In what situations is the Activity component recommended in Android app development?

The Activity component in Android represents a single screen of the user interface and is responsible for user interaction with the application.

It is recommended to use Activity in the following situations:

• When you need to present a separate screen with a unique UI and logic.
• To handle user actions related to a specific screen.
• When managing the lifecycle of a screen (creation, pause, resume, etc.).
• For navigation between different screens of the application.

For example, in a notes app, each note can open in a separate Activity, where the user can view or edit it.

If you need to display small parts of UI within a single screen, it is better to use fragments (Fragment) rather than creating many Activities.
