Official Description: Android Navigation-Common

CommonsWare’s Notes

This artifact, as the name suggests, contains the common classes for the Jetpack Navigation component. In it, you will find classes like NavArgs, NavGraph, and so on.

Generally, you will not need to depend on this artifact directly. Your app will depend on higher-level artifacts, such as navigation-runtime, which will pull in this artifact via transitive dependencies.

See the navigation-runtime page for more resources related to the Navigation component.
