How to build an Android and OLPC OS dual-boot image for XO-4.

Ingredients

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

Method

$ repo init -u git://dev.laptop.org/users/ben/android_manifest -b android-4.3.1-xo4
$ repo sync
  • if you would like to include google services, download developer package from here gapps. See also Google Apps
  • The Google Apps packages are NOT SUPPORTED in any way by OLPC.
$ tar -zxvf gapps.tar.gz
$ mv gapps vendor/olpc/xo4/
  • start the build:
$ . build/envsetup.sh
$ lunch 14
$ make installclean && make -j8 && make userdatatarball
  • (the 14 means to build engineer version ... use command "lunch" to list all the build options, Android/Building/Variants)
  • (the -j8 means to run eight concurrent threads of build ... the number of threads should be chosen according to how many CPU cores your build environment has access to.)
  • install the android-tools-fsutils package or ensure you have simg2img tools in your /usr/bin/ simg2img
  • create zd file:

Android only image

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

Combine Android with Sugar

  • ensure you have a copy of the OLPC OS Linux, Sugar and Gnome build file, e.g. 32014o4.zd,
$ cd vendor/olpc/xo4/sugar-combiner
$ make
$ sudo ./mkzd.sh

Alternative Method

To merge an already published Android build with an already published OLPC OS derived build:

Using an Android build before 2015 on XO-4 produced in 2015 requires a special kernel, contact OLPC for details.

Source code

source code for building Android is a combination of 4 parts.

  • You can also download kernel image form latest kernel if you don't want to change kernel
