I was engaged by Lonely Planet to build Android versions of their popular iOS Phrasebook application, shortly after the first version of the Developer SDK for Android was released by Google.
Lonely Planet had already created an iOS version of these apps and the content to support them.
In order to not duplicate effort, the approach I took was to build a skeleton Android application and a build system that would produce multiple signed APKs, one for each language content. The system reuses the iOS content.
