Each element has a single required attribute: app:uri. The way Android manages tasks and the back stack, as described above—by placing all activities started in succession in the same task and in a "last in, first out" stack—works great for most apps and you shouldn't have to worry about how your activities are associated with tasks or how they exist in the back stack. The Navigation Architecture Component simplifies implementing navigation, while also helping you visualize your app's navigation flow.

It's better to use safe args. In the simplest way, you cannot access the back stack at runtime, it’s just open for testing. Because of its type safety, navigation using safe args generated classes is the preferred way to navigate by action and to pass arguments during navigation. In this step, you'll add a brand new destination. To handle other common UI components, such as the top app bar and bottom navigation, see Update UI components with NavigationUI.

In the tablet version (w960dp) the NavigationView is always on screen. Add the Deep Link widget to your home screen. These destinations do not display an "up" button in the app bar, and they display the drawer icon if the destination uses a drawer layout.
