cocos2dx 提高 build_native.sh 编译速度

进入生成的obj文件夹看看 proj.android\obj\local\armeabi

发现是编译时生成的静态库动态库，我们不想每次生成一个新跨平台项目的时候都全部重新编译一次，可以重复利用这些类库
解决方案是在cocos2d-x-2.1.5目录下新建prebuild目录，把proj.android\obj\local\armeabi下（libcocos2dcpp.so就不用了）的类库都copy到prebuild，增加一个类似这样的Android.mk

来试一下COCOS2DX自带的demo，F:\cocos2d-x\cocos2d-x-2.1.5\samples\Cpp\TestCpp
TestCpp和pro.android/jni里都有Android.mk，打开修改尾部代码
TestCpp下的Android.mk


#$(call import-module,CocosDenshion/android)
#$(call import-module,external/Box2D)
#$(call import-module,external/chipmunk)
#$(call import-module,cocos2dx)
#$(call import-module,extensions)
$(call import-module,prebuild)
proj.android/jni里的Android.mk



$(call import-module,samples/Cpp/TestCpp)
#$(call import-module,cocos2dx/platform/third_party/android/prebuilt/libcurl)
#$(call import-module,cocos2dx)
#$(call import-module,CocosDenshion/android)
#$(call import-module,extensions)
#$(call import-module,external/Box2D)
#$(call import-module,external/chipmunk)
$(call import-module,prebuild)
cygwin进入到F:\cocos2d-x\cocos2d-x-2.1.5\samples\Cpp\TestCpp\proj.android

./build_native.sh
发现编译快多了，只是编译了Classes和jni部分，其他都利旧。现在可以导入到eclipse里运行TestCpp了么么哒
