In this chapter, we explored the features and key concepts of the Android Wear platform; we discussed about the Android Wear architecture; and then we moved on to look at how to configure our Android environment, setting up the Android SDK and AVD, before finally taking a look at how to build our simple Android wearable app.

In the next chapter, we will cover the features of Android notifications and explore the different ways that we can send notifications between the handheld device and the Android wearable to create basic and custom notifications. We will learn how we can use the Android voice capabilities to allow the user to respond to notification messages by using just their voice, and how we can use a method called page stacking to receive multiple notifications.
