Navigation and the Single Activity: Learnings from a Skeptic
summary
Practical account of adopting Android Jetpack navigation: the navigation component plus the SafeArgs plugin implements type‑safe arguments, generates deep links and directions, and moves screen wiring into an XML nav graph hosted by a NavHostFragment controlled by a NavController. Benefits include activity‑scoped resource sharing via shared ViewModel instances, correct up/back and stack behavior, and Android Studio graph tooling; caveats include no built‑in navigate‑for‑result yet and dynamic feature integration still pending. Migration strategy: replace activity screens with fragments hosted by a blank activity and incrementally convert logic.
