Overview of this book

Android Wear Projects is your opportunity to step into the exciting new world of Android Wear app development. This book will help you to master the skills in Android Wear programming and give you a complete insight on wear app development. You will create five different Android Wear apps just like the most popular Android Wear apps. You will create a To-do list, a city maps app, a Wear messenger, Wear fitness tracker and Watch face. While you create these apps you will learn to create custom notifications, receive voice inputs in notifications, add pages to notifications and stack notifications.

Collecting Wear sensors' data

Collecting sensor data from Wear devices needs a mechanism, and the Wearable DataLayer API, which is part of the Google Play services, plays a major role in the communication process. We will explore the communication process in later lessons but in this chapter, we need to receive the sensor data in the mobile app. We have created the project, which already has a mobile module and the simple plain old Hello World boilerplate code. We will work on the mobile module once we set our data sending mechanism from the Wear app. Let's start with the step count sensor in the services package of the Wear module and go to the WearStepService class. We have built this service to fire a notification and listen to the step counter data. Now, with the help of GoogleApiClient and the Wear Messaging API, we need to send the data to the mobile app.

In the WearStepService class, instantiate GoogleApiClient in the global scope of the class:

GoogleApiClient mGoogleApiClient;
