その私のソースコード、
private static final String URL = "http://footballpool.dataaccess.eu/data/info.wso";
private static final String NAME_SPACE = "http://footballpool.dataaccess.eu";
private static final String METHODE_NAME = "TopGoalScorers";
private static final String SOAP_ACTION = NAME_SPACE + "/" + METHODE_NAME;
SoapObject request = new SoapObject(NAME_SPACE, METHODE_NAME);
request.addProperty("iTopN", 10);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
SoapEnvelope.VER11);
envelope.setOutputSoapObject(request);
HttpTransportSE transporte = new HttpTransportSE(URL);
SoapObject soapObject = null;
try {
transporte.call("http://footballpool.dataaccess.eu/data/info.wso/TopGoalScorers", envelope);
soapObject = (SoapObject) envelope.getResponse();
} catch (Exception e) {
Log.e("Soap", e.getMessage());
}
そして、私はこのエラーを出します:
