Hi,

I developed a code to post username and password to a web server and get login, after that will read different page with same domain.
i have enabled CookieManager but i dont know how to change the url.

package com.example.sadeq.webloginprototypev4o;

import android.os.AsyncTask;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.Toast;

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.io.OutputStreamWriter;
import java.net.CookieHandler;
import java.net.CookieManager;
import java.net.URL;
import java.net.URLEncoder;
import java.util.HashMap;
import java.util.Scanner;

import javax.net.ssl.HttpsURLConnection;

public class login extends AppCompatActivity {


    private EditText usrname;
    private EditText password;
    private TextView message;
    private Button login;
    String sUsrname, sPassword;
    String text = "";
    int code;
    int lines = 0;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_login);

        usrname = (EditText) findViewById(R.id.editText);
        password = (EditText) findViewById(R.id.editText2);
        message = (TextView) findViewById(R.id.textView4);
        login = (Button) findViewById(R.id.button);

        login.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                sUsrname = usrname.getText().toString();
                sPassword = password.getText().toString();
                System.out.println("userName: " + sUsrname + " Password: " + sPassword);

                new JSONTask().execute("https://lms.arabou.edu.kw/bahrain_hq/login/index.php");
                //message.setText(myName(text));
            }
        });

    }
    private String myName(String t){

        String Name = "";
        Scanner sc = new Scanner(t);
        String temp = "https://lms.arabou.edu.kw/bahrain_hq/user/profile.php?id=";
        while(sc.hasNext()){
            if(sc.next().equals("content=\"moodle,")) {
                Name = sc.next() + sc.next();
                break;
            }
        }
        return Name;

    }

    public class JSONTask extends AsyncTask<String, String, String> {
        @Override
        protected String doInBackground(String... params) {
            HttpsURLConnection con = null;


            try{
                String data  = URLEncoder.encode("username", "UTF-8") + "=" + URLEncoder.encode(sUsrname, "UTF-8");
                data += "&" + URLEncoder.encode("password", "UTF-8") + "=" + URLEncoder.encode(sPassword, "UTF-8");
                CookieManager cookieManager = new CookieManager();
                CookieHandler.setDefault(cookieManager);
                URL url = new URL(params[0]);
                con = (HttpsURLConnection) url.openConnection();

                con.setDoOutput(true);


                OutputStreamWriter bw = new OutputStreamWriter(con.getOutputStream());



                bw.write(data);
                bw.flush();

                InputStream stream = con.getInputStream();
                BufferedReader reader = new BufferedReader(new InputStreamReader(stream));

                StringBuilder sb = new StringBuilder();
                String line = "";
                while((line = reader.readLine())!= null){
                    sb.append(line+"\n");
                    lines++;
                }
                return sb.toString();

            }catch (Exception e){
                return new String("Exception: " + e.getMessage());
            }
        }

        @Override
        protected void onPostExecute(String result) {
            super.onPostExecute(result);
            System.out.println(result);
            text = result;
            Toast.makeText(getApplicationContext(), "Number of lines: " + lines, Toast.LENGTH_LONG).show();
        }


    }//END JCLASS

}
