Part 1: Dancing with the SDK

Join J. B. Rainsberger as he uses the principles of responsible design to build his first application for the Android platform. How does an advocate and teacher of evolutionary design and test-driven development approach an environment like Android? How does he explore the framework without becoming consumed by it? How exactly does one "do TDD" in Android? If you have these questions, then read this series, because they answer them.

Nice analysis of a "need to mock part of an object in a test" smell in @jbrains "Responsible Design for Android" book leanpub.com/ResponsibleDes…

In part 1 of the series, J. B. uses all his best tricks to explore the Android SDK without letting it swallow his code whole. You will find this useful especially if you have never built an Android application before.

You will see how the sausage is made. There is a lot of code. A lot.

@jbrains just finished reading "Responsible Design for Android" and loved it! I'm encouraged to build something using what I've learned.

Some people prefer browsing the code in an IDE, rather than reading code listings in a book. No problem: I've tagged every important snapshot of the code in a git repository hosted at github, so you can pick any snapshot of the book and browse that exact version of the codebase in seconds.

(While the book remains in draft mode, you'll probably find it easiest to read as a PDF, because it's really hard to make code samples look good in narrow formats. If you want to read the other formats, I recommend Landscape mode with single-column text. I'll figure out what to do when it comes time to pretty things up.)

This book lays the foundation for responsible design in Android application development. In subsequent books, J. B. will apply the patterns he's discovered here to ship more features. Read along and refine your understand of how to build a sustainable, extensible Android app.

I'm continuing to enjoy the Android book, keep it up! Reading your thought process for each decision and how you list possible tests and decide which ones to write has been valuable for me. I'll want to re-read those parts later to try and synthesize lessons
