This tutorial explains the Android Activity Lifecycle in a simple and beginner-friendly way. The Activity Lifecycle is one of the most important concepts in Android development because it controls how an app behaves when it is opened, paused, resumed, or closed.

In Android, an Activity represents a single screen in an app. Every activity goes through different states during its lifetime, such as onCreate, onStart, onResume, onPause, onStop, and onDestroy.
