Fragment vs Activity in Android Development

In Android development, both fragments and activities are fundamental building blocks of an application. Here are the key differences:

Activity

An activity represents a single screen with a user interface. It is a window that typically fills the entire screen, and it can contain multiple fragments. Activities have a lifecycle and are managed by the system.

Fragment

A fragment represents a behavior or a portion of user interface in an activity. Fragments are reusable components and can be combined in different ways within activities. They have their own lifecycle and can be added or removed dynamically.

When developing an Android application, activities are used to manage the overall flow and navigation within the app, while fragments are used to create modular and flexible UI components that can be re-used across different activities.

Understanding the differences between fragments and activities is essential for efficient Android development and creating powerful and responsive applications.
