Automatic Autofill does not work after updating to AndroidX

[latsson]

Using the AutofillFramework example code works well. Using the RecyclerViewActivity, and clicking on the name field will show a box with my name that I can click to fill that field.

After days of trying to find why it doesn't work in my own app, I soon realised that the sample app isn't using AndroidX.

Just opening a fresh version of the AutofillFramework and migrating it to AndroidX using Android Studio will make the automatic autofill stop working. Long pressing the text field and pressing autofill still works, but what user will use that feature?

I have tested both on a Google Pixel running Android 10 and a OnePlus 8 Pro running Android 11.

Please let me know if I need to provide more information.
