Android multi-build is a very simple build-system built on top of the normal Android build-system tailored for those who need to maintain multiple Android builds.

• Near zero learning-curve.
• Build system 100% external to source-trees being built.
• Automatically generate changelogs for builds.
• Intelligent build: Dont build when there are no changes since last build.
• Automatic deployment of builds to hosting provider (FTP only for now).
• Automatic (and optional) Linaro toolchain support.
• Ability to non-destructively inject Linaro toolchain seamlessly into existing source-trees.
• Simple (very simple), declarative build format.
• Low error tolerance: Builds fails immediately, where the error occured.

• You already have one or several Android source-trees and you know how to build them.
• Existing trees are pre-primed, have vendor-binaries, etc and are ready to build.
• Tree is a CyanogenMod or similar AOSP-based tree which can be built with the normal Android build procedures.
• One tree is used for one device only. While re-using the same tree for multiple devices will produce good builds, the changelogs might include things they shouldn't.

1. Ensure you have one or more properly prepared Android source-trees.

2. Clone repo.

   $ git clone https://github.com/josteink/android_multi-build

3. Do a local branch to store your configs/customizations.

   $ git checkout -b production

4. Customize builds in run_all_builds.sh. Instructions and examples can be found in the file itself.

5. Customize target server in data/server.cfg.

6. Execute build.

   $ ./run_all_builds.sh

7. Wait for builds to finish.

Updates are done simply by pulling updates from github:

$ git pull origin master

Changes should then be merged into your production config.

Not making any promises, but these are things I might want to do in the future:

• Better documentation, in code and elsewhere.
• Extensibility (kernel variations, SSH/SCP upload).
• Email reports.
• Forum posting of builds.

Contributions welcome.
