Using the tag, safeargs generates a class called FlowStepFragmentArgs. 7. On smaller devices the NavigationView is nested within a DrawerLayout. You can override this behavior by passing in an activity as the context or set an explicit activity class via setComponentName(). For more about the Navigation Component check out the documentation. The Principles of Navigation recommend you use activities as entry points for your app. Run the app and click the Navigate To Destination button. Here is what the code would do, using our beloved navigation paths: A -> B -> C (user-back) -> (code-back [line:18]) -> A The library provides a number of benefits, including: Automatic handling of fragment transactions; Correctly handling up and back by default; Default behaviors for animations and transitions However if if change the current Fragment via the Navigation Drawer and then press back the app always returns to the start Fragment of the Navigation Graph.
