The name doesn’t matter, It’s just a name for the android project. You can call it like MyFirstTest or something. Then you get a folder MyFirstTest inside the root of cocos2d-x, Open it.
You see Android - Classes - Resources. Put your classes in side the classes folder, and for the resources the same .
Then you have to open the Android.mk file (if you use version 0.13, it should be at) MyFirstTest/Android/jni. Open it and add your classes you made to it.
LOCAL_SRC_FILES := helloworld/main.cpp ../../Classes/AppDelegate.cpp ../../Classes/Player/Player.cpp
If you have done that, then you should open cygwin and go to the folder. cd /cygdrive/c/cocos2d-x/MyFirstTest/Android (ENTER) and then ./build_native.sh
And if anything goes wrong you will see it there Hope that gives you a start and answer to your question
