What is the difference between Activities and Fragments in Android?

Activities and Fragments are fundamental components in Android development.

Key Differences:

• Activities: An Activity represents a single screen with a user interface. It acts as a container for the UI elements and can be considered as a complete window where the user interacts.
• Fragments: Fragments are modular sections of an activity, allowing more flexible UI designs. They can be reused across different activities and help in creating dynamic and scalable UIs.

It is crucial to choose between Activities and Fragments based on the app requirements to ensure optimal performance and user experience.
