我是 android 和 Web 服务（基于 java 肥皂）的初学者。我试图做的是从 Web 服务请求一种方法。它不需要任何参数进行初始测试并在 logcat 或简单的文本视图。最初它给了我身份验证错误，提供了对 Web 服务的基本 http 身份验证，因为它需要相同，然后
当我再次运行程序时，它开始在我调用的这一行之后抛出异常：
httpTransport.call(SOAP_ACTION, envelope);
我得到的错误是：
04-26 10:10:12.945: I/System.out(322): org.xmlpull.v1.XmlPullParserException: 意外类型（位置：TEXT
enter code here04-26 10:10:12.945: I/System.out(322): ------=_Part_56...@5:13 in java.io.InputStreamReader@40580270)
我用谷歌搜索了很多，甚至搜索了 stack over flow 中的几乎所有问题。但没有找到任何有用的解决方案，因此再次提出这个问题。请仔细阅读代码，让我知道我哪里出错了
