Yes, using the support library Fragment along with the getSupportFragmentManager is the right thing to do.
we will use getChildFragmentManager() Return a private FragmentManager for placing and managing Fragments inside of this Fragment. we will use getParentFragmentManager() Return the FragmentManager for interacting with fragments associated with this fragment's activity.
Short answer: I call and use getChildFragmentManager() in my Fragment's onViewCreated() method. For example: @Override public void onViewCreated(View view, @Nullable Bundle savedInstanceState) { super.
The sources of version 1.2.0 explain it in more detail:
This has been removed in favor of
getParentFragmentManager(), which throws anIllegalStateExceptionif theFragmentManagerisnull. Check ifisAdded()returnsfalseto determine if theFragmentManagerisnull.
