I am currently working on an Android book to teach people on how to develop for Android using a non-traditional language, such as Scala, JRuby, or Clojure.<p>My idea is to lead the reader from essentially zero knowledge of Android to developing a relatively simple application, learning Android basics along the way.<p>The twist, in comparison to other books, is that it would allow the reader to develop in a language of his or her choice. The book will include information on how to set up a build environment, using the available frameworks/tools for a given language, etc.<p>Would you be interested in such a book, and, if so, what sorts of information do you think ought to be included?<p>Also, since the book would guide the reader into building some sort of application, what kind of application would be good to create? I have in mind a shopping list: something relatively simple to implement, yet potentially useful.<p>Thank you for your help.
