What's up with Android's back?
summary
Covers the full migration from API 1 to Android 14 with concrete recipes: onBackPressed deprecated, use AndroidX OnBackPressedDispatcher (Activity 1.6+) or the platform onBackInvokedCallback on API 33+, or flip the manifest flag enableOnBackInvokedCallback for simple apps. Demonstrates Activity 1.8.0 alpha’s back progress/start/cancel callbacks, AndroidX Transitions and material components (bottom sheet, side sheet) wired to predictive back, and working emulator demos plus a sample repo.
