Android/Building

How to build an Android image for XO-4.

We provide in this directory changes to the Android 4.3.1 source so that Android can be built for the XO-4 laptop, and then merged with an OLPC OS build to create a dual-boot image.

Ingredients

• a well connected development system,
• about 20 GB of download capability,

Method

• follow the "Downloading the Source" guide to install Repo,
• use Repo to download the Android source,

$ repo init -u https://android.googlesource.com/platform/manifest -b android-4.3.1_r1
$ repo sync

• in the same working directory, expand our file xo4-android-source-release-20131220.tar.gz and merge the changes,
• start the build:

$ . build/envsetup.sh
$ lunch 13
$ make -j8

• ensure you have a copy of the OLPC OS Linux, Sugar and Gnome build file, e.g. 32013o4.zd,
• prepare a .zd file for the XO-4:

$ cd vendor/olpc/xo4/mkzd
$ ./mkzd.sh
