== Each time you want to build replicant 2.2 SDK ==
Open a new shell and do:
{{{
cd ~/replicant-2.2
 ../bin/repo sync
source build/envsetup.sh
export ANDROID_JAVA_HOME=$JAVA_HOME
make -j$(echo "$(grep 'processor' /proc/cpuinfo | wc -l ) + 1" | bc) sdk  #uses arguments like -j9 to speed up build in case of multi-core cpu
}}}
Note that we don't run the lunch command
