Activity LifeCycle
Last updated
What is Activity LifeCycle?
The Activity lifecycle is a set of states and callbacks that an Activity goes through from creation to destruction. Key callbacks include onCreate, onStart, onResume, onPause, onStop, and onDestroy. Properly implementing these callbacks ensures the app handles interruptions like phone calls or screen rotations without data loss.
