注：本文适用于cocos2d-x 3.1使用ant或eclipse编译的方式，其它cocos2d-x版本请注意修改相关引用lib；若用Android Studio，可参考思路，具体实现大为不同。
在用cocos2d-x做Android开发时，若用项目默认配置，每次clean后都会需要再次编译coco2d-x的库，十分耗时。
这里给出一个直接使用静态库而不用每次都编译源码的方法:
1\ 首先找到一个cocos2d-x的测试项目（如cpp_test)，进行一次编译。完成后，在proj.android/obj/local目录下可以找到中间过程中生成的所有静态库文件。
把这些静态库文件（带上ABI目录）复制出来，放到一个新的目录（如：cclib）中。
2\ 在cclib中创Android.mk文件，文件内容见代码附1.
3\ 定义环境变量 CC_SRC_ROOT 为cocos2d源码目录（即cocos与external的上层目录）
在编译你的项目时依赖cclib，同时去掉依赖cocos2d目录下的Android.mk
！如果修改了cocos2d-x源文件，请重新编译静态库文件。
