What is the Activity lifecycle in Android?

The Activity lifecycle in Android refers to the various states an Activity goes through during its existence. Understanding the Activity lifecycle is essential for developing robust and efficient Android applications.

• onCreate: This method is called when the Activity is first created. It is typically used for initializing variables and setting up the layout.
• onStart: This method is called when the Activity is about to become visible to the user.
• onResume: This method is called when the Activity is visible and has focus.
• onPause: This method is called when the Activity is partially obscured by another Activity.
• onStop: This method is called when the Activity is no longer visible to the user.
• onDestroy: This method is called when the Activity is being destroyed and removed from memory.

Developers can override these lifecycle methods to perform specific actions or handle certain events at different stages of the Activity's life cycle.

By understanding and effectively managing the Activity lifecycle, developers can ensure their Android applications are responsive, efficient, and provide a seamless user experience.
