How do I stop AppBarConfiguration from switching the hamburger icon into the back arrow?

How do I get the hamburger icon back for the navigation drawer? the AppBarConfiguration changes it into a back arrow, why is that?

This is my code below:

  @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    context = this;

    init_v3();
    BottomNavigationView navView = findViewById(R.id.nav_view);
    // Passing each menu ID as a set of Ids because each
    // menu should be considered as top level destinations.
    AppBarConfiguration appBarConfiguration = new AppBarConfiguration.Builder(R.id.home, R.id.nav_tasks)
            .build();
    NavController navController = Navigation.findNavController(this, R.id.nav_host_fragment);
    NavigationUI.setupActionBarWithNavController(this, navController, appBarConfiguration);
    NavigationUI.setupWithNavController(navView, navController);

}

You should add all the fragments that you don't want the up/back button to show up in the appBarConfiguration

In your example, this up/back button won't show up in R.id.nav_tasks & R.id.home fragments as you already added them. >> if you have more fragments, then add them into the below separating between them with comma.

And to show up the Drawer burger icon, you need to call setOpenableLayout(drawerLayout)

DrawerLayout drawerLayout = findViewById(R.id.drawer_layout);

AppBarConfiguration appBarConfiguration = new AppBarConfiguration.Builder(
                                         R.id.home,  
                                         R.id.nav_tasks)
                                         .setOpenableLayout(drawerLayout)
                                         .build();
