This Android Project help you to make your image blur in fastest way

To make your imageview blurry in a single line of code, library using android framework (rendersript) which is most efficient for doing these tasks and you can grab this library using your Gradle file :

dependencies {
    ...
    Implementation 'com.jackandphantom.android:blurimage:1.2.0'
}

defaultConfig {
    ...
    renderscriptTargetApi 19
    renderscriptSupportModeEnabled true
}

This library has different methods which you can use to maintain your image blur.

BlurImage.with(getApplicationContext()).load(R.drawable.myImage).intensity(20).Async(true).into(imageView);
                                       OR                            
BlurImage.with(getApplicationContext()).load(bitmap_Image).intensity(20).Async(true).into(imageView);

method (load) :- load(int resource), load(Bitmap bitmap)

method(intesity):- intensity( int value) { Increase Blur and limit of value is in between 0 to 25 }

Synchronous way to Load :- To make blur in synchronous you need to put false in Async method.

ASynchronous way to Load:- To make blur in asynchronous (Background) you need to put true in Async method.

Direct get Blur Bitmap :- To get direct blur bitmap call the following code .

Bitmap bitmap = BlurImage.with(getApplicationContext()).load(R.drawable.mountain).intensity(20).Async(true).getImageBlur();
