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.

Setting up the toolchain

The toolchain is the set of all the tools needed to effectively compile a specific software to a binary version, enabling the user to run it. In our specific domain, the toolchain allows us to create a system image ready to be flashed to our Android device. The interesting part is that the toolchain allows us to create a system image for an architecture that is different from our current one: odds are that we are using an x86 system and we want to create a system image targeting an ARM (Advanced RISC Machine) device. Compiling software targeting an architecture different from the one on our host system is called cross-compilation.

The Internet offers a couple of handy solutions for this task—we can use the standard toolchain, available with the AOSP (Android Open Source Project) or we can use an alternative, very popular toolchain, the Linaro toolchain. Both toolchains will do the job—compile every single C/C++ file for the ARM architecture.

As usual, even the toolchain...
