Android Hintergrund Service ksoap Fehler

Question

Ich entwickle eine Android-Anwendung mit Hintergrund-Service, die eine Methode eines Web-Service auf alle 5 Minuten verbraucht. Ich verwende ksoap 2.4 und asp.net Webservice. Der Android-Hintergrunddienst läuft alle 5 Minuten, aber

androidHttpTransport.call(SOAP_ACTION+webMethName, envelope); 

gibt null zurück. hier ist mein Android Service-Code.

package com.example.rashid.challandb; 

import android.app.Service; 
import android.content.Context; 
import android.content.Intent; 
import android.os.IBinder; 
import org.ksoap2.SoapEnvelope; 
import org.ksoap2.serialization.MarshalBase64; 
import org.ksoap2.serialization.PropertyInfo; 
import org.ksoap2.serialization.SoapObject; 
import org.ksoap2.serialization.SoapSerializationEnvelope; 
import org.ksoap2.transport.HttpTransportSE; 
public class TestService extends Service { 
private static String NAMESPACE = "http://tempuri.org/"; 
private static String URL = "http://192.168.50.107:80/AndroidService/Service1.asmx"; 
private static String SOAP_ACTION = "http://tempuri.org/"; 
Context context; 
boolean isrunning; 
public TestService() { 
} 
@Override 
public void onCreate() 
{ 
    this.context=this; 
    this.isrunning=false; 
} 
@Override 
public IBinder onBind(Intent intent) { 
    return null; 
} 

@Override 
public int onStartCommand(Intent intent,int flags,int startid) { 
    if (!this.isrunning) { 
     this.isrunning = true; 
     synchronized (this) { 
      try { 
       String resTxt = "default"; 
       String webMethName="MyMethod"; 
       SoapObject request = new SoapObject(NAMESPACE, webMethName); 

       PropertyInfo first = new PropertyInfo(); 
       first.setName("Para"); 
       first.setValue("Hullow"); 
       first.setType(String.class); 
       request.addProperty(first); 

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

       HttpTransportSE androidHttpTransport = new HttpTransportSE(URL); 

       try { 

        androidHttpTransport.call(SOAP_ACTION+webMethName, envelope); 
        Object response = null; 
        response = (Object) envelope.getResponse(); 
        resTxt =response.toString(); 

       } catch (Exception e) { 
        e.printStackTrace(); 
        System.out.println( e.getMessage()+" Phone"); 
       } 

       System.out.println( resTxt); 

      } catch (Exception ex) { 
       System.out.println("Error:" + ex.getMessage()); 
      } 
      this.isrunning = false; 
      stopSelf(); 
     } 
    } 
    return START_STICKY; 
} 
@Override 
public void onDestroy() 
{ 
    this.isrunning=false; 
} 
}

Answer 1

Try

androidHttpTransport.call(SOAP_ACTION+webMethName, envelope); 

mit diesem

androidHttpTransport.call("", envelope); 

noch nicht gelöst zu ersetzen ist, überprüfen Sie bitte die Ausnahme Rückkehr in diese Zeile

System.out.println("Error:" + ex.getMessage()); 

EDIT

SoapObject request = new SoapObject(NAMESPACE, webMethName); 
request.addProperty("Para", "Hullow"); 

dem Teil Property entfernen
