An unfortunate side effect of this seems to be that the adapter is set to null before any pending fragment animations are completed.
In my project I add a PreferenceFragmentCompat to the backstack, specifying custom enter and exit animations. Now, when the user presses the back button I call FragmentManager.popBackStack() which in turn starts the custom exit animation.
The problem is that popBackstack() internally calls onDestroyView() on the PreferenceFragmentCompat to be removed. The PreferenceFragmentCompat calls unbindPreferences() which calls getListView().setAdapter(null).
The effect is that the list of preference items is cleared instantly before the exit animation even starts! This causes a white flicker and is clearly noticeable, the preference items disappear, then the view fades out.
Could you prevent setAdapter(null) from being called in this scenario? Maybe unregister the data observer instead?

Since the
Please file a bug against Fragments the with a sample project that reproduces this issue and we will be happy to take a look at what's going on.

I can confirm that using fragment 1.2.2 resolves the issue, thank you!
Without an explicit dependency declaration version 1.1.0 was still used (transient dependency of appcompat 1.1.0).
