Navigation Component

Navigation refers to the interactions that allow users to navigate across, into, and back out from the different pieces of content within your app. Android Jetpack's Navigation component helps you implement navigation, from simple button clicks to more complex patterns, such as app bars and the navigation drawer. The Navigation component also ensures a consistent and predictable user experience by adhering to an established set of principles. - Google

Basically, navigation components are a new alternative to fragment transactions. So that your application is of good quality with Single Activity. All actions are collected in one xml file and you can simply call the action if needed.
