Hi there,
The background of the viewer will be transparent when the withTransitionFrom(imageView) is null because of the alpha from the view_image_viewer.xml backgroundView is set to 0.
I tried by changing the alpha to 1 or deleting the alpha of the backgroundView. This made the background black again which is good.
