A basic example of reproducing Instagram info bars behaviour. A list header floats over the list's items and remains visible at the edge of the screen until it is replaced by the next list header

I created a prototype of the UBER app for Android in order to demonstrate what is possible using Proto.io. This project was a massive undertaking as my goal was to simulate the user experience of what it would be like to order 4 different UBER cars in San Francisco. I plan on doing a full "behind the scenes" article on my website about the challenges I faced along the way simulating the UBER app in Proto.io. Special thanks to the awesome team at Proto.io for all of their tireless assistance along the way!
