What happens to an activity when the screen orientation changes?
Some device configurations can change during runtime (such as screen orientation, keyboard availability, and when the user enables multi-window mode). When such a change occurs, Android restarts the running Activity ( onDestroy() is called, followed by onCreate() ).
What happens when Android screen rotates?
When this accessibility setting is on, the screen automatically rotates when you move your device between portrait and landscape position. If you're using TalkBack, you might want to turn off auto-rotate, since rotating the screen can interrupt spoken feedback.
What does screen orientation do?
Auto rotate: Allows your device's screen orientation to automatically adjust and rotate depending on how you are holding your device. For example, if you turn your device sideways, the screen will automatically switch to Landscape mode.
How to avoid restarting activity when orientation changes on Android?
Prevent Activity to recreated
Another most common solution to dealing with orientation changes by setting the android:configChanges flag on your Activity in AndroidManifest. xml. Using this attribute your Activities won't be recreated and all your views and data will still be there after orientation change.
