- 25. Changing Orientation Some device configurations can change during runtime (such as screen orientation, keyboard availability, and language). When such a change occurs, Android restarts the running Activity (onDestroy() is called, followed by onCreate()).
- 26. Changing Orientation The restart behavior is designed to help your application adapt to new configurations by automatically reloading your application with alternative resources that match the new device configuration.
- 28. Changing Orientation onCreate() or onRestoreInstanceState().
