Question

1. this code is not giving me any errors or warning but is not working properly ,I did not know where is the problem,Please help me.

   package com.example.webtest;
   
   import org.ksoap2.SoapEnvelope;
   import android.util.Log;
   import org.ksoap2.serialization.SoapObject;
   import org.ksoap2.serialization.SoapPrimitive;
   import org.ksoap2.serialization.SoapSerializationEnvelope;
   import org.ksoap2.transport.HttpTransportSE;
   
   import android.os.Bundle;
   import android.app.Activity;
   import android.view.Menu;
   import android.view.View;
   import android.widget.Button;
   import android.widget.EditText;
   import android.widget.TextView;
   
   public class MainActivity extends Activity {
   
   String UserFahrenheit;
   
   
   @Override
   protected void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);
   setContentView(R.layout.activity_main);
   
   Button b=(Button) findViewById(R.id.button);
   final EditText Med=(EditText) findViewById(R.id.MedServTextView);
   final TextView Test=(TextView) findViewById(R.id.TestTextView);
   
   b.setOnClickListener(new View.OnClickListener() {
   
       @Override
       public void onClick(View v) {
           //try{
               UserFahrenheit=Med.getText().toString();
   
               //String mobile=getData(UserMRN.trim());
                String NAMESPACE = "http://tempuri.org/";
                   String METHOD_NAME = "FahrenheitToCelsius";
                   String SOAP_ACTION = "http://tempuri.org/FahrenheitToCelsius";
                   String URL = "http://www.w3schools.com/webservices/tempconvert.asmx?WSDL";
   
                   SoapObject Request = new SoapObject(NAMESPACE, METHOD_NAME);
   
                   Request.addProperty("Fahrenheit",UserFahrenheit.trim());
   
                   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();
                   String Celsius;
                   Celsius= String.valueOf(response.toString());
                  Test.setText(Celsius);
   
       }catch(Exception e){
           e.getMessage();
       }
   
   
   
       //  }catch(Exception e){
       //      e.getMessage();
       //  }
   
   
       }
   });
   
       }
   
   
   
   @Override
   public boolean onCreateOptionsMenu(Menu menu) {
   // Inflate the menu; this adds items to the action bar if it is present.
   getMenuInflater().inflate(R.menu.main, menu);
   return true;
   }
   
   }
   

Solution

Why are you using a SoapPrimitive? First of all, check if your response is an Error. Otherwise, get de responsebody from the response object by calling response.bodyIn:

SoapObject response = null;
if (envelope.bodyIn instanceof SoapObject) { // SoapObject = SUCCESS
    response = (SoapObject) envelope.bodyIn;
} else if (envelope.bodyIn instanceof SoapFault) { // SoapFault =
                                                    // FAILURE
    SoapFault soapFault = (SoapFault) envelope.bodyIn;
    throw new Exception(soapFault.getMessage());
}

Then, you can get properties from your response by calling response.getProperty("responsecode") for example.

Also, put the debug value of your HttpTransportSE on true while debugging:

transportSE.debug = true;

I am using SoapPrimitive becouse I return primitive value(String) from web services ,I also using SoabObject but it giving me NullPointerException in this statment SoapObject pii = (SoapObject)soap.getProperty(0).toString(); I did not know how to solve this problem so I swap this with SoapPrimitive

Don't directly parse your response to a string. You need to get the body of your response with the method bodyIn of your envelope, instead of calling getResponse() from the envelope. What is the value bodyIn returns?

I am using bodyIn but is not giving me any result
