Chapter 1 Android Programming HELP

I am getting this theme error when trying to run my device. I am not sure where it is coming from or what I am doing wrong. I am using groovy language. here is my current code in the comments:

It looks like you have an issue with AppCompat (which we talk about in Chapter 15). You don’t need to know all the inner workings there right now.

The most straightforward fix is to create a new project and double/triple check that the template that you use is the “Empty Views Activity”, not the “Empty Activity” template. Android Studio has changed the naming of stuff in the past year or so, so our book is a little out of date.
