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.

Creating over the air updates

Google provided plenty of developer tools to generate the different types of OTA. If you want to generate a Full Update OTA, the following two steps are required:

  1. Generate a ZIP file containing the full update files

  2. Generate the OTA package with all the necessary toolsets for the update

To generate the zip file containing the chosen target files, navigate to the root folder of the AOSP sources and run the following commands:

. build/ && lunch aosp-shamu
mkdir dist_output
make dist DIST_DIR=dist_output

If the process has been successful, we should have the zip file containing the target files in the directory dist_output. As an example, let's try listing the folder content with the following command:

ls -l dist_output/*target_files*

Now we should see a .zip file that will also have in its name the name of the target we are compiling for.

At this point, you only need to generate the OTA package containing all the necessary files for the update....
