大家好，我是 android 新手，我试图通过 web 服务从 android 将一些数据保存在 sql server 中。我在 android 和 web 服务中创建了一个示例应用程序。我收到一个异常，但我无法在 java 中解决异常。这是我正在使用的代码。
这是我正在使用的网络服务。它工作正常。

这是 MainActivity.java 文件。在这里我遇到了一个例外

我得到了这个例外
java.lang.ClassCastException: org.ksoap2.SoapFault
在这条线上
// Get the SoapResult from the envelope body.
SoapObject result = (SoapObject)envelope.bodyIn;
