Question

I have a problem with correct dialog fragment dismissing after that orientation was changed. I guess that\'s due to old context because after that activity was recreated there w

Answer 1

Fix is found. Maybe, it's already was written in the one of the fixes of google community which helps to avoid simple dismissing on orientation change and I miss it.

I don't know already. In my case, I have set setRetainInstance(true) in onCreate method of DialogFragment.

Implemented onDismiss method with simple fix and my last minor problem was that I didn't remove super.onDestroyView() in onDismiss method. Now it's working like a charm.

Answer 2

Remove the setRetainInstance(true); from onCreateDialog(Bundle savedInstanceState) and keep it in onCreate(Bundle savedInstance) as follows :

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setRetainInstance(true);
}
