In Android mobile app development, a fragment is a reusable building block that represents a portion of a screen's user interface (UI). It essentially acts like a mini-activity within a larger activity.
Here are some key characteristics of fragments:
Modularity: Fragments promote modularity in app design. You can develop an app's UI by combining multiple independent fragments.
Reusability: A single fragment can be used in different parts of your app or even across different apps.
Lifecycle: Fragments have their own lifecycle that's tied to the lifecycle of the activity that contains them. This lifecycle allows you to handle events like fragment creation, visibility changes, and destruction.
Dynamic Addition/Removal: Fragments can be dynamically added, removed, or replaced within an activity while the app is running. This enables features like multi-pane layouts and tabbed interfaces.
Overall, fragments provide a powerful way to structure complex UIs in Android apps, making them more flexible, maintainable, and adaptable to different screen sizes and orientations.
