created issue #1

Dec 9, 2018 03:07AM

Component used: Navigation
Version used: 1.0.0-alpha08
Devices/Android versions reproduced on:

Assuming:
- Main Activity has a NavHostFragment, which navigates between Fragment A & Fragment B
- Main activity handles going back with onSupportNavigateUp
- Fragment B has it's own NavHostFragment, which navigated between InnerFragmentB1 & InnerFragmentB2
- Parent NavHostFragment navigates from A -> B (which starts with B1)
- Sub NavHostFragment navigates from B1 -> B2
- Press up: Sub NavHostFragment returns to B1
- Press up: Parent NavHostFragment returns from B to A

What's the proper way of handling these types of situations where we'd like the back button to handle backing out of Inner Fragments first and then Outer Fragments after?

Merge Navigation Compose version back into Navigation

Rather than run Navigation Compose as a separate,
parallel project from the other Navigation artifacts,
merge the versions together so that we can better
integrate the artifacts together and leverage new
alpha features.

Test: ./gradlew bOS, ran Studio in FLAN and COMPOSE configs

Add routes to NavDestination

This change introduces the concept of a route to NavDestination. A route
is String that defines the path to the Destination. Setting the route on
a NavDestination will replace the any id that was set previously and
adds a deep link to the destination. You can set a route on the
NavDestination programatically, or through xml.

RelNote: "You can now add a route to your NavDestination"
