下面详细介绍一下用ndk r9版本编译cocos2d x 2.0.4可能会遇到的各个坑吧。
错误提示1：

make: *** [obj/local/armeabi/objs-debug/cocosdenshion_static/simpleaudioengine.o] error 1
解决方法：把simpleaudioengine.cpp第159行注释掉
在文件夹cocosdenshion/android中找到simpleaudioengine.cpp文件，定位到第159行，将其注释掉如下：
//logd(devicemodel);
再次用cygwin terminal软件运行build_native.sh，又出现新的提示错误。

错误提示解读：warning我们就不管了，先只看error，openslengine.cpp文件324行error。
解决方法：把cocos2d-2.0-x-2.0.4\cocosdenshion\android\opensl文件夹下的openslengine.cpp文件
324行注释掉 /*logd(errorinfo);*/
再次运行build_native.sh，又提示错误。

这次轮到simpleaudioengineopensl.cpp文件第41行。
解决方法：把cocos2d-2.0-x-2.0.4\cocosdenshion\android\opensl文件夹下的simpleaudioengineopensl.cpp文件第41行注释掉：
/* logd(errorinfo);*/
再次运行build_native.sh。又提示错误，warning我们就不管了，先只看error。
错误提示4：

make: leaving directory '/cygdrive/e/cocos2d-2.0-x-2.0.4/cocos2d-2.0-x-2.0.4/testa/proj.android'
解决方法：这次我们在application.mk文件后面添加下面代码：
app_cppflags += -wno-error=format-security
再次运行build_native.sh，然后一切就顺利了！我把so文件(libgame.so)在eclipse里面导入android项目，并编译成apk文件，测试成功。
至此，ndk r9版本就可以用build_native.sh编译成so文件(libgame.so)，
已经在真机上测试cocos2d x的hello world成功。
如果再有其他报错应该不是ndk r9本身的原因，建议考虑ndk_root是否设置，或者权限的问题，
或者是项目的代码问题（有一些vc++允许通过的，这里会有细微的差异）。
如果第一次尝试做交叉编译的同学，建议不要用自己写的classes代码编译，
可以考虑用官方的helloworld，这样可以减少困扰。
