XMPP and Android Part-2

Question

This question is continuation of my previous question though i have managed to remove the NetworkOnMainThreadError, now i have new errors to fight with,

Previous question can be found here: XMPP and ANDROID

This time i guess the probelm is with my host name, or may be service name, i am trying to connect to openFire server.

By the way do i need to add public class SettingsDialog extends Dialog into Menifest file

My code for connection:

/**
 * Gather the xmpp settings and create an XMPPConnection
 */
public class SettingsDialog extends Dialog implements android.view.View.OnClickListener {
    private XMPPClient xmppClient;

    public SettingsDialog(XMPPClient xmppClient) {
        super(xmppClient);
        this.xmppClient = xmppClient;
    }

    protected void onStart() {
        super.onStart();
        setContentView(R.layout.settings);
        getWindow().setFlags(4, 4);
        setTitle("XMPP Settings");
        Button ok = (Button) findViewById(R.id.ok);
        ok.setOnClickListener(this);
    }


        public void onClick(View v) {

            new NetworkOperation().execute();
            dismiss();
        }

Async Task

public class NetworkOperation extends AsyncTask<String, Void, String> {

    private XMPPClient xmppClient;
    @Override
    protected String doInBackground(String... urls) {

        String host = "web.vlivetech.com"; //getText(R.id.host);
        String port = "5222";  //getText(R.id.port);
        String service = "web.vlivetech.com"; //getText(R.id.service);
        String username = "khubaib@web.vlivetech.com"; //getText(R.id.userid);
        String password = "khubaib"; //getText(R.id.password);

        // Create a connection
        ConnectionConfiguration connConfig =
                new ConnectionConfiguration(host, Integer.parseInt(port),service);
        XMPPConnection connection = new XMPPConnection(connConfig);

        try {
            connection.connect();
            Log.i("XMPPClient", "[SettingsDialog] Connected to " + connection.getHost());
        } catch (XMPPException ex) {
            Log.e("XMPPClient", "[SettingsDialog] Failed to connect to " + connection.getHost());
            xmppClient.setConnection(null);
        }
        try {
            connection.login(username, password);
            Log.i("XMPPClient", "Logged in as " + connection.getUser());

            // Set the status to available
            Presence presence = new Presence(Presence.Type.available);
            connection.sendPacket(presence);
            xmppClient.setConnection(connection);
        } catch (XMPPException ex) {
            Log.e("XMPPClient", "[SettingsDialog] Failed to log in as " + username);
            xmppClient.setConnection(null);
        }

      return null;
    }

    @Override
    protected void onPostExecute(String result) {

    }
  }

Line on which i am getting an error in Async Task:

try {
            connection.connect();
            Log.i("XMPPClient", "[SettingsDialog] Connected to " + connection.getHost());
        } catch (XMPPException ex) {
            Log.e("XMPPClient", "[SettingsDialog] Failed to connect to " + connection.getHost());
            xmppClient.setConnection(null);
        }

why am i getting it? is there any problem with my host name? or port or something else? — Hassaan Rabbani, Mar 06 '14 at 12:55
May be yes, you can debug and check whether you are getting host name null or not. — Siddharth_Vyas, Mar 06 '14 at 12:57

If your NetworkOperation is inside your activity then remove this line from NetworkOperation or you might want to add a constructor(?), pass the xmppClient with the .execute()

private XMPPClient xmppClient;

Maybe you can use from this code .. and you don't need to AsyncTask ..

 String HOST = "Yourhost";
        int PORT = your port;
        String USERNAME = "USERNAME";
        String PASSWORD = "YOURPASSWORD";


            Thread t = new Thread(new Runnable() {
                @Override
                public void run() {

                    ConnectionConfiguration connConfig = new ConnectionConfiguration(
                            HOST, PORT);
                    connConfig.setReconnectionAllowed(true);
                    XMPPConnection connection = new XMPPConnection(connConfig);
                    try {
                        connection.connect();
                        Log.i("XMPPChatDemoActivity",
                                "Connected to " + connection.getHost());


                    } catch (XMPPException ex) {
                        Log.e("XMPPChatDemoActivity", "Failed to connect to "
                                + connection.getHost());
                        Log.e("XMPPChatDemoActivity", ex.toString());


                    }
                    try {

                        connection.login(USERNAME, PASSWORD);
                        Log.i("XMPPChatDemoActivity",
                                "Logged in as " + connection.getUser());


                        // Set the status to available
                        Presence presence = new Presence(Presence.Type.available);
                        connection.sendPacket(presence);

                        Roster roster = connection.getRoster();
                        Collection<RosterEntry> entries = roster.getEntries();

                    } catch (XMPPException ex) {
                        Log.e("XMPPChatDemoActivity", "Failed to log in as "
                                + USERNAME);
                        Log.e("XMPPChatDemoActivity", ex.toString());


                    }

                }
            });
            t.start();
