Acknowledgments

I would like to acknowledge the excellent staff at Apress who managed to get this book completed on time through multiple delays and reworking of the original title. You've made the process much less frightening for a first-time author than I expected.

A special thanks goes to coordinating editors Mary Tobin and Corbin Collins, and to Tom Welsh, the lead editor.

I'd also like to thank Frank Pohlmann for convincing me to do this project in the first place.

Thank you to the technical reviewer, Justin Grammens, for a keen set of eyes and helpful comments.

A big thank you to Robbie Matthews, who has become one of the primary contributors to the SL4A project and provided help when things didn't make sense.

Thanks also to the folks at TechSmith, and Betsy Weber in particular, for their fantastic Snagit product, without which the screenshots would have been so much harder.

Final thanks go to my son Micah Ferrill for his help with the Python code.
