Do more with multi-window and activity embedding
summary
Android 12L+ makes multi-window first-class: Android 10 already changes lifecycle so all on-screen activities are resumed and apps must observe onTopResumedActivityChanged to acquire or release exclusive resources (camera, mic) or risk freezes/crashes. Activity Embedding uses a Jetpack library with an XML config and a SplitInitializer to declare splits (example 30/70, min width 600dp), auto-switches layouts at runtime, supports cross-app embedding on Android 13 with certificate or untrusted opt-in, and the sample fruit app runs side-by-side with zero refactor.
