Alpha WatchFace Sample (Kotlin)

Demonstrates watch faces using the new androidX alpha libraries (Kotlin).

Introduction

With the release of the androidX alpha watch face libraries (late 2020), Wear OS has simplified watch face development.

This sample gives you an early preview of how you can simplify your development with the new 100% Kotlin libraries.

Steps to build in Android Studio

Because a watch face only contains a service, that is, there is no Activity, you first need to turn off the launch setting that opens an Activity on your device.

To do that (and once the project is open) go to Run -> Edit Configurations. Select the app module and the General tab. In the Launch Options, change Launch: to Nothing. This will allow you to successfully install the watch face on the Wear device.

When installed, you will need to select the watch face in the watch face picker, i.e., the watch face will not launch on its own like a regular app.
