原文：http://transing.xyz/2015/07/23/build-protobuf-with-ndk-under-windows/

git clone https://github.com/google/protobuf.git
git checkout v3.0.0-alpha-3.1

在protobuf文件夹下建立build.bat，内容如下

set PATH=%PATH%;E:\devel\android-ndk-r9d
ndk-build.cmd
pause

在protobuf文件夹下新建jni文件夹，然后新建Android.mk文件，里面内容如如下(这里的内容主要是参考src/Makefile.am文件得到的)

LOCAL_C_INCLUDES:= \
    $(LOCAL_PATH)/../src \
    $(LOCAL_PATH)/../

LOCAL_LDLIBS := -L$(SYSROOT)/usr/lib -lz
LOCAL_SHARED_LIBRARIES:= 
LOCAL_MODULE:= protobuf
LOCAL_MODULE_TAGS := optional

include $(BUILD_SHARED_LIBRARY)

再建立Application.mk文件，内容如下

APP_MODULES      := protobuf
APP_PLATFORM     := android-9
APP_ABI          := armeabi-v7a
APP_STL          := gnustl_static
APP_OPTIM        := release
 
APP_CPPFLAGS     := -fexceptions -frtti

过程中会提示缺少config.h和pbconfig.h，这两个文件是跑configure后才生成，从linux编译一次protobuf生成后拷贝到windows就好了。

或者自己手动建立，config.h的内容如下
