Working with the Navigation Component
Learn how to work with Jetpack’s Navigation Component.
Introduction
Android Jetpack provides the Navigation Component library, which lets us handle all the navigation scenarios in the app. It standardizes how navigation is dealt with across different components in the app and allows us to build a consistent experience.
Navigation components
Navigation graph: This is an XML resource file containing all navigation destinations and details of paths to reach them. Navigation graphs are specific to the activity and are defined under the
res/navigation
directory.NavHost: This is a container that displays all fragment destinations. The library contains the
NavHostFragment
, which is the default implementation of theNavHost
.NavController: This is responsible for swapping the fragments in a
NavHost
.
Setting up the library
We need to add Navigation Component library dependencies in the app/build.gradle
file before we can use the APIs.
