1Android EmbeddedApp Sample
2===================================

4This simple app demonstrates how to embed a wearable app into a phone app.

6Introduction
7------------
8
9Wearable apps can be installed directly onto Android Wear devices during development, using either a direct ADB
10connection or ADB-over-Bluetooth. However, when releasing your app to end users, you must package your
11wearable APK inside of a traditional APK for distribution via a paired phone.
12
13When end users install this APK onto their phone, the wearable APK will be automatically detected, extracted, and pushed
14to their any paired wearable devices.
15
16This sample demonstrates how to properly package a wearable app for release in this manner. The wearable app is inside
17the `Wearable` directory, and the phone app (which will be used as a container for distribution) is the `Application`
18directory. There is nothing special about these apps, other than the `wearApp` dependency in the (host) phone app's
19`build.gradle` file:
20
21```groovy
22dependencies {
23 compile 'com.google.android.gms:play-services-wearable:6.5.+'
24 wearApp project(':Wearable')
25}
26```
27
28This dependency will automatically package the wearable APK during a **release build** (e.g. using the "Build > Generate
29Signed APK..." command in Android Studio). Note that this packaging is **not** performed for debug builds for
30performance reasons. During development, your wearable and phone apps must still be pushed individually to their
31respective devices using an ADB connection.
