Android Studio version: 4.0 AGP version: 4.0.0

Description: The autocomplete experience for generated binding classes in Android Studio 4.0 (and possibly other versions) could be better. The search term "Binding" does not offer suggestions for any binding classes.

Steps to reproduce:

Create a new project using the empty activity template
Enable View Binding in the app/build.gradle file with buildFeatures.viewBinding = true
In MainActivity.kt, begin declaring a new variable binding:
When specifying the type for binding, start typing "Binding"
Notice that ActivityMainBinding is not one of the suggested classes in the autocomplete popup window. The same can be said for the search term "Main".

Thanks for the report. This is a caching issue that's hard to pin down. We're investigating a rollback of caching behavior if that's possible, but people have reported much better behavior using 4.1, if that's available to you.

Accepted by da...@google.com.

Sorry, I was wrong in my assessment earlier. This is not a caching issue. I misunderstood the initial bug since I was worrying about reports of view binding classes not resolving.

I can reproduce this issue easily, although I'm not yet sure what I can do about it (we don't write the logic behind autocompletes, we just provide answers to the underlying IDE framework when they ask us questions). I'll schedule a bit of time later to take a look, after getting through a few other priorities.

Marked as fixed.

Thank you for the suggestion. This behavior should start rolling out in AS4.2 Canary 4 and after.
