Based on the documentation from http://android-rebuilds.beuc.net/, I setup fully-automated recipes to rebuild the Android SDK, including setting up the reference distro environment and dependencies, with help from Docker.

For instance, to rebuild a complete Android SDK 6.0.1, checkout

https://gitlab.com/android-rebuilds/auto/tree/master/sdk-6.0.1

and type:

   make

That's all !
