• this is my first class UserService this class will call the

  package com.routingware.services;    
  import android.util.Log;
  
  import com.routingware.database.models.User;
  import org.ksoap2.SoapEnvelope;
  import org.ksoap2.serialization.PropertyInfo;
  import org.ksoap2.serialization.SoapObject;
  import org.ksoap2.serialization.SoapSerializationEnvelope;
  import org.ksoap2.transport.HttpTransportSE;
  
  public  String NAMESPACE = "http://tempuri.org/";
  public  String METHOD    = "";
  public  String ACTION    = "";
  public  String URL       = "http://192.168.173.1/projectnetwork/";
  
  public class UserService extends CommonClass {
  
      public UserService (String MethodName, String PageName) {
          METHOD = MethodName;
          ACTION = NAMESPACE + MethodName;
          URL    = URL + PageName;
      }
  
      public User CheckLogin (String Username, String Password) {
  
          User user = null;
  
          SoapObject Request = new SoapObject(NAMESPACE, METHOD);
  
          // Send Username as parameter
          PropertyInfo Pi = new PropertyInfo();
          Pi.setName("Username");
          Pi.setValue(Username);
          Pi.setType(String.class);
          Request.addProperty(Pi);
  
          // Send Password as parameter
          Pi = new PropertyInfo();
          Pi.setName("Password");
          Pi.setValue(Password);
          Pi.setType(String.class);
          Request.addProperty(Pi);
  
          SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
                  SoapEnvelope.VER11);
          envelope.dotNet = true;
          envelope.setOutputSoapObject(Request);
          envelope.implicitTypes = true;
  
          envelope.addMapping(NAMESPACE, "User",new User().getClass());
          HttpTransportSE httpTransport = new HttpTransportSE(URL);
          httpTransport.debug = true;
  
          try
          {
              Log.e("call","1");
              httpTransport.call(ACTION, envelope);
              SoapObject Response =  (SoapObject)envelope.getResponse();
  
              user = new User();
              user.setUserID(Integer.parseInt(Response.getProperty(0).toString()));
              user.setUserName(Response.getProperty(1).toString());
              user.setUserPasswrd(Response.getProperty(2).toString());
              user.setBranchID(Integer.parseInt(Response.getProperty(3).toString()));
              user.setCompanyID(Integer.parseInt(Response.getProperty(4).toString()));
              user.setUserState(Boolean.parseBoolean(Response.getProperty(5).toString()));
          }
          catch (Exception ex)
          {
              Log.e("call",ex.toString());
              return null;
          }
          finally
          {
              return user;
          }
      }
  }
  

• call method from AsyncTaskclass

  @Override
  protected User doInBackground(Void... params)
  {
      try
      {
          return new UserService("CheckFirstTimeLogin", "UserApi.asmx")
                  .CheckLogin(mUsername, mPassword);
      }
      catch (Exception e)
      {
          return null;
      }
  }
  
  @Override
  protected void onPreExecute()
  {
      super.onPreExecute();
      alertDialog = new AlertDialog.Builder(LoginActivity.this).create();
  }
  
  @Override
  protected void onPostExecute(User user)
  {
      if (user == null)
      {
          onCancelled();
          alertDialog.setTitle(R.string.login_connecnt_title);
          alertDialog.setMessage("خطأ اثناء عملية الإتصال");
          alertDialog.show();
      }
  }
