What are the advantages and disadvantages of using the Activity component in Android development?

Advantages of using Activity:

• It is a fundamental component for displaying UI and interacting with the user.
• Manages the lifecycle of the screen, which helps to properly handle the application's state.
• Integrates with the Android system (e.g., back-press handling, navigation).

Disadvantages:

• Activity can be heavyweight, especially with a lot of logic, which complicates maintenance.
• Improper lifecycle management can lead to memory leaks.
• Often results in a large amount of code in a single class, reducing readability.

Therefore, modern applications are recommended to use architectural components (ViewModel, Navigation) and minimize logic in Activity, making it a "thin" layer between UI and business logic.
