Explain the Android lifecycle for an activity.

Question

Accepted Answer

The Android activity lifecycle manages the states of an activity from creation to destruction, ensuring efficient resource use.

onCreate(): Initializes the activity, called when the activity is first created. Example: setContentView(R.layout.activity_main);
onStart(): Called when the activity becomes visible to the user. Example: Start animations or refresh UI.
onResume(): Called when the activity starts interacting with the user. Example: Resume paused tasks like video playback.
onPause(): Called when the system is about to start resuming another activity. Example: Save unsaved data.
onStop(): Called when the activity is no longer visible. Example: Release resources that are not needed.
onDestroy(): Called before the activity is destroyed. Example: Clean up resources or save final data.
