If you meet this error when trying the build your android code:
make: Entering directory `/bsp/Project_Name'
build/core/main.mk:7: You are not using bash - builds will fail
build/core/main.mk:8: *** Stop. Stop.
make: Leaving directory `/bsp/Project_Name'
Previous version of Android seems not to check if the "sh" is bash.
Just change to point to /bin/bash instead of /bin/sh by:
sudo dpkg-reconfigure dash (and answer no)
sudo rm /bin/sh
sudo ln -s /bin/bash /bin/sh
