Android soap web服务超时已过期

Question

使用以下代码调用soap webservice：

    SoapObject request = new SoapObject(Constants.NAMESPACE, METHOD_NAME);

    AppLog.logString(TAG+"Property info");
    PropertyInfo proInfo = new PropertyInfo();
    proInfo.setName("strInputData");
    proInfo.setValue(jsonValue);
    proInfo.setType(String.class);
    request.addProperty(proInfo);

    AppLog.logString(TAG+"envelope");
    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
    envelope.setOutputSoapObject(request);
    envelope.dotNet = true;

    AppLog.logString(TAG+"HttpTransportSE");
    HttpTransportSE androidHttpTransport = new HttpTransportSE(Constants.URL, 30000);
    androidHttpTransport.debug = true;

    try {
        AppLog.logString(TAG+"call");
        androidHttpTransport.call(Constants.NAMESPACE+METHOD_NAME, envelope);
        AppLog.logString(TAG+"call1");
        SoapPrimitive response = (SoapPrimitive) envelope.getResponse();
        AppLog.logString(TAG+"Responce: "+response.toString());
        result=response.toString();
    } catch (Exception e){
        e.printStackTrace();
    }
