This is only partially correct. Yes, the files needed to build the finished project are in Github, but it does not include the file "candy_coded_icon.png" which is used in the step for changing the default launcher icon. I can just use an arbitrary image for this step, though it would be nice to know what resolution the source image should be. For now, I'll just try something fairly hi-res and hope that Android Studio can create all the required icon densities. I'm mentioning this mainly for the benefit of other students who will eventually encounter the same issue.
