In my workshops, often the greatest challenge for designers is converting their existing Android designs to the new Material Design approach—making the interface both simpler and more visually rich than their corresponding Android 4.x designs, as well as laying out the “happy path” for the customers (using Floating Action Button or FAB, as one of the tools). The following sticky note wireframes demonstrate my quick take on converting the Android 4.x TripAdvisor app into Material Design using $1 Prototype methodology — perfect for prototyping Android Material Designs.
