Yesterday I pushed the first bit of beerscan related code to the github repository: https://github.com/johanv/Beerscan. It is code for a stupid Android app, wich doesn't do anything more than showing the camera input to the screen. You have to start somewhere, don't you.
I will soon post a howto for setting up the development environment and for compiling the app on this blog.
Although the functionality is minimal, there is already a bug: when you turn around your phone, the orientation of the captured images is wrong.
