Adventures in Navigation
summary
Demo of the Android Jetpack Navigation Component shows a concrete setup: a nav graph resource, a nav host fragment, and a NavController for navigate calls; use the safe args codegen to get type-safe action and arg classes; Navigation UI wires up bottom nav (3–5 top-level destinations), drawers and app bars and respects popUpTo to prune backstack. Deep links use NavDeepLinkBuilder; shared element transitions land in alpha6; multi-module/dynamic-feature graphs run but dynamic inflation currently fails and the library is still alpha.
