Embedded Android

Embedded Android is for Developers wanting to create embedded systems based on Android and for those wanting to port Android to new hardware, or creating a custom development environment. Hackers and moders will also find this an indispensible guide to how Android works.

Looking to port Android to other platforms such as embedded devices? This hands-on book shows you how Android works and how you can adapt it to fit your needs. You’ll delve into Android’s architecture and learn how to navigate its source code, modify its various components, and create your own version of Android for your particular device. You’ll also discover how Android differs from its Linux roots. If you’re experienced with embedded systems development and have a good handle on Linux, this book helps you mold Android to hardware platforms other than mobile devices. Learn about Android’s development model and the hardware you need to run it Get a quick primer on Android internals, including the Linux kernel and Dalvik virtual machine Set up and explore the AOSP without hardware, using a functional emulator image Understand Android’s non-recursive build system, and learn how to make your own modifications Use evaluation boards to prototype your embedded Android system Examine the native user-space, including the root filesystem layout, the adb tool, and Android’s command line Discover how to interact with—and customize—the Android Framework

The First Practical, Hands-On Guide to Embedded System Programming for Android Today, embedded systems programming is a more valuable discipline than ever, driven by fast-growing, new fields such as wearable technology and the Internet of Things. In this concise guide, Roger Ye teaches all the skills you’ll need to write the efficient embedded code necessary to make tomorrow’s Android devices work. The first title in Addison-Wesley’s new Android™ Deep Dive series for intermediate and expert Android developers, Embedded Programming with Android™ draws on Roger Ye’s extensive experience with advanced projects in telecommunications and mobile devices. Step by step, he guides you through building a system with all the key components Android hardware developers must deliver to manufacturing. By the time you’re done, you’ll have the key programming, compiler, and debugging skills you’ll need for real-world projects. First, Ye introduces the essentials of bare-metal programming: creating assembly language code that runs directly on hardware. Then, building on this knowledge, he shows how to use C to create hardware interfaces for booting a Linux kernel with the popular U-Boot bootloader. Finally, he walks you through using filesystem images to boot Android and learning to build customized ROMs to support any new Android device. Throughout, Ye provides extensive downloadable code you can run, explore, and adapt. You will Build a complete virtualized environment for embedded development Understand the workflow of a modern embedded systems project Develop assembly programs, create binary images, and load and run them in the Android emulator Learn what it takes to bring up a bootloader and operating system Move from assembler to C, and explore Android’s goldfish hardware interfaces Program serial ports, interrupt controllers, real time clocks, and NAND flash controllers Integrate C runtime libraries Support exception handling and timing Use U-Boot to boot the kernel via NOR or NAND flash processes Gain in-depth knowledge for porting U-Boot to new environments Integrate U-Boot and a Linux kernel into an AOSP and CyanogenMod source tree Create your own Android ROM on a virtual Android device

Create the perfectly customized system by unleashing the power of Android OS on your embedded device About This Book Understand the system architecture and how the source code is organized Explore the power of Android and customize the build system Build a fully customized Android version as per your requirements Who This Book Is For If you are a Java programmer who wants to customize, build, and deploy your own Android version using embedded programming, then this book is for you. What You Will Learn Master Android architecture and system design Obtain source code and understand the modular organization Customize and build your first system image for the Android emulator Level up and build your own Android system for a real-world device Use Android as a home automation and entertainment system Tailor your system with optimizations and add-ons Reach for the stars: look at the Internet of Things, entertainment, and domotics In Detail 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. Style and approach This step-by-step guide is packed with various real-world examples to help you create a fully customized Android system with the most useful features available.
