Component used: Navigation
Version used: 1.0.0-alpha05
Devices/Android versions reproduced on:

While navigating from a fragment to another, both containing different Toolbars, that are being setup using NavigationUI.setupWithNavController(toolbar, navController, navigationDrawer) the fragments are being leaked because the implementation just adds new ToolbarOnNavigatedListener which retains the toolbar instance from the fragments but it isn't removed next time a different toolbar is setup. Also, there is no way to remove this listeners manually because they are not returned at setup time.

public static void setupWithNavController(@NonNull Toolbar toolbar,
            @NonNull final NavController navController,
            @Nullable final DrawerLayout drawerLayout) {
        navController.addOnNavigatedListener(
                new ToolbarOnNavigatedListener(toolbar, drawerLayout));
        toolbar.setNavigationOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                navigateUp(drawerLayout, navController);
            }
        });
    }
