Blurry: NullPointerException: Attempt to invoke virtual method 'void android.graphics.Bitmap.recycle()' on a null object reference

I’m getting the following err:

Fatal Exception: java.lang.NullPointerException: Attempt to invoke virtual method 'void android.graphics.Bitmap.recycle()' on a null object reference
       at jp.wasabeef.blurry.internal.Blur.of(SourceFile:42)
       at jp.wasabeef.blurry.Blurry$Composer.onto(SourceFile:115)
       ...................

…while calling the following:

Blurry.with(activity)
    .radius(40)
    .sampling(2)
    .color(ResourcesUtil.getColor(R.color.dirtyBlack25))
    .onto(blurredView);

As far as I understood, the err occurs here inside of method of Blur class:

Bitmap cache = view.getDrawingCache();
cache.recycle();

Here, the drawing cache can be null sometimes. This err occurs rarely. However, could you please solve this and update the library accordingly?

For anybody facing this problem, this is probably related to running the code too soon after the view is loaded try this attach a runnable imageView.post(new Runnable() { @Override public void run() { Blurry.with(Payment.this) .radius(25) .sampling(2) .animate(500) .onto(payments); } });

Kotlin approach:

private fun Blurry.Composer.postOnto(view: ViewGroup) {
    view.post { onto(view) }
}

My solution，

handler.postDelayed(new Runnable() {

        @Override
        public void run() {
            Blurry.with(mContext).radius(25).capture(mImgAudio).into(mImgBlurryfloat);

        }
    },1000);
