Answer 1

Android Navigation Components handle fragments transaction and back stack automatically and that's the whole point behind this component.

In your fragment:

findNavController().navigate(id)

This id could be either action id or destination id.

I recommend navigating by action id.

Actions are arrows connecting two destinations together. Destination is another word for a fragment.

If you need to access your navigation inside Activity:

findNavController(containerId).navigate(id)

constainerId = the id of FragmentContainerView inside your XML.
