I, too recommend the books by Mark Murphy. You can get the uptodate PDFs/mobi/epub versions at commonsware.com. Real books on Android (or any other fast moving technology) tend to be outdated when they reach the bookstore. For the price of one book you get three (the fourth about the ndk is due late april) with a one year update. Mark does more than one update in a year.
