Question 1

?How can I communicate between Fragments in an Android app

Accepted Answer

Communication between Fragments in an Android app can be achieved using interfaces, shared ViewModels, or Fragment arguments. One approach is to define an interface in the parent Activity and implement it in the Fragments to pass data or trigger actions. Another method is to use shared ViewModels to store and share data between Fragments. Additionally, Fragment arguments can be used to pass data between Fragments during initialization.

Question 2

?What is the difference between a Fragment and an Activity in Android development

Accepted Answer

In Android development, an Activity represents a single, focused user interface screen, while a Fragment is a modular component that can be used within an Activity to create dynamic and flexible user interfaces. Activities are typically used to represent entire screens or user flows, while Fragments are used to divide the screen into independent sections, allowing for better code organization and reusability. Unlike Activities, Fragments can be added, removed, or replaced dynamically within an Activity's layout, making them ideal for creating multi-pane layouts or supporting various screen sizes and orientations.
