comment Appeler ksoap service web à partir d'android?

J'ai une petite confusion, dans notre application mobile une ksoap service web appelé à partir d'ios comme ci-dessous : et l'obtention de données correctement. Ici, dans le service web suivante, vous pouvez voir à partir de code suivant, il y a quelques paramètres à passer au service web.

 -(void)callwebservice{
    NSString *soapMessage = [NSString stringWithFormat:
                             @"<s:Envelope xmlns:s=\"http://schemas.xmlsoap.org/soap/envelope/\"><s:Body><Calculate xmlns=\"http://tempuri.org/\"><inputRate>%@</inputRate><rateFrequency xmlns:a=\"http://schemas.datacontract.org/2004/07/FusionPeople.MobileContractor.DomainModel\" xmlns:i=\"http://www.w3.org/2001/XMLSchema-instance\"><a:RateFrequencyId>0</a:RateFrequencyId><a:RateFrequencyName>%@</a:RateFrequencyName></rateFrequency><nonTaxableExpense>%@</nonTaxableExpense><expenseFrequency xmlns:a=\"http://schemas.datacontract.org/2004/07/FusionPeople.MobileContractor.DomainModel\" xmlns:i=\"http://www.w3.org/2001/XMLSchema-instance\"><a:RateFrequencyId>0</a:RateFrequencyId><a:RateFrequencyName>%@</a:RateFrequencyName></expenseFrequency></Calculate></s:Body></s:Envelope>\n",txtinputrate.text,lblrate.text,txtexpenses.text,lblexpense.text
                             ];

    NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"%@MobileContractorCalculationService.svc",[MobileContractorAppDelegate getstrIpAddress] ]];
    NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url];
    NSString *msgLength = [NSString stringWithFormat:@"%d",[soapMessage length]];
    [theRequest addValue:@"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
    [theRequest addValue:@"http://tempuri.org/IMobileContractorCalculationService/Calculate" forHTTPHeaderField:@"SOAPAction"];
    [theRequest addValue: msgLength forHTTPHeaderField:@"Content-Length"];
    [theRequest setHTTPMethod:@"POST"];
    [theRequest setHTTPBody: [soapMessage dataUsingEncoding:NSUTF8StringEncoding]];
    NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
    if( theConnection ){
        webData = [NSMutableData data] ;
    }
}

Et de l'autre côté, à côté android, j'ai essayé beaucoup de méthodes pour appeler ce service web et de transmettre des données de service web .Mais à chaque fois que je reçois de côté de serveur de code d'erreur: 415, Svp quelqu'un peut m'aider et me dire comment faire pour passer cette organisation hiérarchique des données pour ce type de ksoap service web....

J'ai essayé le code suivant :

try {
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
request.addProperty("inputRate", 1000);
SoapObject rate = new SoapObject(SOAP_ACTION, "rateFrequency");
PropertyInfo info = new PropertyInfo();
info.setName("RateFrequencyId");
info.setValue(0);
rate.addProperty(info);
PropertyInfo info2 = new PropertyInfo();
info2.setName("RateFrequencyName");
info2.setValue("Hourly");
rate.addProperty(info2);
request.addProperty("rateFrequency", rate);
request.addProperty("nonTaxableExpense", 500);
SoapObject exp = new SoapObject(SOAP_ACTION, "expenseFrequency");
PropertyInfo info3 = new PropertyInfo();
info3.setName("RateFrequencyId");
info3.setValue(0);
exp.addProperty(info3);
PropertyInfo info4 = new PropertyInfo();
info4.setName("RateFrequencyName");
info4.setValue("Hourly");
exp.addProperty(info4);
request.addProperty("expenseFrequency", exp);
Log.v("", "=========== Request : " + request);
SoapSerializationEnvelope envelope = new
SoapSerializationEnvelope(
SoapEnvelope.VER11);
envelope.dotNet = true;
envelope.setOutputSoapObject(request);
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
try {
androidHttpTransport.call(SOAP_ACTION, envelope);
SoapPrimitive response = (SoapPrimitive) envelope.getResponse();
Log.v("myApp",
"========================== Res" + response.toString());
} catch (Exception e) {
e.printStackTrace();
}

Mais il se message d'erreur suivant :
