		↳	androidx.navigation.dynamicfeatures.fragment.ui.DefaultProgressFragment

The default androidx.fragment.app.Fragment to display during installation progress.

This Fragment provides a default UI and handles split install state changes so you don't have to deal with this.

To create a custom progress fragment, extend AbstractProgressFragment.

Public functions

onDestroyView

open fun onDestroyView(): Unit

Called when the view previously created by onCreateView has been detached from the fragment. The next time the fragment needs to be displayed, a new view will be created. This is called after onStop and before onDestroy. It is called regardless of whether onCreateView returned a non-null view. Internally it is called after the view's state has been saved but before it has been removed from its parent.

onViewCreated

open fun onViewCreated(view: View, savedInstanceState: Bundle?): Unit
