Hi,

Thanks for your response.
Seems like not a bug in the library.
I think the cause of this bug is that CropImageView.loadAsync() is called after the view has detached from window.

・You shouldn't hold the fragment in your custom view class because the reference loops and causes the memory leaks.
・You shouldn't inflate the view multiple time in the onActivityResult() . You should inflate the view only once in onCreateView() .

Please see my sample as reference.
