我在访问用 PHP 制作的 Web 服务时遇到问题。我尝试了很多代码，但不知道我是否有一个愚蠢的错误让我无法工作。
我认为 Web 服务很好，因为如果我从 PHP 中的页面进行调用，但如果我通过 Android 访问不起作用，那么我在 ANDROID 中进行的调用也是如此。
错误发生在：transporte.call(SOAP_ACTION,envelope,null);
错误是：org.xmlpull.v1.XmlPullParserException: expected: START_TAG {http://www.w3.org/2003/05/soap-envelope}Envelope (position:START_TAG <definitions name='SMB_GestionBoda' targetNamespace='http://localhost/webservice/SMB_GestionBoda.wdsl'>@8:43 in java.io.InputStreamReader@405d9f50)
谢谢。
