What's up with Android's back
summary
History and migration path for Android back navigation with concrete guidance: use onBackPressedDispatcher (backward-compatible to API 21) or platform OnBackInvokedDispatcher on Android 13+, plus an application flag or per-activity flag for predictive gestures. Demos show Android 13 supports back-to-home animation while Android 14 adds cross-activity transitions, back progress (0–1) and Activity 1.8.0 APIs, AndroidX transitions 1.5.0 and Material 1.10.0-alpha3 support; sample repo included and a WhatsApp crop gesture bug contrasts with Samsung Gallery.
