a book that one can have no regret in his technical library

The overview seemed complete. Not knowing Android before, it is difficult to know for sure yet, but I rely on the many articles and websites that I could study elsewhere. The explanations are clear and precise.

Also note that unlike many books (supposedly) techniques, which use this method to produce impressive paved with less effort, you have little (or no) illustrations, screenshots and endless listings unnecessary, which produce a lot of pages, but with an almost derisory information density.

As the title says: to have on hand if you embark on the discovery of this universe.

PS: There is a French version of this book, which I guess is the translation of the book commented here, given the similarity of the cover illustration. Having no problem with technical English, I preferred the original version, having been disappointed by a significant number of French versions of reference books.

PPS: why I did not give it 5 stars? Because perfection does not exist in this world;)
