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.

An overview of the Linux kernel

In Chapter 1, Understanding the Architecture, we learned how Android has been designed and built around the Linux kernel. One of the reasons to choose the Linux kernel was its unquestioned flexibility and the infinite possibilities to adjust it to any specific scenario and requirement. These are the features that have made Linux the most popular kernel in the embedded industry.

Linux kernel comes with a GPL license. This particular license allowed Google to contribute to the project since the early stages of Android. Google provided bug fixing and new features, helping Linux to overcome a few obstacles and limitations of the 2.6 version. In the beginning, Linux 2.6.32 was the most popular version for the most part of the Android device market. Nowadays, we see more and more devices shipping with the new 3.x versions.

The following screenshot shows the current build for the official Google Motorola Nexus 6, with kernel 3.10.40:
