默认情况下，Android SDK中包含defaulthttpclient。这将使您连接到WSDL。

HttpClient httpClient = new DefaultHttpClient();
HttpContext localContext = new BasicHttpContext();
HttpGet httpGet = new HttpGet("http://www.example.com/" + URL);
HttpResponse response = httpClient.execute(httpGet, localContext);

我相信您可以用Axis创建一个小型SOAP客户机。轴安装说明。

要从移动设备(尤其是Android手机)调用web服务，我使用了一种非常简单的方法。我没有使用任何web服务客户端API试图调用web服务。我打电话的方法如下。

Create a simple HTTP connection by using the Java standard API HttpURLConnection. Form a SOAP request. (You can make help of SOAPUI to make a SOAP request.) Set doOutPut flag as true. Set HTTP header values like content-length, Content type, and User-agent. Do not forget to set Content-length value as it is a mandatory. Write entire the SOAP request to the output stream. Call the method to make a connection and receive the response (In my case I used getResonseCode). If your received response code as It means you are succeeded to call web service. Now take an input stream on the same HTTP connection and receive the string object. This string object is a SOAP response. If the response code is other than 200 then take a ErrorInput stream on same HTTPobject and receive the error if any. Parse the received response using SAXParser (in my case) or DOMParaser or any other parsing mechanism.

我已经在Android手机上实现了这个过程，并且它正在成功运行。我能够解析响应，即使它超过700 KB。

大约一年前，我读了这篇文章，试图弄清楚如何在Android上执行SOAP调用——使用HttpClient构建我自己的SOAP库的建议导致我为Android构建了自己的SOAP库:

IceSoap

基本上，它允许您构建通过简单的Java API发送的信封，然后自动将它们解析为通过XPath定义的对象……例如:

<Dictionary>
    <Id></Id>
    <Name></Name>
</Dictionary>

就变成:

@XMLObject("//Dictionary")
public class Dictionary {
    @XMLField("Id")
    private String id;

    @XMLField("Name")
    private String name;
}

我在我自己的项目中使用它，但我认为它可能会帮助其他人，所以我花了一些时间把它分离出来并记录下来。我真的很喜欢它，如果你的一些可怜的灵魂在谷歌“SOAP Android”时偶然发现这条线索，可以尝试一下，并得到一些好处。

我建议你查看一个非常有用的工具，它对我帮助很大。的人 负责那个项目的人也很有帮助。 www.wsdl2code.com/

如果你有关于在android中调用Web服务的问题 您可以使用下面的代码来调用web服务并获得响应。确保您的web服务以数据表格式返回响应..如果您使用SQL Server数据库中的数据，此代码将帮助您。如果你使用MYSQL，你需要改变一件事，只需替换单词NewDataSet从句子obj2=(SoapObject) obj1.getProperty("NewDataSet");由DocumentElement

void callWebService(){ 

private static final String NAMESPACE = "http://tempuri.org/"; // for wsdl it may be package name i.e http://package_name
private static final String URL = "http://localhost/sample/services/MyService?wsdl";
// you can use IP address instead of localhost
private static final String METHOD_NAME = "Function_Name";
private static final String SOAP_ACTION = "urn:" + METHOD_NAME;

    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
    request.addProperty("parm_name", prm_value);// Parameter for Method
    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
    envelope.dotNet = true;// **If your Webservice in .net otherwise remove it**
    envelope.setOutputSoapObject(request);
    HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);

    try {
        androidHttpTransport.call(SOAP_ACTION, envelope);// call the eb service
                                                                                                         // Method
    } catch (Exception e) {
        e.printStackTrace();
    }

    // Next task is to get Response and format that response
    SoapObject obj, obj1, obj2, obj3;
    obj = (SoapObject) envelope.getResponse();
    obj1 = (SoapObject) obj.getProperty("diffgram");
    obj2 = (SoapObject) obj1.getProperty("NewDataSet");

    for (int i = 0; i < obj2.getPropertyCount(); i++) { 
// the method getPropertyCount() and  return the number of rows
            obj3 = (SoapObject) obj2.getProperty(i);
            obj3.getProperty(0).toString();// value of column 1
            obj3.getProperty(1).toString();// value of column 2
            // like that you will get value from each column
        }
    }
