I see… you are trying to set new destination from your fragment, that’s fine. I do not know how your Fragment’s ViewModel are being instantied, but if you want to create a communication between Activity and Fragment your ViewModel need to be instantiated like:

ViewModelProviders.of(getActivity(), factory).get(

Then this way your fragment will use its activity’s viewmodel instance instead of its own.

I do not see your Fragment’s ViewModel implementation, but I think it can be the problem, because you are trying to change the destination from the Fragment and observing state changes in your activity.
