Set a video as background

Question

I am making a login screen for my Android app and was wondering how can I use a video as a background rather than having an image or simple colors?

I want to make it

Answer 1

NatureDevil answer and video is great but 2 things are missing first if you click on a button and open a new activity like sing-up and decided to click on back arrow on the device, the home screen will give black screen because the video will not restart so you need to add this

@Override
protected void onResume() {
    super.onResume();
    // to restart the video after coming from other activity like Sing up
    mVideoView.start();


}

other thing for the VideoView to stretch from left to right full screen add:

android:layout_alignParentEnd="true"
android:layout_alignParentStart="true"
