Remarks
Set a currently active fragment in this FragmentManager as the primary navigation fragment.
The primary navigation fragment's Fragment#getChildFragmentManager() child FragmentManager will be called first to process delegated navigation actions such as FragmentManager#popBackStack() if no ID or transaction name is provided to pop to. Navigation operations outside of the fragment system may choose to delegate those actions to the primary navigation fragment as returned by FragmentManager#getPrimaryNavigationFragment().
The fragment provided must currently be added to the FragmentManager to be set as a primary navigation fragment, or previously added as part of this transaction.
