MainActivity Method onAddContact

Method onAddContact (Fig. 8.19) from the ContactListFragment.ContactListFragmentListener interface is called by the ContactListFragment to notify the MainActivity when the user chooses to add a new contact. If the layout contains the fragmentContainer, line 97 calls displayAddEditFragment (Fig. 8.20) to display the AddEditFragment in the fragmentContainer; otherwise, line 99 calls displayAddEditFragment to display the Fragment in the rightPaneContainer. The second argument is a Bundle. Specifying null indicates that a new contact is being added.
