When should you use Fragments in Android development?

Fragments are a powerful part of Android development that allow for more flexible UI designs and can facilitate easier management of your app's user interface. Here are some circumstances when you should use Fragments:

• Dynamic UI Design: Use Fragments to create flexible UIs that can adapt to different screen sizes and orientations. This is especially useful for tablets vs. phones.
• Modularization: Fragments help in breaking down activity layouts into smaller components that can be managed independently, leading to cleaner code.
• Navigation Efficiency: For applications that require a multi-screen experience, Fragments can make navigating between screens smoother.
• Reusability: Fragments can be reused in different activities or multiple times within the same activity, promoting code reuse.
• Managing Lifecycle: Using Fragments can simplify handling back stack and managing the lifecycle of UI components within an activity.
