Response from SOAP webservice always returns null Android studio

Im trying to get some response from several SOAP webservices at last i tried to run a code that is a well very known example on the internet. But i realized that even this doesnt run on my project. I hardly tried to understand what the error could be but i dont know why its not working with soap.
I would really appriacate your help.
Downloaded new version of KSOAP2 and also permission for internet is given.
public class WEBSERVİCE extends AppCompatActivity {
Button btn;
EditText et;
TextView txv;
String celcius="21";
String fahren;
private String NAMESPACE = "https://www.w3schools.com/xml/";
private String METHOD_NAME = "CelsiusToFahrenheit";
private String SOAP_ACTİON = "https://www.w3schools.com/xml/CelsiusToFahrenheit";
private String URL = "https://www.w3schools.com/xml/tempconvert.asmx?op=CelsiusToFahrenheit?WSDL";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btn = findViewById(R.id.button);
txv = findViewById(R.id.textView);
et = findViewById(R.id.editText1);
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
AsyncCallWS task = new AsyncCallWS();
task.execute();
}
});
}
private class AsyncCallWS extends AsyncTask<String, Void, String> {
#Override
protected void onPreExecute() {
txv.setText("calculating");
super.onPreExecute();
}
#Override
protected void onProgressUpdate(Void... values) {
super.onProgressUpdate(values);
}
#Override
protected String doInBackground(String... objects) {
return getBolum(celcius);
}
#Override
protected void onPostExecute(String o) {
txv.setText(fahren + "F");
super.onPostExecute(o);
}
}
public String getBolum(String celsius) {
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
PropertyInfo pi = new PropertyInfo();
pi.setName("Celcius");
pi.setValue(celsius);
pi.setType(double.class);
request.addProperty(pi);
SoapSerializationEnvelope envelope = new
SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet = true;
envelope.setOutputSoapObject(request);
HttpTransportSE androidHTTPTransport = new HttpTransportSE(URL);
try {
androidHTTPTransport.call(SOAP_ACTİON, envelope);
SoapPrimitive response = (SoapPrimitive) envelope.getResponse();
fahren = response.toString();
} catch (IOException e) {
e.printStackTrace();
} catch (XmlPullParserException e) {
e.printStackTrace();
}
return fahren;
}
}
No Error Messages but the value it turns back is always "null"
EDIT:posted changed code again

There isn't anything wrong with SOAP Api. The problem is your AsyncTask class. Read the documentation for AsyncTask first. Please do proper research before you use any code from internet. Always read about the components that are used snippets on internet otherwise you are going to have hard time figuring out problems.
Your AsyncTask class is declared as:
private class AsyncCallWS extends AsyncTask<String,Void,Void>
Change it to
private class AsyncCallWS extends AsyncTask<String,Void,String>
Third generic parameter in your Void which is supposed to be result type. So in your case your async task won't return any data once it is finished.
//CHANGE TYPE TO STRING
public String getBolum(String celsius) {
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
PropertyInfo pi=new PropertyInfo();
pi.setName("Celcius");
pi.setValue(celsius);
pi.setType(double.class);
request.addProperty(pi);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet = true;
envelope.setOutputSoapObject(request);
HttpTransportSE androidHTTPTransport = new HttpTransportSE(URL);
try {
androidHTTPTransport.call(SOAP_ACTİON, envelope);
SoapPrimitive response= (SoapPrimitive) envelope.getResponse();
//RETURN RESULT
return response.toString();
} catch (IOException e) {
e.printStackTrace();
} catch (XmlPullParserException e) {
e.printStackTrace();
}
//I forgot this line previously:
return "";
}}
In your async task, you need to change return type of doInBackground and paramter of onPostExecute to String:
#Override
protected String doInBackground(String... objects) {
return getBolum(celcius); //RETURN RESULT
}
#Override
protected void onPostExecute(String result) {
txv.setText(result+"F");
fahren = result;
super.onPostExecute(result);
}
It should work now.

Image loading using picasso library from url

initially, I am fetching image URL from server to a string then using Picasso library I am trying to load the image
I am able to get image URL from the server like thislogcat
but image not loaded in the image view. when tried placing direct URL it works.
public class MainActivity extends AppCompatActivity {
ImageView im;
Button bm;
String str ;
private static String NAMESPACE = "http://telview360/";
private static String URL = "http://54.179.134.139/viView360Service/WebService.asmx?WSDL";
private static String SOAP_ACTION = "http://telview360/ImageDetails";
private static String METHOD_NAME = "ImageDetails";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.load_image);
final Thread networkThread = new Thread() {
#Override
public void run() {
try {
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.setOutputSoapObject(request);
HttpTransportSE ht = new HttpTransportSE(URL);
ht.call(SOAP_ACTION, envelope);
final SoapPrimitive response = (SoapPrimitive) envelope.getResponse();
str = response.toString();
Log.d("Webservice", " response " + str);
} catch (Exception e) {
e.printStackTrace();
}
}
};
networkThread.start();
bm = (Button) findViewById(R.id.btn_load_image);
bm.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
im = (ImageView) findViewById(R.id.image);
Picasso.with(getApplicationContext()).load(str).into(im);
}
});
}
}

add this to your code
final Thread networkThread = new Thread() {
#Override
public void run() {
try {
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.setOutputSoapObject(request);
HttpTransportSE ht = new HttpTransportSE(URL);
ht.call(SOAP_ACTION, envelope);
final SoapPrimitive response = (SoapPrimitive) envelope.getResponse();
str = response.toString();
Log.d("Webservice", " response " + str);
} catch (Exception e) {
e.printStackTrace();
}
}
};
networkThread.start();
try {
Thread.currentThread().sleep(100);
} catch (InterruptedException e) {
e.printStackTrace();
}
it will work

getting error on setAdapter in AsyncTAsk?

I added the Row_Cursor_Adapter globally and made changes after adding onPostExecute() method in the Service_ivr AsyncTask.This is the updated code.
class Service_ivr extends AsyncTask<String, Void, String>
{
#Override
protected String doInBackground(String... param)
{
SoapObject request = new SoapObject(NAMESPACE ,METHOD_NAME);
request.addProperty("user_id",param[0]);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.bodyOut=request;
envelope.dotNet =true;
envelope.setOutputSoapObject(request);
try
{
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
androidHttpTransport.call(SOAP_ACTION, envelope);
SoapObject obj2 = (SoapObject)envelope.getResponse();
int count = obj2.getPropertyCount();
index = count/7;
final lead_content_IVR [] total_ivr_data = new lead_content_IVR[index];
for(int i=0; i<index ;i++)
{
String call_duration;
String lead_id = obj2.getPropertyAsString(i*7+0);
String lead_call_from = obj2.getPropertyAsString(i*7+1);
String lead_call_to = obj2.getPropertyAsString(i*7+2);
String lead_date=obj2.getPropertyAsString(i*7+3);
String lead_audio=obj2.getPropertyAsString(i*7+4);
String assign_id = obj2.getPropertyAsString(i*7+5);
String time = obj2.getPropertyAsString(i*7+6);
if(lead_call_from.equals("Welcome Sound") || lead_call_from.equals("Call Missed") || lead_call_from.equals("User Disconnected") || lead_call_from.equals("Customer Missed"))
{
call_duration= "5 sec";
}
else
{
call_duration = time.toString().concat(" sec");
}
total_ivr_data[i] = new lead_content_IVR(lead_id,lead_call_from,lead_call_to,lead_date,lead_audio,assign_id,call_duration);
}
adapter = new RowCursorAdapter_IVR(Activity_IVR_Lead.this, R.layout.listview_layout_ivr,total_ivr_data);
}catch(Exception e)
{
e.printStackTrace();
}
return null;
}
#Override
protected void onPostExecute(String s) {
super.onPostExecute(s);
listView.setAdapter(adapter);
}
}
As u suggest i update the code but error is same all the time.

Change your method like so
class service_ivr extends AsyncTask<String, Void, String>
{
#Override
protected lead_content_IVR[] doInBackground(String... param)
{
SoapObject request = new SoapObject(NAMESPACE ,METHOD_NAME);
request.addProperty("user_id",param[0]);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.bodyOut=request;
envelope.dotNet =true;
envelope.setOutputSoapObject(request);
lead_content_IVR [] total_ivr_data = null;
try
{
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
androidHttpTransport.call(SOAP_ACTION, envelope);
SoapObject obj2 = (SoapObject)envelope.getResponse();
int count = obj2.getPropertyCount();
index = count/7;
total_ivr_data = new lead_content_IVR[index];
for(int i=0; i<index ;i++)
{
String call_duration;
String lead_id = obj2.getPropertyAsString(i*7+0);
String lead_call_from = obj2.getPropertyAsString(i*7+1);
String lead_call_to = obj2.getPropertyAsString(i*7+2);
String lead_date=obj2.getPropertyAsString(i*7+3);
String lead_audio=obj2.getPropertyAsString(i*7+4);
String assign_id = obj2.getPropertyAsString(i*7+5);
String time = obj2.getPropertyAsString(i*7+6);
if(lead_call_from.equals("Welcome Sound") || lead_call_from.equals("Call Missed") || lead_call_from.equals("User Disconnected") || lead_call_from.equals("Customer Missed"))
{
call_duration= "5 sec";
}
else
{
call_duration = time.toString().concat(" sec");
}
total_ivr_data[i] = new lead_content_IVR(lead_id,lead_call_from,lead_call_to,lead_date,lead_audio,assign_id,call_duration);
}
}catch(Exception e)
{
e.printStackTrace();
}
return total_ivr_data;
}
public void onPostExecute(lead_content_IVR [] total_ivr_data ) {
RowCursorAdapter_IVR adapter = new RowCursorAdapter_IVR(Activity_IVR_Lead.this, R.layout.listview_layout_ivr,total_ivr_data);
listView.setAdapter(adapter);
}
}

not sure were iam doing wrong.Any help is appreciated.

You should do network realted operation on a thread. You can use a thread or AsyncTask.
Move your loginAction() inside a thread or inside doInbackground of AsyncTask.
Remember not to update ui from the back ground thread.
new TheTask().execute();
AsyncTask
public class TheTask extends AsyncTask <Void,Void,Void>
{
#Override
protected void onPreExecute() {
super.onPreExecute();
// display a dialog
}
#Override
protected Void doInBackground(Void... params) {
// your login authentcation
// remove updation of textview.
// do not update ui here
return null;
}
#Override
protected void onPostExecute(Void result) {
super.onPostExecute(result);
// dismiss the dialog
// update textview
}
}

Android Soap Web service Error behind Proxy Server

I have written a program for communicating with a web service and get response value. But when i debug the programme i end with requestDump=null at the line androidHttpTransport.call(SOAP_ACTION, envelope); Can some one tell me the reason for the error and what can i do for this
public class WebService extends Activity {
private final String NAMESPACE = "http://tempuri.org/";
private final String URL = "http://www.w3schools.com/webservices/tempconvert.asmx";
private final String SOAP_ACTION = "http://tempuri.org/CelsiusToFahrenheit";
private final String METHOD_NAME = "CelsiusToFahrenheit";
String celsius;
Button b;
TextView tv;
EditText et;
String res,resultval;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_web_service);
et=(EditText)findViewById(R.id.editText1);
tv=(TextView)findViewById(R.id.Result);
b=(Button)findViewById(R.id.button1);
b.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
//String result=getFarenheit(et.getText().toString());
//tv.setText(result+"°F");
new service().execute();
}
});
}

Just replace your service AsyncTask with this new one and see result:
code:
private class service extends AsyncTask<Void, Void, String> {
#Override
protected String doInBackground(Void... arg0) {
System.out.println("In DoIn Background");
// Initialize soap request + add parameters
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
// Use this to add parameters
request.addProperty("Celsius", txtCel.getText().toString());
// Declare the version of the SOAP request
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
SoapEnvelope.VER11);
envelope.setOutputSoapObject(request);
envelope.dotNet = true;
try {
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
// this is the actual part that will call the webservice
androidHttpTransport.call(SOAP_ACTION, envelope);
// Get the SoapResult from the envelope body.
SoapObject result = (SoapObject) envelope.bodyIn;
if (result != null) {
// Get the first property and change the label text
// txtFar.setText(result.getProperty(0).toString());
res = result.getProperty(0).toString();
} else {
Toast.makeText(getApplicationContext(), "No Response",
Toast.LENGTH_LONG).show();
}
} catch (Exception e) {
e.printStackTrace();
}
return res;
}
protected void onPostExecute(String h) {
String result = h;
tv.setText(result + "°F");
}
}
