我后我的工作code为消费WCF（WCF的结合已是basicHttpBinding的！）：

 私有静态最后弦乐NAMESPACE =htt​​p://tempuri.org/;
私有静态字符串URL =您的网址;

私有静态最后弦乐SOAP_ACTION_VALIDATION =IValidateUser_wcf /的ValidateUser;
私有静态最后弦乐VALIDATION_METHOD =的ValidateUser;

公共布尔validateUser_WCF（字符串用户名，字符串密码）{

    SoapSerializationEnvelope信封= NULL;
    SoapObject请求= NULL;
    HttpTransportSE httpTransportSE = NULL;

    尝试 {
        要求=新SoapObject（命名空间VALIDATION_METHOD）;
        request.addProperty（用户名，用户名）;
        request.addProperty（密码，密码）;

        信封=新SoapSerializationEnvelope（SoapEnvelope.VER11）;
        envelope.dotNet = TRUE;
        envelope.setOutputSoapObject（要求）;

            //////////////////////////////
            //这里你可以，如果你想添加一个Header元素
        元素[]头=新的元素[1];

        标题[0] =新元素（）的createElement（NAMESPACE_INFOCAD，A1）。
        头[0] .addChild（Node.TEXTHeaderTextContent）;

        envelope.headerOut =报头;
            //////////////////////////////

        httpTransportSE =新HttpTransportSE（URL + VALIDATION_URI，10 * 10000）; //第二个参数是超时
        httpTransportSE.debug = TRUE;
        httpTransportSE.setXmlVersionTag（＆所述;？xml的版本= \1.0 \编码= \utf-8的\＆GT;？）;
        httpTransportSE.call空间（namespace + SOAP_ACTION_VALIDATION，包）;

            //如果响应是一个简单的文本结果，你可以调用SoapPrimitive，如果不是，你必须调用SoapObject结果和浏览响应的树像一个XML文件
        SoapPrimitive结果=（SoapPrimitive）envelope.getResponse（）;

        //获取数据。
        串textResult = result.toString（）;
        Log.i（textResult，textResult）;

                    返回true;

    }赶上（例外五）{
        // TODO：处理异常
        e.printStackTrace（）;
    }最后{
                 //在这里你可以在日志中看到什么是你发送请求的，什么是收到响应
                Log.i（的getClass（）getSimpleName（），requestDump：+ httpTransportSE.requestDump。）;
                Log.i（的getClass（）getSimpleName（），responseDump：+ httpTransportSE.responseDump。）;
    }

    返回false;
}
 

希望我的code可以帮助你:)。它工作在100％

I have done a simple project to call wcf web service using ksoap2. But when it calls envelope.getResponse(); it gives error saying

Error: SoapFault - faultcode: 'a:InternalServiceFault' faultstring: 'The server was unable to process the request due to an internal error. For more information about the error, either turn on IncludeExceptionDetailInFaults (either from ServiceBehaviorAttribute or from the configuration behavior) on the server in order to send the exception information back to the client, or turn on tracing as per the Microsoft .NET Framework 3.0 SDK documentation and inspect the server trace logs.' faultactor: 'null' detail: null

<PhoneData>
<OTA>1234</OTA>
</PhoneData>

I post my working code for consuming a WCF (binding of WCF has to be basicHttpBinding!):

private static final String NAMESPACE = "http://tempuri.org/";
private static String URL="your url";

private static final String SOAP_ACTION_VALIDATION = "IValidateUser_wcf/ValidateUser";
private static final String VALIDATION_METHOD = "ValidateUser";

public boolean validateUser_WCF(String username, String password){

    SoapSerializationEnvelope envelope = null;
    SoapObject request = null;
    HttpTransportSE httpTransportSE = null;

    try {
        request = new SoapObject(NAMESPACE, VALIDATION_METHOD);
        request.addProperty("username", username);
        request.addProperty("password", password);

        envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
        envelope.dotNet = true; 
        envelope.setOutputSoapObject(request);

            //////////////////////////////                               
            // here you can add a HEADER element if you want
        Element[] header = new Element[1];  

        header[0] = new Element().createElement(NAMESPACE_INFOCAD, "a1");                
        header[0].addChild(Node.TEXT, "HeaderTextContent");

        envelope.headerOut = header;
            //////////////////////////////                               

        httpTransportSE = new HttpTransportSE(URL+VALIDATION_URI, 10*10000); // second parameter is timeout
        httpTransportSE.debug = true;
        httpTransportSE.setXmlVersionTag("<?xml version=\"1.0\" encoding=\"utf-8\"?>");
        httpTransportSE.call(NAMESPACE+SOAP_ACTION_VALIDATION, envelope);

            // if response is a simple text result, you can call SoapPrimitive, if not, you have to call SoapObject result and navigate in response's tree like an xml file
        SoapPrimitive result = (SoapPrimitive)envelope.getResponse();

        //To get the data.
        String textResult = result.toString();
        Log.i("textResult", textResult); 

                    return true;

    } catch (Exception e) {
        // TODO: handle exception
        e.printStackTrace();
    }finally{
                 // here you can see in LOG what is request you send and what is response received
                Log.i(getClass().getSimpleName(),"requestDump : "+httpTransportSE.requestDump);
                Log.i(getClass().getSimpleName(),"responseDump : "+httpTransportSE.responseDump);
    }

    return false;
}

Hope my code can help you :). It works at 100%
