07/10/2019, 1:17 AMIs this the most elegant way to “go back two screens (i.e. two fragments)” if I have a single activity app using the navigation architecture component? Seems extremely strange, but works perfectly (calling this method twice…).
Copy code
fragmentManager?.popBackStack()
fragmentManager?.popBackStack()a
