In Chapter 7, Tailoring Your Personal Android System, you learned how to add the final personal touch to your custom Android system. You customized both the application layer and the system layer: new menus, new apps, and new daemons.
In this chapter, we are going even further: we are going outside the smartphone, connecting to external microcontrollers, sensors, and different devices. We will see how our whole world could be connected and interactive with Android.
You will learn about Android ADK and Arduino, and how Google is filling our lives with Android-oriented devices: from Chromecast devices to Android Auto, from smart watches to Internet of Things.
