java.lang.IllegalStateException: Can not perform this action after onSaveInstanceState with DialogFragment

Question

I am facing issue with DialogFragment / getSupportFragmentManager / Android version 4.x

Answer 1

fragmentView.post(() -> {
    FragmentTransaction ft = getActivity().getSupportFragmentManager().beginTransaction();
    YourDialog yourDialog = YourDialog.newInstance();
    yourDialog.show(ft, "text_data");
});

The goal of post() method in this case is to wait while onResume() of Activity or Fragment will finished. It works if you want to show DialogFragment from Fragment., f.e. when you want to show your dialog after a system dialog dismissed.
