Answer from AI

Fragments in Android offer several advantages over using only activities:

  • Reusability of UI and logic. Fragments can be used in different activities, which simplifies maintenance and reduces code duplication.
  • Interface flexibility. Fragments allow creating adaptive interfaces, for example, displaying multiple fragments on a tablet and a single one on a phone.
  • Lifecycle management. Fragments have their own lifecycle, enabling more precise control over the state of UI components.
  • Simplified navigation. Fragments can be used to implement navigation within a single activity, avoiding the creation of multiple activities.

Example: In a news app, you can use one activity, and for displaying the list of articles and article details, different fragments are used, which are dynamically replaced depending on the device and screen orientation.
