What is the role of methods in the lifecycle process of an Activity component in Android?

The Activity lifecycle methods in Android manage screen states and allow performing specific actions during transitions between these states. The main methods:

• onCreate() — called when the Activity is created, typically used to initialize the interface and components.
• onStart() — the Activity becomes visible to the user.
• onResume() — the Activity starts interacting with the user (gains focus).
• onPause() — called when the Activity partially loses focus, for example, when a dialog appears or another Activity overlays.
• onStop() — the Activity is no longer visible to the user.
• onDestroy() — called before the Activity is destroyed, used to release resources.

These methods allow proper resource management, state saving, and ensure a smooth user experience.
