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。

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。
