Chapter 3. Creating, Debugging, and Packaging Wearable Apps

This chapter will provide you with the background and understanding of how you can build and package your own apps for Android Wear. We will learn how we can draw our own Android watch face using Google's official API, and also to present information within the watch area.

We will learn how to create a custom class that inherits from Google's latest watch face service API that will enable us to respond to watch face events to handle screen updates, draw watch face elements, and respond to changes between the interactive and ambient modes.
