Hey Darryl!
As you’ve seen, I’ve called out some updates to the code in the past, but I haven’t checked on the code with more recent versions of Android Studio. While the concepts in the book are still applicable, I’m not surprised that you’re running into setup/config issues as you go along.
Can you share the specific error you’re facing after you add the dataBinding = true line to your project? That’ll help me figure out what’s going on.
