Hello Kirk Knoernschild,
I am a Java developer and since this year an Android developer. I'm really interested in developing good software and apps and I know that to achieve my goal I need to design better my apps. Is your book also useful for an Android developer, can I use the concepts explained in your book to realize better Android apps?
The modularity patterns aren't tied to a specific language or platform. Since Android uses Java as the language and supports JAR files, the concepts should translate nicely to Android.
However, I have not thought deeply about applying the patterns to Android, so certain adjustments may need to be made. But that's the intent of a pattern. Tailor it to your context and language (aka. idioms). If you do apply the patterns on Android, I'm very interested in hearing about your journey. Contact me on Twitter to share stories. Thank you.
Visit the book's website at modularity.kirkk.com where you can review all 18 patterns and download an excerpt of the book. There is also a mobile web application available that you can take with you wherever you go.
