SUCCESS! I got selenium running with a little bit of code. It basically takes over a browser window and allows you to give the browser input through python code. We will soon be able to scroll to the bottom of a friends page and load the html of said page to get the id's of someone's friends. I will implement it in our project tomorrow, but we are back on track to collect data and I am happy.
After some setbacks and a long search we found the best SDK for our app. Vuforia is a cross platform SDK that has the necessary computer vision-based image recognition needed for our app. Vuforia offers two options for developing, you can either write a single native app or use a Unity base package. Both methods would allow you to reach the most users across the widest range of smartphones and tablets but unity has the built in rendering engine.
Found a couple bugs as I was about to push a large new feature. Expect prediction and rankings to be working sometime Friday. Cheers.
