Trace an Activity's lifecycle when a user navigates away and returns

This tests your grasp of resource management and state preservation, not just method memorization. A great answer traces the flow: onPause -> onStop when navigating away, then onRestart -> onStart -> onResume upon return. Explain *why* each is called—onStop is for releasing heavy resources like a camera, while onPause is for brief interruptions. A major red flag is forgetting onRestart or failing to differentiate the purpose of onPause versus onStop, which shows a lack of practical experience.
