What readers said about this and earlier editions: Best money I've spent in a long time. Bravo JonPM Excellent! I have no doubt that this will become, or already is, the definitive guide to writing apps for any Android device. Amazon Customer This was a book that I now use as a constant reference and have found it a mine of information. Brilliantly written and presented. Excellent book. Just what I was looking for. I will not now be able to think of developing an app without this book at my side. This book does an excellent job of explaining most things. Buying this book was money well spent. Richard J. Garcia A real must-have manual for B4A. Paul Holthuizen The only one book available with good coverage of this programming language ALEXEI BOGDANOV good reference book for an excellent product. Richard Linder I find it very useful right next to my computer when programming. Very helpful when needed to look something up or to study when not near a computer. Amazon Customer It is very comprehensive and useful for Android programming. LIm, Bongcheon
