Past Saturday we held a Guru Session about Android Design Patterns and tools at Appsterdam. The topic is very interesting and so more than 15 people showed up with their laptops ready to learn more about it and, of course, talk about the topics and get their hands into some code to try it out.

I started talking about how to use one layout for all devices and how to adapt it, giving Chalk Ball as example (thanks to Matt for the photo) and moved over other topics as Master-Detail architecture, ActionBar and how to save time when testing on devices.

This time there was less bootstrapping new projects and more playing with the concepts, but all in all it was fun to run it and based on the comments, attendees learned new ideas and enjoyed it as well.
