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.

Preparing the host system

To successfully compile our custom kernel, we need a properly configured host system. The requirements are similar to those we satisfied to build the whole Android system in the previous chapter:

  • Ubuntu

  • Linux kernel source code

  • Toolchain

  • Fastboot

Ubuntu needs a bit of love to accomplish this task: we need to install the ncurses-dev package:

$ sudo apt-get install ncurses-dev

Once we have all the required tools installed, we can start configuring the environment variables we need. These variables are used during the cross-compilation and can be set via the console. Fire up your trusted Terminal and launch the following commands:

$ export PATH=<toolchain-path>/arm-eabi-4.8/bin:$PATH
$ export ARCH=arm
$ export SUBARCH=arm
$ export CROSS_COMPILE=arm-eabi-
