How to clear BitmapDrawable.getBitmap()' on a null object reference on a null object reference error

Question

Im using this library https://github.com/jgabrielfreitas/BlurImageView to blur images and everything works fine in a normal activity, recently i tried using this library in a custom GridView and got this error android.graphics.Bitmap android.graphics.drawable.BitmapDrawable.getBitmap()' on a null object reference This is my custom GridView adapter code to blur images gotten from a url with the help of Glide :

    image.setVisibility(View.INVISIBLE);
    Glide.with(getApplicationContext()).load(Uri.parse(lmap.get((int)_position).get("pic").toString())).into(image);
    t = new TimerTask() {
        @Override
        public void run() {
            runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    image.setVisibility(View.VISIBLE);
                    image.setBlur(15);
                }
            });
        }
    };
    _timer.schedule(t, (int)(2000));
}

NOTE: image.setBlur(15); is a function from the library.

Here is my custom GridView layout xml :

            </LinearLayout>
        </RelativeLayout>
    </androidx.cardview.widget.CardView>
</LinearLayout>

NOTE: Since im getting the image from a url i have removed app:src="drawable/img"

Answer 1

After spending almost a full day using different approach to solve the error, i finally found a way and it is simple as ABC i just needed to use a try catch statement on the image.setBlur(int) and it worked liked magic. A snippet from my GridView adapter would now look like this:

    @Override
    public void run() {
        runOnUiThread(new Runnable() {
            @Override
            public void run() {
                try{
                    image.setBlur(15);
                }catch(Exception e){
                     
                }
            }
        });
    }
};
_timer.schedule(t, (int)(2000)); ```
