Learning Embedded Android N Programming

By: Ivan Morgillo

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.

Summary

In this chapter, we learned what we are going to need to create a certified Android device. We saw the Android Compatibility Definition Document and we learned how to design a system to match the Android architecture. We had an overview of the two different runtime systems: Dalvik and ART and their main differences.

We had a full immersion into Android device testing, we learned how to run CTS automated tests and CTS manual tests on a already certified device.

The next chapter will be very hands-on. We will learn how to retrieve Android source code and we will understand the code structure and organization.
