Book Review: Android User Interface Development 111

Posted by samzenpus from the read-all-about-it dept.
RickJWagner writes "So you want to be an Android developer? If you're like me, you've probably been wanting to learn how to program a mobile device, but just haven't found the time to master Objective-C. So now that Android is here, all of us garden-variety Java coders can jump on the bandwagon and start slinging apps out, right? Well, it turns out there's a little more to it than that. This book can make the trail from everyday Java code slinger to best-selling Android app writer a little more plausible." Read below for the rest of Rick's review.

ISBN A good resource for Android developers who aren't already UI experts.
summary 7/10
The book does not teach Android development. For that, there are other books and the Android SDK documentation, which I found adequate for my uses so far. This book emphasizes teaching Android User Interface development, which is something I would not have had much of a clue about without the book. (The Java and XML-based configuration of Android is easy enough for a back-end Java coder like myself, but I've never been a web-design and layout guy. Or fat-client layout and design guy for that matter, either.) That's the sweet spot for this book.

Android newbies do get an introductory chapter that guides the reader through setting up the SDK and writing a quick first app. After that, the book starts to take a serious UI bent, and that's o.k. because that's where the book's intended to go. The earliest chapters cover UI-centric matters like asking the user a question and processing the answer that is returned. List selections are explained (i.e. single-select button choices versus multi-select). Functional features like adding a header or a footer are explained.

The middle chapters cover pragmatic issues like producing an image gallery, handling date/time inputs, and validating user inputs. Layouts in Android are explained, which will be somewhat familiar to Java Swing developers. I had an interest in learning how animation works (don't we all dream of writing the next viral-selling game?), this is explained as well.

The final chapters deal with styling (i.e. how to change the way a button looks) and themes. It's very important that your application 'feels' like it should, and this is given adequate coverage in the book. I'm sure a back-end coder like myself would botch this part horribly without guidance, so I can appreciate the reason the book emphasizes these things.

The book is written in Packt's 'Cookbook' style. If you haven't seen one of these before, the book is largely cut up into sections covering some general idea. Within the section you'll find headings for the topics "Time for Action", "What Just Happened" and "Have a Go, Hero". "Time for Action" is a series of instructions that spell out exactly what to do for a sample scenario. "What Just Happened" follows up with an explanation of why the reader was asked to execute the instructions. "Have a Go, Hero" is a section challenging the reader to extend the spoon-fed instructions by implementing a next-step challenge. This style of writing emphasizes hands-on knowledge transfer without a lot of verbose theory, so it'll be good for readers who like to learn as they code. Contrast this to books that have a lengthy section of text explaining all the details of some topic, followed by a monolithic code blob towards the end of the chapter-- this book is not written that way.

The sample code that's available on Packt's site is clean and easy to understand. It follows the same structure as the sample code you'd find in the SDK, so if you're brand new to Android development you might start with the SDK teachings and then extend it with the book as soon as you're ready. I thought the examples the book presented were almost all reasonably relevant. The author did a good job of keeping the exercises presented throughout the book well contained, so you're never asked to code too much stuff at one time. I like that, as it lets you read the book without having to set aside a huge block of time at once to see the results of your coding efforts.

So who is this book good for? I'd say it's a good resource for Android developers who aren't already UI experts. I'm not saying it's good for Android newbies who need to learn the basics of Android programming, because there's just too little introductory material for that. But if you can already hack something together, and want it to be appealing to someone besides yourself, this book can help.

      • objective-c is not the same as java

        Objective C is the result of small-talk and C having unprotected sex . But small-talk expressive power is much greater than the expressive power of java and in C you can code anything that is possible on your system as you have a raw acces to that system. So I must concede that objective-c must be a really powerful language. But it syntax is so awful that I always get sick before I really take the time to get use to it.

      • You'll find the radically different syntax a blessing rather than a curse if you plan on flitting between languages on a regular basis. If you work with two almost identical but subtly different languages, the small differences with catch you out more often than you'd like. When you work with Objective-C and Java at the same time, the differences are substantial, so you end up putting more effort into learning them.

        That's my experience, anyway.

    Saying you don't have time to learn Objective-C is ridiculous. If you know Java, It takes half a day to learn Objective-C. The time consuming part of learning any new technology/platform is learning the frameworks. Cocoa and Cocoa Touch are huge and use design patterns that many coders do not already know. Fortunately, the design patterns are used everywhere, and they are used consistently. Once you understand and recognize the patterns, there is no more productive and flexible framework on the planet.

    Frankly, learning the design patterns will make you a better programmer no matter what platform you choose. It's worth it just to advance your computer science knowledge.

          Don't forget that with the new Objective-C 2.0, reference counting is a thing of the past thanks to auto-released objects, and properties which are automagically created for you. Objective-C may not be the easiest OO language, but it sure is easier than ever (and I am an Android fan BTW).

          • Don't forget that with the new Objective-C 2.0, reference counting is a thing of the past thanks to auto-released objects

            autorelease is a method in cocoa and has nothing to do with ObjectiveC 2.0. Notably, it has nothing to do with making reference counting a thing of the past –it is in fact part of the ref counting system – it adds the object to a set of objects to have their reference counts decremented when the current stack unwinds back to the next autorelease pool drain.

            References are pointers without an explicit need to dereference them. Every reference is internally a pointer.

            Pointers "point" to a memory location. References "reference" an object.

            Internally they are identical. Both contain a natural word-sized number that references a memory location.

            These are very different concepts and I don't care to write a tutorial on the subject here on /.

            I'll take the time to write a tutorial. Pointers and references are internally identical. References as a language construct do not permit address arithmetic, while C pointers do. References are not immutable, they can be reassigned.

            Suffice it to say that pointers provide a mechanism for code to corrupt (whether intentionality or not) memory while references (being immutable) preclude this.

            I don't think immutable means what you think it does.

              References are NOT internally pointers. Just run a java app in a debugger and step through the code. Look at each reference created. The first reference created will have a reference id of something like 16, the second will be 17, and so on. These are simply "references" used to lookup the object, not address locations in memory. In C you can take a pointer and add 1 to it to address the next byte in memory, but you cannot do this with a reference. That's a VERY bi

I see that the author of this review has a blog on which he's reviewed two (maybe more?) of the Packt books, but it's possible that that's because he is active in the field and found genuine value in the book.

        I'm still more likely to buy the Pragmatic one, but this I felt was a good review: it focused on what was in the book: cookbook style, mainly focused on UI (rather than the SDK), etc. These are all very valuable thi

        • The review is a shill if there's a great deal of info on the contents of the book, but nothing on the quality of those contents. Did the reviewer actually follow any of the instructions? Do the programs work or have bugs? Does the book make the issues clearer or more confusing? And when it comes time to build a real solution to a complex problem, how well did the book prepare you?

        • If it gets the salient points that you're interested in across, then it sounds like it doesn't matter (for you) whether it was a shill posting or not. When I read these, the basic facts are definitely useful - but I'm also looking for an honest evaluation of the book's content. In this case (and in the case of all Packt reviews I've seen here in the last 1-2 years) we are given details about the content of the book; but told very little about the quality of that content.

  • So my only choices for smartphone development are Objective C or Java? Seems like a lose-lose situation to me. Why can't I use native C or C++ on either of them?

      On Android you can use the NDK.

      On the iPhone you are perfectly free to use Objective-C++, or C, and mix in calls to the Objective-C framework.

      Between the two life is probably easier for the C/C++ programmer on the ObjC side.

      Oh and there's also mono for the iPhone if you prefer C#.

      You can use native C for iPhone development. Objective-C is a strict superset of C.

      You can use native C/C++ for both of them, except in certain places. The UI layer, for instance, has to be done using the native language on either platform (objc or java).

    • Or Python or Perl on Android

      There's a nice 20% project called Android-Scripting that lets you use scripting languages through an interpreter. Not exactly fast and lacks some features, but it makes it easy to get started with basic Android development in a language you're more familiar with.

      You can on some phones, like Nokia's N900, Symbian phones. And Windows Mobile smartphones, I think.

      On the N900, you even get a standard *nix environment, with libc and shell and X and a package manager that lets you install pretty much whatever you want.

    • Jython runs on the Andriod. This means you can use that to run python code. Cool hack.

      I wonder if you could use the Andriod apis? I can't see why not.

  • The author's blog [wordpress.com] is a good chance to check out his writing, coverage of the kinds of development he's done, and depth of technical expertise. It's also worth mentioning that he is the designer of the EodSQL [java.net] open-source (LGPL) O/R bridge for Java.

    Disclosure: The author is my son, so yeah - proud Dad talking, but seriously check his work out for yourself if you (like me) think the review leaves something to be desired. Personally I'm still reading the book, so can't evaluate yet...

  • Ah....the old Java sucks, no it doesn't, C is better, no C++ is, garbage collection is for newbies, I can write some trivial program in that beats your program written in , blah blah blah blah blah. I've seen enough of these threads on /. to know that nothing useful will come of them. Including, especially, this comment. Pro-tip. Does your code meet required specifications? If yes, whodafuckcares.
