Android System Programming

By: Roger Ye, Shen Liu

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.

The AOSP build environment and the Android emulator build

In order to create our own Android system, we have to set up the AOSP build environment and build our own AOSP target for the Android emulator. Since Android is under rapid development, the build process and environment setup can change from time to time. You can always refer to Google's website for the latest information,

While the Google website and other sources can give general guidelines and procedures about the AOSP build, in this section we will look specifically at how to build AOSP for Android emulator image for API level 25.

Since we want to set up a build environment for API level 25, you can refer to the table of AOSP...
