        private void updateMember(){
            Toast.makeText(updataDelete.this,"updated successfully",Toast.LENGTH_SHORT).show();
         //inside here I want to update the bitmap image inside the URL without changing its download URL in the real-time database because at uploading for the first time I have uploaded the image in the storage and stored it URL in the real-time database now I want to update that image how should //I approach this ??
        }
    }

above written code was the activity that I used to update the image bitmap

Answer

It’s not possible. Each version of a file uploaded to storage has a unique URL. If the object in storage is changed by uploading a new version, then it will require a new URL (with a new token) to get the latest version.
