android app Failed to connect to WCF web service using soap

Hi I Couldn't to connect to wcf Web service soap C# I tried to connect with using soap to wcf in app android in android studio. I think the problem is from namespace ,url ,soap_action and method name.

my code :

public class MainActivity extends ActionBarActivity {
private final String NAMESPACE = "http://tempuri.org/";
private final String URL = "http://ift.tt/1yG0mya";
private final String SOAP_ACTION = "http://ift.tt/1yG0oGj";
private final String METHOD_NAME = "Search";
private String TAG = "PGGURU";
private static String celcius;
private static String fahren;
Button b;
TextView tv;
EditText et;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    //Celcius Edit Control
    et = (EditText) findViewById(R.id.editText1);
    //Fahrenheit Text control
    tv = (TextView) findViewById(R.id.tv_result);
    //Button to trigger web service invocation
    b = (Button) findViewById(R.id.button1);
    //Button Click Listener
    b.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            //Check if Celcius text control is not empty
            if (et.getText().length() != 0 && et.getText().toString() != "") {
                //Get the text control value
                celcius = et.getText().toString();
                //Create instance for AsyncCallWS
                AsyncCallWS task = new AsyncCallWS();
                //Call execute
                task.execute();
                //If text control is empty
            } else {
                tv.setText("Please enter Celcius");
            }
        }
    });
}

private class AsyncCallWS extends AsyncTask<String, Void, Void> {
    @Override
    protected Void doInBackground(String... params) {
        Log.i(TAG, "doInBackground");
        getFahrenheit(celcius);
        return null;
    }

    @Override
    protected void onPostExecute(Void result) {
        Log.i(TAG, "onPostExecute");
        tv.setText(fahren + "° F");
    }

    @Override
    protected void onPreExecute() {
        Log.i(TAG, "onPreExecute");
        tv.setText("Calculating...");
    }

    @Override
    protected void onProgressUpdate(Void... values) {
        Log.i(TAG, "onProgressUpdate");
    }

}
public void getFahrenheit(String celsius) {
    //Create request
    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
    //Property which holds input parameters
    PropertyInfo celsiusPI = new PropertyInfo();
    //Set Name
    celsiusPI.setName("searchValue");
    //Set Value
    celsiusPI.setValue("اصفهان");
    //Set dataType
    celsiusPI.setType(String.class);
    request.addProperty(celsiusPI);
    PropertyInfo celsiusPI2 = new PropertyInfo();

    //Set Name
    celsiusPI2.setName("languageId");
    //Set Value
    celsiusPI2.setValue(1);
    //Set dataType
    celsiusPI2.setType(int.class);
    //Add the property to request object
    request.addProperty(celsiusPI2);
    //Create envelope
    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
            SoapEnvelope.VER11);
    envelope.dotNet = true;
    //Set output SOAP object
    envelope.setOutputSoapObject(request);
    //Create HTTP call object
    HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);

    try {
        //Invole web service
        androidHttpTransport.call(SOAP_ACTION, envelope);
        //Get the response
        SoapPrimitive response = (SoapPrimitive) envelope.getResponse();
        //Assign it to fahren static variable
        fahren =response.toString();

    } catch (Exception e) {
        e.printStackTrace();
    }
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu_main, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();

    //noinspection SimplifiableIfStatement
    if (id == R.id.action_settings) {
        return true;
    }

    return super.onOptionsItemSelected(item);
}
}
