How to blur background images in Android

Question

What is the best way to blur background images like the image below? I saw some code and libraries but their are a couple of years old or like BlurBehind library, but it doe

Answer 1

this might not be the most efficient solution but I had to use it since the wasabeef/Blurry library didn't work for me. this could be handy if you intend to have some getting-blurry animation:

1- you need to have 2 versions of the picture, normal one and the blurry one u make with photoshop or whatever

2- set the images fit on each other in your xml, then one of them could be seen and that's the upper one

3- set fadeout animation on the upper one:

final Animation fadeOut = new AlphaAnimation(1, 0);
        fadeOut.setInterpolator(new AccelerateInterpolator());
        fadeOut.setDuration(1000);


        fadeOut.setAnimationListener(new Animation.AnimationListener() {
            @Override
            public void onAnimationStart(Animation animation) {}

            @Override
            public void onAnimationEnd(Animation animation) {upperone.setVisibility(View.GONE);}

            @Override
            public void onAnimationRepeat(Animation animation) {}
        });

        upperone.startAnimation(fadeOut);
