How to create motion saver screen in Android?

I saw a link developed by a designer for a mobile application. I want to achieve such an effect or animation. I do not know what to say for sure.

Tell me how I can achieve the same effect in the splash screen of an Android application.

Do I need a gif image and display in webview?

or any kind of drawing animation?

Any suggestions and help will be noticeable.

Thanks at Advance.

ImageView demoImage = (ImageView) findViewById(R.id.DemoImage);
int imagesToShow[] = { R.drawable.image1, R.drawable.image2,R.drawable.image3 };
animate(demoImage, imagesToShow, 0,false);  



private void animate(final ImageView imageView, final int images[], final int imageIndex, final boolean forever) {

//imageView <-- The View which displays the images
//images[] <-- Holds R references to the images to display
//imageIndex <-- index of the first image to show in images[] 
//forever <-- If equals true then after the last image it starts all over again with the first image resulting in an infinite loop. You have been warned.

int fadeInDuration = 500; // Configure time values here
int timeBetween = 3000;
int fadeOutDuration = 1000;

imageView.setVisibility(View.INVISIBLE);    //Visible or invisible by default - this will apply when the animation ends
imageView.setImageResource(images[imageIndex]);

Animation fadeIn = new AlphaAnimation(0, 1);
fadeIn.setInterpolator(new DecelerateInterpolator()); // add this
fadeIn.setDuration(fadeInDuration);

Animation fadeOut = new AlphaAnimation(1, 0);
fadeOut.setInterpolator(new AccelerateInterpolator()); // and this
fadeOut.setStartOffset(fadeInDuration + timeBetween);
fadeOut.setDuration(fadeOutDuration);

AnimationSet animation = new AnimationSet(false); // change to false
animation.addAnimation(fadeIn);
animation.addAnimation(fadeOut);
animation.setRepeatCount(1);
imageView.setAnimation(animation);

animation.setAnimationListener(new AnimationListener() {
    public void onAnimationEnd(Animation animation) {
        if (images.length - 1 > imageIndex) {
            animate(imageView, images, imageIndex + 1,forever); //Calls itself until it gets to the end of the array
        }
        else {
            if (forever == true){
            animate(imageView, images, 0,forever);  //Calls itself to start the animation all over again in a loop if forever = true
            }
        }
    }
    public void onAnimationRepeat(Animation animation) {
        // TODO Auto-generated method stub
    }
    public void onAnimationStart(Animation animation) {
        // TODO Auto-generated method stub
    }
});

}
