I was at Fry's Electronics and came across these 2 books. Unlocking Android: A Developer's Guide Pro Android Would you guys/gals recommend any of those 2 books, or any other books for a beginner? Currently I don't have any fancy apps in mind, but I do have some engineering calculation apps that I want to make. In other words, I don't want an advanced 3D gaming book, just a good book to get me started. Any suggestions would be greatly appreciated.
