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.

Enabling Wi-Fi on the Android Emulator

In the last three chapters, we have explored ways to customize and extend the Android emulator. In this chapter, we will pursue this topic to add Wi-Fi support in the Android emulator. If you are a developer using the Android emulator, you may notice that there is only data connection in the Android emulator. Some applications may be aware of the connection type and exhibit different behaviors according to the connection type. In this case, you cannot use an emulator to test your applications. In this chapter, we will cover the following topics:

  • Introducing Wi-Fi architecture in Android
  • Extending the x86emu device to support Wi-Fi connections
  • Testing a Wi-Fi connection on the x86emu device

The topics in this chapter are at an advanced level. We will analyze the Wi-Fi source code at the beginning of the chapter to help understand the Wi-Fi architecture. I recommend that you...
