This repository contains a set of individual Android Studio projects to help you get started writing Wear OS apps and watch faces.
Read below for a description of each sample.
AlwaysOnKotlin (Kotlin) - Demonstrates keeping the app visible in ambient mode. Note: While this is valuable for some specific use cases, most use cases won't need this, because when the watch goes into ambient mode (and shows watch face), if the user interacts with the watch again within several minutes, it will bring the app back up when it transitions out of ambient mode. Guide
DataLayer (Java) - Demonstrates communicating via the data layer between the watch and the phone. Guide
RuntimePermissionsWear (Java) - Demonstrates requesting permissions not only on a Wear OS device and a mobile device, but also across devices, e.g., request permissions on a mobile device from your wear device and the other way around. Note: It does require you having both the Wear and Mobile version of the app installed on both devices. Guide
WatchFace (Java) - Shows a full implementation of multiple watch faces, complications, and settings (edit watch faces appearance). Also includes implementation of data providers, so developers can share their data to be displayed in complications on any watch face (without writing a watch face). Watch face guide, Data Provider Guide
WatchFaceAlphaKotlin (Kotlin) - Demos the new alpha AndroidX Watch Face APIs. The analog watch face in the sample is powered by a full Room database and uses the new settings APIs (among many other new APIs). Keep in mind that the APIs can change as the alpha proceeds. This version uses alpha4 and will have some additional updates for the next versions.
WearDrawers (Java) - Demonstrates Navigation (Top) and Action (Bottom) Drawers, part of Material Design for Wear. Guide
WearOAuth (Java) - Demonstrates how developers can authenticate a user on their Wear OS app via the user's mobile/phone device without requiring a mobile app (Wear OS companion app handles the request on the mobile side). The sample uses OAuth. Guide
WearSpeakerSample (Kotlin) - Demonstrates audio recording and playback if the wearable device has a speaker. Guide
