Overview

You've developed a killer app for one mobile device—now it's time to maximize your intellectual investment and develop for the full spectrum of mobile platforms and devices. With Multimobile Development, you'll learn how to quickly retool between the iPhone and Android platforms and broaden the interest and audience of your app, without working with burdensome and error-prone compatibility layers and toolkits.

Multimobile Development takes you, the developer, through the same mobile software development project on both platforms, learning the differences between and the relative strengths and weaknesses of each platform as you go. No magic intermediate layers of obfuscation—by the time you get to the end you'll be an expert at developing for any of the major smartphone platforms using each vendor's preferred toolset and approach.
