Android OpenCV 遇到的错误：Unresolved inclusion

在配置Android OpenCV时，cpp或者c文件出现如下问题：

Unresolved inclusion:****

Symbol '***' could not be resolved

解决办法：

1.Eclipse右键-->Properties

2.选择C/C++ General

3.选择Pathsand Symbols

4.选择GNUC++ 项

5.在Include标签下添加如下几项内容：

${NDKROOT}/platforms/android-9/arch-arm/usr/include

${NDKROOT}/sources/cxx-stl/gnu-libstdc++/4.6/include

${NDKROOT}/sources/cxx-stl/gnu-libstdc++/4.6/libs/armeabi-v7a/include

${ProjDirPath}/../../sdk/native/jni/include

6.要确认定义了NDKROOT和ProjDirPath，在C/C++ Build -->Environment来进行设置。
