");
  }
  mediaplayer.seekto(movlength);
  // etc

Copy above to the onCreate method
