Configurations for activity_main.xml must agree on the root element's ID. Missing ID: - layout @+id/drawer_layout: - layout-land

Question

Im using viewbinding, and i get this error when i build

Configurations for activity_main.xml must agree on the root element's ID.

Missing ID:
 - layout

@+id/drawer_layout:
 - layout-land

It says i need to have two different id for rootview. But i have different root for portrait layout and landscape layout. Like below. If i put same id to drawerlayout(landscape) and same id for constraintlayout(portrait) it creates problem in code. That to i wrote common code without checking orientation. How to get rid of this error, using <include id> or <merge> or anyother ways? (i dont know how these works exactly for my needs) without checking orientations in code blocks.

code

NavigationUI.setupActionBarWithNavController(this, navController, drawerLayout)

Answer 1

You're using a </androidx.constraintlayout.widget.ConstraintLayout> for the portrait and a </androidx.drawerlayout.widget.DrawerLayout> for the landscape orientation. Hence the error.. You can try running the app after wrapping the drawer layout in a constraint layout and giving each an identical id
