在我的应用程序中，我在该登录页面中创建了登录页面我输入了用户名和密码详细信息，并且当我尝试单击登录按钮时，我发送了请求参数，并获取用户名和密码作为响应从给定的SOAP URL，但当我尝试获得一个respose xml pull解析器异常将occer我在这里犯了错误我附加了我的代码将任何人帮我从这个异常。

答案 0 :(得分：1)
当你的文件从请求中获得损坏时，你会得到“XML pull parser exception”，可能是错误的封闭标签或类似“HTTP error 503”的结果，当服务器不可用时会出现这种异常。
我建议您在SOAPObject调用
中为不同类型的异常提供额外的catch关闭P.S：提供你得到的回应
