Jetpack conditional navigation

Issue

I want to change my start navigation fragment based on a condition. My start fragment could be fragment one or two. Is there a way to implement it?

Solution

Check out this question and its solution // Also added Java code here

Just converted Kotlin code to Java

NavHostFragment navHostFragment = (NavHostFragment) getSupportFragmentManager().findFragmentById(R.id.home_nav_fragment);  // Hostfragment
NavInflater inflater = navHostFragment.getNavController().getNavInflater();
NavGraph graph = inflater.inflate(R.navigation.nav_main);
graph.setDefaultArguments(getIntent().getExtras());
graph.setStartDestination(R.id.fragment1);

navHostFragment.getNavController().setGraph(graph);
navHostFragment.getNavController().getGraph().setDefaultArguments(getIntent().getExtras());

NavigationView navigationView = findViewById(R.id.navigationView);
NavigationUI.setupWithNavController(navigationView, navHostFragment.getNavController());
