    This script is mainy used for building tests built-in with cocos2d-x.

    Usage: %prog [options] [cpp-empty-test|cpp-tests|lua-empty-test|lua-tests|cpp|lua|all]

    If you are new to cocos2d-x, I recommend you start with cpp-empty-test, lua-empty-test.

    You can combine these targets like this:

    python android-build.py -p 10 cpp-empty-test lua-empty-test


    Note: You should install ant to generate apk while building the andriod tests. But it is optional. You can generate apk with eclipse.
