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 w

Answer 1

I've solved this problem this way:

    @Override
public void onActivityResult() { //inside my fragment that started activity for result
        model.navigateToResults = true; //set flag, that navigation should be performed
}

and then

    @Override
public void onResume() { //inside fragment that started activity for result
    super.onResume();

    if(model.navigateToResults){
        model.navigateToResults = false;
        navController.navigate(R.id.action_startFragment_to_resultsFragment);
    }
}

not sure, if this is not a terrible hack, but it worked for me. FramgentManager state is restored at this point (onResume) and no problems with navigation occur.
