Design Tools - Closing the Gap Between Designer and Developer

Alternative Title: What to expect as a Android Developer from Designer for Design Handoffs

The talk is about all the tooling used by the speaker in designing UI and Interactions at Fabulous and how the handover happened between design and dev team to ensure best quality app implementation. It also talks about some of the common obstacles in efficient communication between designer and developer and how to address them for better communication.

This is mainly aimed as a sharing to the developers on what/how a usual designer used for designing, and what are some of the tools that can help in better communication between designer and developer.
