Navigation

The Navigation Architecture Component helps you easily implement common, but complex navigation requirements, while also helping you visualize your app's navigation flow. The library provides a number of benefits, including:

• Handling fragment transactions
• Handling up and back correctly by default
• Provides defaults for animations and transitions
• Deep linking is a first class operation
• Navigation UI patterns like navigation drawers and bottom nav with little additional work
• Type safety when passing information while navigating
• Android Studio offers tooling for visualizing and editing the navigation flow of an app
