CHAPTER 4

Android Wear Demand

By Michael Hahn, January 2015

The Demand context is one of the core functions for Android Wear. A demand is displayed as a large icon, typically

when you swipe a displayed suggestion (notiﬁcation). You tap on an icon to perform the desired demand.

When new email arrives for example, you swipe to the left to scroll through the demand icons, such as open, reply,

and archive. You can create custom icons for your app as well. This section explains how to code your own wearable

demand that handles a voice reply.

4.1 First Android Wear Demand

If you have not already done so, Create a Project. The new project wizard in Android Studio creates a project with

two main activities, one for the handheld device and another for the wearable. To create your ﬁrst demand, add code

in the handheld activity only, located in the “mobile” branch of the project hierarchy. The software preinstalled on a

wearable device or emulator handles the task of displaying notiﬁcations and handling demands on the wearable side.

4.1.1 Add Build Dependencies

Add build dependencies for the wearable support package to the build.gradle (Module:mobile) ﬁle in Gradle Scripts

folder, if necessary.

dependencies {

compile fileTree(dir: ’libs’, include: [’

.jar’])

wearApp project(’:wear’)

compile ’com.android.support:appcompat-v7:21.+’

compile ’com.google.android.gms:play-services:6.5.+’

}
