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.

Integrating Houdini to the x86emu device

The goal of this chapter is to support Houdini ARM binary translation in Android emulator. After we have an overview of the internals of Native Bridge, which is the foundation of the Houdini library, we can work on Houdini support for our x86emu device.

Since the Houdini library is an Intel proprietary library, it is not available publicly. For those people who want to add Houdini to a new device, such as an Android emulator that is not supported by Intel, the only possible way is to copy the Houdini library from a supported device and add it to the unsupported device.

Fortunately, the open source project Android-x86 provides basic support for Houdini to any Intel devices, which we can use as a reference in this book. In this chapter, we will add Houdini to an Android emulator based on the Android-x86 project.
