What readers are saying about Hello, Android

This is a most excellent book: very well written, easy to read, and fun. In addition, any of Android’s quirks are explained along with just the right amount of detail to ensure quality programming principles are followed. Anthony Stevens Founder and CTO, PocketJourney and Top 20 Winner of Google AndroidCompetition Ed Burnette covers an impressive amount of ground in a nicely compact book while retaining the popular Pragmatic style. For the material on 2D and 3D graphics alone, this is worthy of a spot in any Android developer’s library. Mark Murphy Founder, CommonsWare I remember when I first started to work with Android; it was like a huge maze. With this book, the introduction would have been muchless painful. I am convinced that by reading this book new Android programmers will have an easier start. Gabor Paller Senior Software Architect, OnRelay, Ltd.
