Android System Programming

By: Roger Ye, 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.

Building recovery for x86vbox

After analyzing the workflow and key elements in the recovery source code, we can now start to build it for our x86vbox device.

The changes to support the recovery build include the changes to x86vbox devices and the changes to recovery and newinstaller.

Building configuration

Before we look at the changes for this chapter, let's look at the configuration files first. As usual, we have a manifest file for each chapter. We make changes for this chapter based on the source code of Chapter 11, Enabling VirtualBox-Specific Hardware Interfaces. The following are the projects that we are going to change:
