Solution

  • If you checked the dependencies (com.android.support:appcompat-v7:27.1.1) and in the layout which starts by: androidx.coordinatorlayout It means you're still using Support Library dependencies but you are trying to use AndroidX CoordinatorLayout.

    Use Migrate to AndroidX from Refactor or, use Support Library CoordinatorLayout:

    <android.support.design.widget.CoordinatorLayout>
</android.support.design.widget.CoordinatorLayout>
