E/AndroidRuntime: FATAL EXCEPTION: main
java.lang.ClassCastException: android.graphics.drawable.BitmapDrawable cannot be cast to com.bumptech.glide.load.resource.bitmap.GlideBitmapDrawable

Change this:

Bitmap photo = ((GlideBitmapDrawable)imageView.getDrawable().getCurrent()).getBitmap();

To this:

Bitmap photo = ((BitmapDrawable)imageView.getDrawable().getCurrent()).getBitmap();
