Hey Jeff,
I’m looking through what you have here and I’m trying to figure out what’s going on.
The first thing I want to hit are those five functions from PennyDropDao. All five are on pages 118 and 119 when we first create the abstract class. Are these the functions you’re referencing here?
The issue with the Game class looks familiar from my initial development work, though I do not remember what caused that specific problem. Could you share what your Game class looks like? And an offer: if you wanted to upload your work to GitHub or something similar, I’d be willing to troubleshoot things that way with you. I want to make sure you can get as much as possible out of the book.
For reference, you’re right on point with the *.java files being generated. 
Also, you’re correct on the Database Inspector being moved in Arctic Fox. I’m really starting to dislike this new Android Studio update.
Let me know on your Game class (and if you want to put the whole project out somewhere I can access it) and we’ll go from there!
