Error inflating class after migration to androidx

Question

I made a migration to Androidx but after the migration, I'm getting the following error:

 Caused by: android.view.InflateException: Binary XML file line #12: Binary XML file line #2: Error inflating class android.support.design.widget.CoordinatorLayout
 Caused by: android.view.InflateException: Binary XML file line #2: Error inflating class android.support.design.widget.CoordinatorLayout

I studied all the resources and migrated to Androidx, but I still have a lot of problems. Can someone help me? I will post the sections of the code below.

Answer 1

You are likely to have a reference to android.support.design.widget.CoordinatorLayout in some of your xml layout files.

Press CTRL + SHIFT + F or go to Edit/Find/Find in Path and just search for android.support.design.widget.CoordinatorLayout and replace it with androidx.coordinatorlayout.widget.CoordinatorLayout.

You may use CTRL + SHIFT + R or Edit/Find/Replace in Path instead to replace all matches at once.

Answer 2

in XML file, replace

androidx.appcompat.widget.RecyclerView

with:

androidx.recyclerview.widget.RecyclerView
