Class MainActivity
(Figs. 8.14–8.23) manages the app’s fragments and coordinates the interactions between them. On phones, MainActivity

always displays the ContactListFragment
at the left of the layout and, depending on the context, displays either the DetailsFragment
or the AddEditFragment
in the right two-thirds of the layout.
