我正在尝试构建此代码：https://github.com/ayuso2013/face-recognition
我已成功安装OpenCV库，例如“Open CV Library”“JavaCV-Bin”
我可以成功编译应用程序，但是当我尝试运行它时，我得到以下错误：

我可以看到这一行
02-24 19:30:00.777: E/AndroidRuntime(13937): Caused by: java.lang.ClassNotFoundException: Didn't find class "org.opencv.javacv.facerecognition.FdActivity" on path: /data/app/org.opencv.javacv.facerecognition-2.apk
但我确定文件FdActivity.class位于src / org / opencv / javacv / facerecognition /
我做错了什么？
