How does the visibility of an Activity's status reflect on its lifecycle process?

In Android, the visibility of an Activity directly affects its lifecycle and related methods. When an Activity becomes visible to the user, the onStart() and onResume() methods are called, and when it is no longer visible — onPause() and onStop().

• If the Activity is visible and in the foreground, it is in the Resumed state.
• If it is visible but not in the foreground (for example, partially covered), it is in the Started state.
• If it is not visible, it is in the Stopped state.

Thus, changes in visibility trigger transitions between these states and the corresponding lifecycle methods, allowing management of resources and Activity behavior depending on its current status.
