The app:startDestination at each level of the nested graphs determines the backstack. Now that you have an AppBarConfiguration, you can call NavigationUI.setupActionBarWithNavController. The arrows between the destinations are called actions. The FILE menu opens several different options to update the maps. Provide navigation options to actions. Tap and hold on the home screen to see option to add widget. Open res/navigation/mobile_navigation.xml, and click the Design tab. B -> A. Double click app-debug.apk to open in APK Analyzer. A destination is any place you can navigate to in your app, usually a fragment or an activity. Google has recently announced various android libraries to introduce some best practices in the world of android during I/O 2018. As previously mentioned, the lines shown in the navigation graph are visual representations of actions. Launch your app using a deep link. Fragment is a modular section of any activity which has its own lifecycle, receives its own input events, and which you can add or remove while the activity is running (sort of like a “sub activity” that you can reuse in different activities). Open the mobile_navigation.xml file in Design mode. The navigation system also allows you to navigate via actions. The library provides a number of benefits, including: In this codelab, you will work with the sample app seen below: All the activities and fragments have already been created for you. Finally, let's use NavigationUI to configure the side navigation and navigation drawer, including handling the ActionBar and proper up navigation. e.g. Using Android’s Navigation Component, I wanted to keep certain fragments from appearing on the backstack. If the user goes from C to another fragment I decided to maintain B in the backstack (but you might want to not do that by moving line 15 within the if statement at line 17). To use the Navigation architecture component, you must use Android Studio 3.2 or higher. All of the changes you make in the graphical Navigation Editor change the underlying XML file, similar to the way the Layout Editor modifies the layout XML. 5.

In the tablet version (w960dp) the NavigationView is always on screen. As a convenience, you can also call NavController's createDeepLink() method to use the Context and current navigation graph from the NavController. Each element has a single required attribute: app:uri. is an element you can add to a destination in your graph. The click listener code would look like this: Each navigate() call has a not very exciting default transition associated with it, as seen below: The default transition, as well as other attributes associated with the call, can be overridden by including a set of NavOptions. Otherwise you will get an IllegalStateException. Perhaps they are trying to offer a more optimized standard api, who knows?
