Migration or opt-out required for predictive back

The predictive back system animations (back-to-home, cross-task, and cross-activity) are enabled by default. onBackPressed is not called and KeyEvent.KEYCODE_BACK is not dispatched anymore.

Use OnBackPressedDispatcher

Device form factors

App orientation, resizability, and aspect ratio constraints are ignored on large screens by default, but every app that isn't fully ready can temporarily override this behavior by opting out (which results in the previous behavior of being placed in compatibility mode).

Safer Intents

With Android 16, shifts control to the receiving app, allowing developers to opt-in to strict intent resolution using their app manifest.
