The Focus Keyword: Activities vs Fragments in Android Development

Activities and Fragments are key components in Android development that serve different purposes.

Activities

Activities represent the user interface screen in an Android application. They interact with the user and handle user input. Each activity is an independent unit with its own lifecycle and can be considered as a single screen or window in the app.

Fragments

Fragments are reusable components within activities that can be combined to create a multi-pane user interface. Fragments have their own lifecycle and can be dynamically added or removed from an activity. They are often used to create more flexible and responsive UI designs.

When to Use Each

Activities are typically used to represent top-level screens in an app, such as the main menu or settings screen. Fragments, on the other hand, are useful for creating modular and flexible UI elements within an activity. They are particularly beneficial for supporting multiple screen sizes and orientations.

When designing an Android app, consider using activities for standalone screens and fragments for reusable UI components within those screens for a more modular and maintainable codebase.
