In this chapter, we discussed what Android system programming is and the scope involved in system-level programming in this book. After that, we took an overview of the Android system architecture and talked about the layers that we will focus on in this book. We also discussed the virtual hardware platforms that we use in this book. In this book, we use the code from various third-party projects, so we also took a brief overview of each of them in this chapter. In the next chapter, we will start to learn about the development environment setup for Android system programming. This includes both development tools and the source code repository setup.

Overview of this book
Android system programming involves both hardware and software knowledge to work on system level programming. The developers need to use various techniques to debug the different components in the target devices. With all the challenges, you usually have a deep learning curve to master relevant knowledge in this area. This book will not only give you the key knowledge you need to understand Android system programming, but will also prepare you as you get hands-on with projects and gain debugging skills that you can use in your future projects.
You will start by exploring the basic setup of AOSP, and building and testing an emulator image. In the first project, you will learn how to customize and extend the Android emulator. Then you’ll move on to the real challenge—building your own Android system on VirtualBox. You’ll see how to debug the init process, resolve the bootloader issue, and enable various hardware interfaces. When you have a complete system, you will learn how to patch and upgrade it through recovery. Throughout the book, you will get to know useful tips on how to integrate and reuse existing open source projects such as LineageOS (CyanogenMod), Android-x86, Xposed, and GApps in your own system.
