BackStackEntry

Kotlin |Java

interface BackStackEntry

androidx.fragment.app.FragmentManager.BackStackEntry

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.
