Proper handling of orientation changes makes rich user experience (not lost UI state) for the application and it also avoiding memory leaks. The restart behavior helps application to adapt new configurations by automatically reloading the application with alternative resources that match the new device configuration. When configurations changed during run time (such as screen orientation, keyboard availability, and language), Android usually destroys application’s existing Activity or Fragment and recreate it.Īndroid does this so that application can reload its resources based on the new configuration. When such changes occurs, Android restarts the running Activity means it destroy and again created. If orientation changes is not handle properly then it results unexpected behavior of the application.
Sometimes handling the orientation changes for your Activity, Fragment or AsyncTasks becomes most frustrating things to deal.
