Android.mk: Some issues : cocos2d-x v3.2 project

Hi…

I was looking at Android.mk in my project.
I use v3.2

I saw that the intial lines says

$(call import-add-path,$(LOCAL_PATH)/…/…/cocos2d)
$(call import-add-path,$(LOCAL_PATH)/…/…/cocos2d/external)
$(call import-add-path,$(LOCAL_PATH)/…/…/cocos2d/cocos)

Why there isn’t anything like
$(call import-add-path,$(LOCAL_PATH)/…/…/cocos2d/extensions)

If I add this line, then do I need to uncomment the following lines: which are already there inside Android.mk but commented? Or better to say that do I really need statements below if I have that above line added?

LOCAL_WHOLE_STATIC_LIBRARIES += cocos_extension_static
$(call import-module,extensions)

Thanks…
