用安卓中jython包开发了获取教务处课表的小程序，出错为NoClassDefFoundError

代码如下：public class CourseScrawler {
public static int[][] getCourseArray(String stuID, String pwd) {
PythonInterpreter interp = new PythonInterpreter();
interp.execfile("src/course-scrawler.py"); //引入Python文件
PyFunction func = (PyFunction)interp.get("getCourseArray",
PyFunction.class);
PyObject pyobj = func.__call__(new PyString(stuID),
new PyString(pwd)); //给Python函数传参
int[][] courseArray = (int[][])pyobj.__tojava__(int[][].class); //将返回结果转换为Java数据类型
return courseArray;

}

出错如下：
