Do more with multi-window and activity embedding
summary
Android now resumes all on-screen activities (Android 10+) and adds onTopResumedActivityChanged to signal the topmost one; exclusive resources like camera and mic still require careful release. Activity Embedding (Android 12L+) uses a Jetpack apps library with an XML split config (example: 600dp min width, 30/70 split) and is initialized via SplitInitializer, letting a list/detail app show two activities side‑by‑side with zero refactor. Cross‑app embedding (Android 13) is opt‑in via manifest—use SHA1 allowlist or allowUntrustedActivityEmbedding.
