FragmentManager tracks a list of Fragments in the current Activity. Each Fragment can be assigned an ID or a TAG which can be used by the FragmentManager later to find it using the findFragmentById or findFragmentByTag methods. FragmentTransactions let you add, remove, replace or hide Fragments in Activities programmatically.
