Mam problem podczas wywoływania usługi internetowej. Mam usługę sieciową .NET na serwerze i używam KSOAP2 (pełna wersja ksoap2-j2se-2.1.2) w Androidzie. Podczas uruchamiania programu otrzymałem wyjątek czasu wykonywania, taki jak „org.ksoap2.serialization.SoapPrimitive”. Co powinienem zrobić?

Oto mój kod.

<code>package projects.ksoap2sample;

import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;

import android.app.*;
import android.os.*;
import android.widget.TextView;

public class ksoap2sample extends Activity {
    /** Called when the activity is first created. */
    private static final String SOAP_ACTION = "http://tempuri.org/HelloWorld";
    private static final String METHOD_NAME = "HelloWorld";
    private static final String NAMESPACE = "http://tempuri.org/";
    private static final String URL = "http://192.168.1.19/TestWeb/WebService.asmx";
    TextView tv;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        tv=(TextView)findViewById(R.id.text1);

        try {
            SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);

            //request.addProperty("prop1", "myprop");

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

            HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);

            androidHttpTransport.call(SOAP_ACTION, envelope);

            Object result = (Object)envelope.getResponse();

            String[] results = (String[])  result;
            tv.setText( ""+results[0]);
        }
        catch (Exception e) {
            tv.setText(e.getMessage());
        }
    }
}
