Safe args allows you to get rid of code like this when passing values between destinations: And, instead, replace it with code that has generated setters and getters. 2. Android Navigation between fragments using backstack and static fabric pattern Example First of all, we need to add our first Fragment at the beginning, we should do it in the onCreate() method of our Activity: You can also use the convenience method Navigation.createNavigateOnClickListener(@IdRes destId: int, bundle: Bundle). There are a few ways to get a NavController object associated with your NavHostFragment. That's the basic idea. Otherwise you will get an IllegalStateException.
