title: Custom watch face for Android Wear
body: <p>A few apps have come out already for Android Wear that contain custom watch faces (<a href="https://play.google.com/store/apps/details?id=com.bytemesoftware.wear.faces.binary" rel="noreferrer">like this one</a>). They are not just apps that simply display a watch face; they are full-fledged faces that are selectable when long-pressing the home screen of the watch. I can't find any documentation on how to set up your app to provide a custom face. How do you configure your app to provide a face?</p>
