HttpTransportSE .call() method has no action

问题

I'm trying to make an Android App that gets the weather based off a zipcode you enter, and that also displays the time in EST and GMT format. I am using webservices (WSDLs) and have the code written to access it, the code is below:

public void sendMessage(View view)
{
    SOAP_ACTION = "http://ws.cdyne.com/WeatherWS/GetCityWeatherByZIP";
    NAMESPACE = "http://ws.cdyne.com/WeatherWS/";
    METHOD_NAME = "GetCityWeatherByZIP";
    URL = "http://wsf.cdyne.com/WeatherWS/Weather.asmx?wsdl";

    txtZIP = (EditText) findViewById(R.id.zipcode);
    temp = (TextView) findViewById(R.id.displayTemp);
    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);

    PropertyInfo property = new PropertyInfo();
    {
        property.name = "zipcode";
        property.setNamespace(NAMESPACE);
        property.type = PropertyInfo.STRING_CLASS;
        property.setValue(txtZIP.getText().toString());
    }

    request.addProperty(property);

    //request.addProperty("zipcode", txtZIP.getText().toString());

    Toast.makeText(getApplicationContext(), "btnZIP pressed", Toast.LENGTH_LONG).show();
    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER10);
    envelope.setOutputSoapObject(request);
    envelope.implicitTypes = true;
    envelope.dotNet = true;
    HttpTransportSE androidHTTP = new HttpTransportSE(URL, 600);

    try {
        Toast.makeText(getApplicationContext(), "In try statement", Toast.LENGTH_LONG).show();

        androidHTTP.call(SOAP_ACTION, envelope);

        // SoapPrimitive resp = (SoapPrimitive) envelope.getResponse();
        SoapObject result = (SoapObject) envelope.bodyIn;

        if(result != null)
        {
            Toast.makeText(getApplicationContext(), "In IF statement", Toast.LENGTH_LONG).show();
            //temp.append("in IF statement, result not null");
        } else {
            Toast.makeText(getApplicationContext(), "In ELSE statement", Toast.LENGTH_LONG).show();
            //temp.append("in IF statement, result IS null");
        }

    } catch (HttpResponseException e) {
        Toast.makeText(getApplicationContext(), "No Response", Toast.LENGTH_LONG).show();
        e.printStackTrace();
    } catch (XmlPullParserException e){
        Toast.makeText(getApplicationContext(), "XML Pull exe", Toast.LENGTH_LONG).show();
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } catch (Exception e) {
        e.printStackTrace();
    }
}

Now, my problem is that with the androidHTTP.call(SOAP_ACTION, envelope); method, nothing is happening. I have Toast methods to show what is being executed, and the furthest I get is into the try block, but never into the if statement.

I have tried looking around seeing what might be the cause and a solution, but I can't seem to find anything for this specific problem. I've extended the time-out for the server to 600 and even made the implicitType to true, but nothing is working. I know I am using SoapEnvelope.VER10 for this method, but I have two other methods where I used VER11 and VER12 and there's no change. If anyone might have an idea as to what might be going on, I'd really appreciate the help. Also, the AndroidManifest.xml has the necessary uses-permission line to access the internet.

!!!! WORKING CONFIRMED !!!

main

public class MainActivity extends Activity{

public static String rslt,thread;
SoapMiddleMan c;

EditText txtZIP;
TextView weather;

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_main);     

    txtZIP = (EditText)findViewById(R.id.zipCode);
    weather = (TextView)findViewById(R.id.weather);

  }

public void sendMessage(View view)
{
    try{
            // condition for keeping the main thread asleep
            thread = "START";

            // create a new webservice caller thread
            c = new SoapMiddleMan();

            // join the new thread, start it and then select what webservice you want to access
            c.join();c.setZip(txtZIP.getText().toString()); c.start();

            // keep this thread asleep while the service thread is running
            while(thread=="START")
            {   
                try
                    {
                        Thread.sleep(10);
                    }
                catch(Exception e)
                    {
                        rslt="Failed2";
                    }
            }
        }

    catch(Exception e)
    {
        e.printStackTrace();
    }

    weather.setText(rslt);
}
}

middleman

public class SoapMiddleMan extends Thread {

private String zip;
private SoapSenderClass cs;

public void run(){

    try{
         cs=new SoapSenderClass();
         String resp=cs.getWeather(zip);
         MainActivity.rslt=resp; //public string in calling activity
         System.out.println("reached 2 \n");
        }catch(Exception ex)

        {
            MainActivity.rslt=ex.toString();
        }


        MainActivity.thread = "done";
    }

public void setZip(String searchZip)
{
    zip = searchZip;
}

}

Caller

public class SoapSenderClass{

String SOAP_ACTION = "http://ws.cdyne.com/WeatherWS/GetCityWeatherByZIP";
String NAMESPACE = "http://ws.cdyne.com/WeatherWS/";
String METHOD_NAME = "GetCityWeatherByZIP";
String URL = "http://wsf.cdyne.com/WeatherWS/Weather.asmx?wsdl";


public String getWeather(String zipcode)
{
    try{
    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);

    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);

    envelope.dotNet = true;

    PropertyInfo property = new PropertyInfo();

    property.setName("ZIP");
    property.setType(String.class);
    property.setValue(zipcode);
    request.addProperty(property);

    envelope.setOutputSoapObject(request);

    HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);

    androidHttpTransport.call(SOAP_ACTION, envelope);

    SoapObject response = (SoapObject)envelope.getResponse();

    String resultValue = response.toString();

    return resultValue;

} 
catch (Exception e) {
    e.printStackTrace();
    return "Failed to get ID";
}

}
}

I have simplified your caller code and I changed the name of the addproperty to ZIP which is what it looks like the input is called in the WSDL. Removed the brackets for the property calls removed Namespace which isnt needed as far as I can tell.
