AOSP Android build project
***************************

Android is multi-configuration Jenkins project. We need to combine repo plugin with matrix plugin.

Important options are:

-  Use custom child workspace in Advanced Project Options
-  Definition of the correct repo manifest as shown in the follow picture
-  Definition of build matrix in order to have the output of all the artifacts

Execution shell needs to take in account the variant for clean the project and for the output directory.

::

         #!/bin/bash -xe

         OUT_DIR=out_$BuildVariant
         export OUT_DIR

         source build/envsetup.sh
         lunch rtc700m-$BuildVariant

         make clean

         # export WITHOUT_HOST_CLANG=true
         CPUS=$(getconf _NPROCESSORS_ONLN)
         echo "Build on " $CPUS " cores machine"
         make -j $CPUS
