Because I wrote more than one cocos2d-x extension so I found some code can be moved out as a common codebase.

Here is my extensions which refer to this common base:

• https://github.com/stubma/cocos2dx-anim
• https://github.com/stubma/cocos2dx-json
• https://github.com/stubma/cocos2dx-wisound
• https://github.com/stubma/cocos2dx-db

cocos2dx-common project refers cocos2d-x project. You must clone cocos2d-x repository to a folder named "cocos2d-x", and then clone cocos2dx-common in the same parent folder.

There is a test project in test folder, it supports iOS and android. If you want other platform, do it yourself.

For iOS, just drag cocos2dx-common project into your project. For Android, just import cocos2dx-common module. If not clear, refer to demo code.
