eclipse ”Open the Java build path property page of project“

问题:
myeclipse 提示”Open the Java build path property page of project“
参考:
http://answers.opencv.org/question/5672/i-cant-use-opencv-in-android/
分析：
参考的地址中如下：
“Tutorial-3 is Java application with native C++ part. Native part was built successfully. There are some problems with Java. There are several reasons for that:
You use incompatible Android SDK version. There were several incompatible changes in Android SDK, that breaks OpenCV build. Update OpenCV up to 2.4.3.2 and Android SDK up to the latest version” 这个是因为opencv是c++的sdk要在java中用要导入包含底层依赖的库，这样自己的问题应该是引用的jar包中使用了httpclient的包没有引用引起的，添加后问题解决。
