This question is related specifically to the androidx.navigation library.
I split up my primary graph into 2 graphs because I wanted to have one with a bottom nav with the fragments above it and one without. Instead of using <include...
I added the activity to the first graph
<activity
android:id="@+id/Activity2"
android:name="com...Activity2"
android:label="Activity2" />
This all works nicely, but I also have a splash screen in the first graph that checks if the user is authenticated and navigates them directly into the second graph. With a fragment I can just use the standard popTo
and popToInclusive
to manage the fragment backstack but I have not been able to figure out how to do this with two activities so that when the second activity is launched the first is killed and removed from the backstack so the user cannot navigate backwards.
Currently I am just handling it in the fragment where the navigation occurs
navController
.navigate(R.id.action_someFragment_to_anotherFragment)
requireActivity().finish()
and this works but it leaves room for error and I'd like to deal with it with the navigation library if possible.
