How do I use Android View Binding in a library module?-CodePudding

I think I know the answer to this, but...

I enabled View Binding in a library module. Fine. I then take that .AAR and use it in another app, where I've not enabled View Binding. When I run that app and start an Activity from the library, I get

java.lang.NoClassDefFoundError: Failed resolution of: Landroidx/viewbinding/ViewBinding;

If I then enable view binding in the app, everything works fine. It seems like I should be able to use view binding in a library without having to also enable it in the app.

Is the necessary class getting Proguarded away, perhaps?

check this androidx/viewbinding/ViewBinding has in apk

I figured that when I enabled View Binding, it was probably adding a library that I wasn't seeing. I discovered I could add

implementation 'androidx.databinding:viewbinding:7.1.2'

instead of enabling View Binding, which solved my problem.
