Chapter 1. Understanding the Architecture

In this chapter, the user will learn about Android hardware and software architecture. We will provide an overview on the Android Compatibility Definition Document to properly understand what we need in order to create a fully compliant and certified device.

The user will learn about the Android Application Framework (AAF), the two different Android runtime systems—Dalvik, and ART, and a collection on Google-provided system libraries.

The user will have a first hands-on moment, setting up and running Android Compatibility Test Suite. We will test together an existing certified device and we will take the first step on the path towards the creation of a certified device.
