Android WatchFace Sample

A simple sample that demonstrates watch faces and complications for Wear 2.0.

Introduction

This sample demonstrates how to create watch faces for Wear.

The analog watch face covers best practices for Wear 2.0 including complications and a new configuration Activity for configuring both the watch face styles and the complications themselves. We recommend you reuse the configuration code and follow the UX patterns in your watch face's configuration activity. You can see a preview in the screenshots section of the README.

The analog watch face has three main classes:

  • AnalogComplicationWatchFaceService.java (watchface folder) - Renders the watch face and active complications.

  • AnalogComplicationConfigActivity.java (config folder) - Allows user to adjust watch face settings (arm and background colors) and watch face complications.

  • AnalogComplicationConfigData.java (models folder) - Populates the configuration screen in the previous step by returning a list of items. Each item represents something you can customize on the watch face. Items include a preview of the watch face (where you can pick your complications), marker color, background color, unread notifications, and background image complication. You can extend this and add your own.

We include several older watch faces to show best practices for Wear 1.0. If you are targeting older devices, you may want to review those watch faces (digital, opengl, and interactive).

The digital watch face includes a watch-side and phone-side configuration example.

This sample includes both a phone app and a wearable app.

Because watch face apps do not have a default Activity in their project, you will need to set your Configurations to "Do not launch Activity" for both the Wear and Application modules. If you are unsure how to do this, please review the "Run Starter project" section in the Google Watch Face Code Lab.

Steps to build in Android Studio

Once the project is open, edit run configurations -> General -> Launch Options -> Launch: Nothing this will allow runs.

Pre-requisites

  • Android SDK 28
