So as I said I was going to, this is the thread for my progress on the book, Hello, Android. When applicable, I fully intend on publishing the completed apps (after sufficient testing on my own device, mind you) on the Marketplace, much to the chagrin of a certain lurking individual, I believe. In any event, I thought I'd go ahead and post something that seems to be a rather large issue at the offset (only now popping up in chapter three): It would seem that a common problem in each book I've read thus far (either because it's a change in the Android platform, or the IDE I'm using is the issue, or something else, perhaps...) is that at one point or another, there's an issue with a resource being unable to be resolved. That being said, a Google search has found that the solution to this is the following: Remove the initial Code: Import android.R; Line from the beginning of your files and rebuild. This'll make sense if and when you read the book.
