    Use the Following code

    private void changeBlur(int value){
        Bitmap bmp = BitmapFactory.decodeResource(getResources(), R.drawable.background);

        Bitmap outputBitmap = Bitmap.createBitmap(bmp);

        final RenderScript rs = RenderScript.create( this );
        final Allocation input = Allocation.createFromBitmap( rs, bmp, Allocation.MipmapControl.MIPMAP_NONE, Allocation.USAGE_SCRIPT );
        final Allocation output = Allocation.createTyped( rs, input.getType() );
        final ScriptIntrinsicBlur script = ScriptIntrinsicBlur.create( rs, Element.U8_4(rs) );
        script.setRadius(value /* e.g. 3.f */);
        script.setInput(input);
        script.forEach(output);
        output.copyTo(outputBitmap);

        _imageView.setImageBitmap(outputBitmap);
    }

    the value passed to this method will blur the image to that level.

    Happy coding :)
