Answer 1

If you are in the fragment which is called from some activity, to get the reference to parent activity you can call it inside onViewCreated() or later hook methods of fragment directly by, it is just to make sure that parent activity is not null

getActivity()

If you want to really make sure you need to check first

if (getActivity() != null){ // then your logic with getActivity()}
