4.0 out of 5 stars
A book for beginners and tips for experts, August 31, 2010
This review is from: Sams Teach Yourself Android Application Development in 24 Hours (Sams Teach Yourself -- Hours) (Paperback)
Finally, I finished reading this book 24 hr is a misnomer, if you are thinking to finish the book in a day (it took me 13 days 2 hr a day cover to cover). One of the nice thing is the book is in Full Colour version these include screenshots, code and references to Eclipse (especially helpful if you are new with eclipse development). The book is easy to read, font and spacing were pleasing.
I should confess this is a beginner's book. You need some basic understanding of java and its concepts. The game the author picked was too basic for me, I wish I would have stated with this book months ago as it covers androids basic concepts and the first 6 chapters builds up the ground work for development on how to use eclipse and introduction to device debugging and logging( Eclipse DDMS, Android LogCat Logging).
A very good early introduction to debugging in chapter 2 right place before you get your hands dirty with coding, which i haven't seen any other books covering in that details. The author also mentions the reason they selected to use a particular android API or functionality at places and provide links for further reading.
There are also examples and exercises and although they are simple and primitive they give you the idea how to implement or use specific functionality and the solution for exercises are missing (it would have been helpful if there was a downloadable version on the website).Tips at some places are very useful and practical, some places it was an eye opener for an advance developer like me.
You will find this book useful and I'm sure it can be used as manual (not for expert android developer).

4.0 out of 5 stars
Complete, full of advice from real programmers, August 25, 2010
This review is from: Sams Teach Yourself Android Application Development in 24 Hours (Sams Teach Yourself -- Hours) (Paperback)
The first thing that hits you when you flip through the pages of this book is the color. The example screens, diagrams and tables really stand out. It's a delight to read a full color book and I'm thinking, why have I never come across more full color IT books?
The target audience are developers with a Java programming background who want to start Android development. And the book fulfills this promise very well.
The first couple of chapters are introductory, but aren't a drag to read (although the concepts of Activities, Intents and the manifest file are better explained in a book like "Hello, Android!" from the Pragmatic Programmers)
A second thing which really stuck out and is well worth mentioning are the "Did you know", "Watch out!" and "By the way" text boxes which really showed the authors have real programming experience with Android. Those little text boxes sometimes really contained little gems of information. These alone are worth reading every page of this book since you don't want to miss out on these.
The chapters are called "Hour 1..." and "Hour 2..." and are really targeted to be digested in an hour, max. I sometimes simply read a chapter in half an hour, without working out the examples in the development environment. I know, maybe not the way to go to really learn programming Android very well, but considering the time (we all have so little of) just reading a quick chapter was fulfilling for me anyway ;-)
Every chapter concludes with a Q&A section which was a bit tedious. The questions were very simple and the answers were right below the questions, so I skipped those sections further down the book. Apart from the Q&A section each chapter also included some exercises, which really are a challenge, because no 'answer' is given there. Just a task. I liked those!
A lot of Android books (or programming books in general) use a sample application which is enhanced throughout the whole book. This book is no different. However, where other books might focus on forms and list this book's example is a nice trivia game, which makes use of the camera, the network, social features and many other cool Android framework features.
The way the example program is set up and worked out is really the way you (or I in this case) would start fiddling around with Android. At some point it states: "You can copy the QuizSplashActivity five more times..." A very pragmatic approach, and again something programmers do daily. Maybe not the most elegant suggestion, but if you want to achieve something fast (learning Android) that's just the way I like.
Before you dive into a new chapter, a concept or screen layout a nice diagram is often presented first, which really helps in getting your brain in design / conceptual 'mode' (so to speak).
The majority of the Android concepts are covered really well. Shared preferences, context- and normal menus, dialogs, views, view switchers, image media, location based services, progress bars, communicating with a network server, creating home screen app widgets, and many more. Also 'development' activities like testing and developing for different devices and 'deployment' activities like placing your app in the Android market are present in the book.
The majority of the chapters have sample code, which you can download from a website. The examples all worked in my case. No problems there.
The author's are active bloggers on mobile application development and Android development in particular. If you don't buy the book you should definitely check out their blog (at [...]) and the mobile tuts website ([...]), with many of their contributions.
Advanced topics like OpenGL 2D/3D, the SQLite database, content providers and the various sensors, etc. are each described in half to a full page of text, but not more. I would have wanted to see a chapter on SQLite database and one on content providers though, since these are very common in Android apps, even for beginners.
Conclusion: I really liked the full color pages, the text boxes with invaluable information from real programmers and the digestibility of the chapters a real plus. Maybe some advanced features (like SQLite databases and content providers) could have been described in their own chapter, but then again, the target audience is the beginning Android developer. The book is very complete in the sense that it describes the whole process of setting up your dev environment, programming your app, testing it and deploying it on the Android market. I would really recommend this book for beginning Android developers. If you already read one or two Android books and consider yourself a mid-level to seasoned Android programmer don't buy the book. Maybe skim the pages and read the "Watch out!", "By the way" and "Did you know" text boxes ;-)

5.0 out of 5 stars
Best "quick-start" tutorial for Android 2.1 available, July 31, 2010
This review is from: Sams Teach Yourself Android Application Development in 24 Hours (Sams Teach Yourself -- Hours) (Paperback)
I bought this book a few days ago at SIGGRAPH - and it's great.
Android is a HUGE topic - it's utterly impossible for a single book to cover even a small portion of Android in depth.
But the authors have done a really admirable job of getting you started from scratch:
* Installing the Android IDE (Eclipse)
* Writing a simple "hello world", and executing it on the Android emulator
* Step-by-step chapters on building up a simple application that touches on key aspects of the Android
* Etc
The same authors have written another book (published by New Riders, instead of SAMS) with a lot more detail. But frankly, this is the better choice for a "first book".
You definitely ought to be at least familiar with Java before starting this book, just as it would be good to know a little Objective C before starting out on iPhone (and ESSENTIAL to know MORE than a little C++ before starting out on Nokia/Symbian). But, as the authors point out, Android can be a great way to learn Java.
I highly recommend Lauren Darcey's and Shane Conder's book.
