BackStackEntry

interface BackStackEntry(source)

Representation of an entry on the fragment back stack, as created with FragmentTransaction.addToBackStack(). Entries can later be retrieved with FragmentManager.getBackStackEntryAt().

Note that you should never hold on to a BackStackEntry object; the identifier as returned by getId is the only thing that will be persisted across activity instances.
