good afternoon composing team...
is it possible to share a compose navigation graph between multiple Activities?
my application has two acitvities that i wish to use the same nav graph.
I have a main Home screen which is used for the majority of user triggered interactions
however my app is also accessed via local notifications where i deeplink into another Activity
which all works fine, however when the user clicks BACK or UP they are returned to the device Home Page
where i wish for them to stay in my application

I would place AnotherActivity as one destination of the MainActivity(the one that contains HomeScreen) main_graph. Then would register MainActivity as the entry point for all notifications click intents. In the MainActivity having a NotificationHandler helper class that will determine where to go next based on the notification metadata.
That way you can build the desired path/route from the notification. Under normal circumstances, one graph for the whole App is more than enough.

yes, that would work
however there is one wrinkle in that the AnotherActivity does not have the same app bar as all the other screen under MainActivity
in fact AnotherActivity does have an app bar at all and with my MainActivity having a backdrop for the user to navigate around the app

Well that is UI stuff, is up to you if you want to keep the same topbar or use a different one. If your concern is to know whether to provide back navigation in AnotherActivity you could workaround it by passing that information in the input arguments. Pass a isRoot: Boolean field to indicate if you are launching it from another Activity or is the only Activity in the stack.
