Question

我从Android应用程序连接我的Web服务时遇到问题。也许我使用了错误的参数？

的活动：

public class MainActivity extends Activity {

final private String METHOD_NAME = "getMenuePlan";
final private String NAMESPACE = "http://webservice.kantine.de/";
final private String SOAP_ACTION = "\"" + NAMESPACE + METHOD_NAME + "\"";
final private String URL = "http://10.0.2.2:8080/Kantine/MenuePlan?wsdl";

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);

    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);

    envelope.setOutputSoapObject(request);

    HttpTransportSE httpTransport = new HttpTransportSE(URL);
    SoapObject result = null;


    try {

        httpTransport.call(SOAP_ACTION, envelope);
        result = (SoapObject) envelope.getResponse();

    } catch (SoapFault e) {

        Log.e("error", "", e);

    } catch (IOException e) {

        Log.e("error", "", e);

    } catch (XmlPullParserException e) {

        Log.e("error", "", e);

    }

    if (result != null) {
        Log.i("Result", result.toString());
    } else {
        Log.i("Result", "null");
    }
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.activity_main, menu);
    return true;
}

}

WSDL：

<wsdl:definitions name="KantineWSImplService" targetNamespace="http://webservice.kantine.de/"><wsdl:types><xs:schema elementFormDefault="unqualified" targetNamespace="http://webservice.kantine.de/" version="1.0"><xs:element name="getMenuePlan" type="tns:getMenuePlan"/><xs:element name="getMenuePlanResponse" type="tns:getMenuePlanResponse"/><xs:complexType name="getMenuePlan"> [...]

例外：
