I’ve created a custom view that is using data binding.
When I use the custom view in a layout it works perfectly in a device, but I cannot manage to have a working layout preview.
I always get the following exception: ClassNotFoundException: androidx.databinding.DataBinderMapperImpl
any idea how to solve it?

I’ve already tried clean/rebuild/invalidate caches etc.

Usually this error means that you have an error in your layout file.
