Just recently started android application development. Seems to be quite complicated yet interesting. I was lucky enough to find a 50% off coupon for Barnes & Noble and was able to purchase my first dummy book. My rating is a 4 out 5 stars, leaving one star out for those who are not familiar with java coding; you’ll need another dummy book for that. All in all the book is quite informative with step-by-step app instructions & ways to throw them on the android market.
