Ignoring navigate() call: FragmentManager has already saved its state

Question

I'm using navigation in MainActivity, then I start SecondActivity (for result). After finish of SecondActivity I would like to continue with navigation in MainActivity, but FragmentManager has saved his state already.

On Navigation.findNavController(view).navigate(R.id.action_next, bundle) I receive log message:

Ignoring navigate() call: FragmentManager has already saved its state

How I can continue in navigation?

Answer 1

You must always call super.onActivityResult() in your Activity's onActivityResult. That is what:

1. Unlocks Fragments so they can do fragment transactions (i.e., avoid the state is already saved errors)

2. Dispatches onActivityResult callbacks to Fragments that called startActivityForResult.
