Overview of this book

Take a deep dive into the Android build system and its customization with Learning Embedded Android Programming, written to help you master the steep learning curve of working with embedded Android. Start by exploring the basics of Android OS, discover Google’s “repo” system, and discover how to retrieve AOSP source code. You'll then find out to set up the build environment and the first AOSP system. Next, learn how to customize the boot sequence with a new animation, and use an Android “kitchen” to “cook” your custom ROM. By the end of the book, you'll be able to build customized Android open source projects by developing your own set of features.

Chapter 3. Set up and Build – the Emulator Way

In the previous chapter, we learned how to retrieve the source code and we had an overview of the folder's structure. We now know how the branching model works and how to contribute to the project. This is an important topic, because Android is an open source prot, but it's managed in a very different way compared to other popular open source projects.

In this chapter, we will set up the whole environment to get ready to build our first Android system and flash it to a real target. Our efforts will be focused to create a fully-working version for the official Android emulator.

The user will learn how to use tools such as adb and fastboot, two of the most important tools that Google provides.
