--------------------编程问答-------------------- 找不到类，基本是缺少包含该类的jar包，往这方面去找吧 --------------------编程问答--------------------
首先，排除INTERNET权限缺失的问题；
其次，将ksoap2-android.jar（jar包名称可能不同）复制到项目源目录libs目录中（如果libs不存在择手动信新建一个文件夹），然后设置项目Build Path，在Libraries页签中添加ksoap2-android.jar。
再者：方法一，在order and export标签页，将ksoap2-android.jar项勾上。
方法二，在source标签页点击add folder，选中libs或者自己新建的lib文件夹。
（这样做的目的是：使jar包包含在apk文件中，可以发现在bin目录下生成的*.apk文件比之前大了） --------------------编程问答-------------------- 这种情况应该是缺少jar包，或者是jar包的版本不对；打开jar包，看有没有缺少的类。
补充：Java , J2ME
