Another Four-to-Free Guarantee Update

I have just released Version 1.1 of The Busy Coder’s Guide to Android Development under a Creative Commons Attribution Non-Commercial Share Alike 3.0 License, per the Four-to-Free Guarantee, as that title has sold 4,000 copies since its release.

Again, this version of this book is out of date in many ways, so be careful when relying upon it.

There should be a few more updates to this book similarly released in upcoming months, reflecting the fact that the book didn’t exactly “sell like hotcakes” when it was first published, so it doesn’t take many incremental sales for a new version to qualify for the Four-to-Free Guarantee.

If you have any questions about the book, please join the cw-android Google Group and post there!
