The Android operating system works on phones that combine a camera, Web browser, e-mail, GPS, and mapping tool into a single accessible pocket-sized unit, and can function on computers, as well. Aimed at visual learners and packed with hundreds of screen shots, this guide brings Flash developers up to speed on the necessary factors to take into account when developing for this touch-based, mobile platform. Experienced Flash developer Julian Dolce escorts you through the process of creating applications for the Android OS using the Flash CS5 development platform and informs you of best practices to try as well as common pitfalls to avoid.
GDNet Staff Review:
From version 2.2 (Froyo) on, Android devices support both Flash, both as web content and as standalone apps using the AIR runtime. Android Development with Flash is a guide to the latter, specifically building Android apps with Flash that look and act like they've been built with native tools. While the AIR packager for Android is a fairly simple affair that can be done with command-line tools or with a "wizard" interface entirely within Flash, that's not the sum-total of standalone Android-AIR development. It's quite simple to convert a web-based Flash game into a standalone Android game, but you'll need to do a bit more work if you want your game to be more than a web game running outside a browser. For example, you might want to store progress in a local database on the phone. You might want to add location awareness. You certainly might want to respond to "user just turned the phone sideways" or "the phone just rung, so pause yourself" events.
Android Development with Flash is formatted as a series of dozens of 2-4 page mini-tutorials. And these range from the thoroughly elementary "how to install the Android SDK" to the more advanced stuff like "How to access location services". Apart from the first couple of chapters, nothing is a prerequisite of anything else, so if you're a rank amateur who's building a database-centric app, you can skip right to the database tutorials immediately following getting your first app compiled and running.
There's no book-spanning take home game project. There's no class library. This isn't that kind of book. While it has some good introductory material for beginners, if you're expecting to start at page 1 and be an Android AIR development expert by page 300, this book won't do it. This book is intended for people who already have a project in mind, are somewhat experienced, and who just need something to speed through the difficult parts.
And of course, that leads to the question "why do I need this book?" After all, there are innumerable documents and web forums out there that'll tell you the events you need to listen to in order to gracefully shut down when the user presses the Home button. And while those resources do exist, they're pretty-much all over the place. Thus-far, I haven't found anything that lumps all of the "how to be a first class application" into a single place.
As for the cons, the book is pretty screenshot-happy. Every mini-tutorial is accompanied by at least four screenshots. Even stuff as simple as "How to stop a playing sound" is accompanied with screenshots. While I understand that they're trying to make things obvious, I don't think I need four pictures of Flash's ActionScript text-editor to explain that SoundChannel.stop() is the function that stops a playing sound. While such a model is perfect for something like Photoshop that's nothing but user-interface, with a code-centric tool, I'd prefer more tips and fewer pictures.
The last 50 pages of the book consist of an AS3 class reference. While a similar reference is no further away than my F1 key while in Flash, sometimes it is handy to have it printed out.
