Databinding errors after migrating to AndroidX

Question

I'm getting a lot of errors with data binding errors after migrating to AndroidX (Refactor > Migrate to AndroidX).

error: cannot find symbol
      @Nullable ViewGroup root, boolean attachToRoot, @Nullable DataBindingComponent component) {
                                                                ^
  symbol:   class DataBindingComponent
  location: class ActivityInfoBinding

I'm using Android Studio 3.2 Beta 2

I love android databinding itself, the code is so clean, but the tools make it so hard to work with :( — jakub, Jul 06 '18 at 12:31
Did you try to rebuild and / or Invalidate Cache & Restart? There are newer version available, for example: androidx.appcompat:appcompat:1.0.0-rc02 you should update these. Can you show the whole class in which the error that you show occurs? — 476rick, Sep 12 '18 at 11:45
@qbait yesterday found out, that there is an `androidx` data-binding compiler available (despite still experimental): https://stackoverflow.com/a/52489036/549372 — Martin Zeitler, Sep 26 '18 at 02:49

Updating to latest Android Studio and re-importing the project fixed my issue.

To fix this issue I had to update all class names on layout files.

From:

<android.support.design.widget.CoordinatorLayout
<android.support.v7.widget.RecyclerView
...

to:

<androidx.core.widget.NestedScrollView
<androidx.coordinatorlayout.widget.CoordinatorLayout
...

After that, the data binding errors where gone.

I ran the migration tool, but it didn't fixed the class names on layout xmls, sad!
