//coding

In this coding have to get those details and show it in one text box.But it doesn't go to the service call method, and add internet permissions and ksoap library also

SoapObject request = new SoapObject(WSDL_TARGET_NAMESPACE,OPERATION_NAME);



        envelope=new SoapSerializationEnvelope(SoapEnvelope.VER11);
        envelope.dotNet=true;
        envelope.setOutputSoapObject(request);

        httpTransport = new HttpTransportSE(SOAP_ADDRESS);


        try {
                serviceCall();

        } catch (Exception exception) 
        {


            }
}


     public void serviceCall() {


          progress.setMessage("Redirecting credientials...");
     progress.show();

        // TODO Auto-generated method stub
        new AsyncTask<Void, Void, Void>() {
            @Override
        protected Void doInBackground(Void... params) {  \\doinbackground process
            try {

                httpTransport.call(SOAP_ACTION, envelope);
                response = envelope.getResponse();
            }
             catch (IOException e) {
                // TODO Auto-generated catch block
                timeoutexcep=true;
                e.printStackTrace();
            } catch (XmlPullParserException e) {
                // TODO Auto-generated catch block
                httpexcep=true;
                e.printStackTrace();
            }

            return null;
        }
            @Override

            protected void onPostExecute(Void result) { \\post execute 
                    String str = "",str1="";

                    if(timeoutexcep){
                        Toast.makeText(Signup.this, "Unable to connect to server, Please try again later",Toast.LENGTH_LONG).show();
                        }
                    else if(httpexcep){
                        Toast.makeText(Signup.this, "Check Your Internet Connection",Toast.LENGTH_LONG).show();
                        }
                    else if(generalexcep){
                        Toast.makeText(Signup.this, "Please try again later",Toast.LENGTH_LONG).show();
                        }

                    else {

                        }           
                timeoutexcep=false;httpexcep=false;generalexcep=false;  
                    ArrayList<String> a = new ArrayList<String>();
                    if (progress != null)
                        progress.dismiss();
                    if (response !=null)
                    {
                           uid.setText(str);
                               Log.e("", str);


                    }
                    else
                    {
                                                }
                }
            }.execute();
