Android EmbeddedApp Sample

This simple app demonstrates how to embed a wearable app into a phone app.


Wearable apps can be installed directly onto Android Wear devices during development, using either a direct ADB connection or ADB-over-Bluetooth. However, when releasing your app to end users, you must package your wearable APK inside of a traditional APK for distribution via a paired phone.

When end users install this APK onto their phone, the wearable APK will be automatically detected, extracted, and pushed to their any paired wearable devices.

This sample demonstrates how to properly package a wearable app for release in this manner. The wearable app is inside the Wearable directory, and the phone app (which will be used as a container for distribution) is the Application directory. There is nothing special about these apps, other than the wearApp dependency in the (host) phone app's build.gradle file:

dependencies {
    compile ''
    wearApp project(':Wearable')

This dependency will automatically package the wearable APK during a release build (e.g. using the “Build > Generate Signed APK...” command in Android Studio). Note that this packaging is not performed for debug builds for performance reasons. During development, your wearable and phone apps must still be pushed individually to their respective devices using an ADB connection.
