Hello and thank you very much for getting back to me.
I am happy to say that the problem is resolved. I deleted the work I had done which had somehow introduced the errors and opened the files provided with the book purchase. Once I saw that everything was working as described, I deleted that project and began from the beginning once again. This time I had no errors. The eBook states the following:
Locate the projects folder for this chapter and open the TimeFighter app under starter. The first time you open the project, Android Studio takes a few minutes to set up your environment and update dependencies. (Android Apprentice, D. Bayliss & T. Blankenship, Page 48).
Perhaps whatever error I was experiencing was corrected when I followed those instructions.
