Migration to androidX - can't import/find androidx.databinding.DatabindingUtil

The problem was that I tried to do it manually. So I upgraded to Android Studio 3.2 RC 2. After that I used the migrate function of Android Studio.

For the migrate function in Android Studio go to > Refactor > Migrate to AndroidX...

When Android Studio gives you errors after that, try to Rebuild or maybe use > File > Invalidate Cache & Restart.

As @cchcc pointed out, don't forget to add this to your gradle.properties:

android.useAndroidX=true
android.enableJetifier=true

I was missing the

android {
    dataBinding {
        enabled = true
    }
}

1. Be sure you are using Android Studio 3.2 RC 2

2. Add 2 lines below in gradle.properties file

   android.useAndroidX=true
   android.enableJetifier=true
