Hi. I’m trying to make a connection to my Openfire server running on my home computer using following code:

public class MainActivity extends ActionBarActivity {

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

ConnectionConfiguration connConfig = new ConnectionConfiguration(“192.168.0.101”, 5222, “home”);

XMPPConnection connection = new XMPPTCPConnection(connConfig);

try

{

connection.connect();

connection.login(“user”, “12345”);

}catch (Exception ex)

{

Log.e(“ERROR”, “Exception”, ex);

}

}

I’m getting followin stack trace

Hello,

here, I see two potentials error (I say potential because I’m a Smack beginner and I’m not sure of what I’m gonna say).

  • You should call SmackAndroid.init(Context) to make aSmack usable.

  • You should open the connection to the server in a AsyncTask.

Something like this:

private class OpenConnectionAction extends AsyncTask<Void, Void, Void>

{

@Override

protected Void doInBackground(Void… arg0)

{

SmackAndroid.init(getApplicationContext());

ConnectionConfiguration config = new ConnectionConfiguration(HOST, PORT);

config.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled);

connection = new XMPPTCPConnection(config);

try

{

connection.connect();

connection.login(“Admin”, “******”);

    }

catch (Exception ex)

{

connection = null;

}

return null;

}

}

And then, you just call it:

new OpenConnectionAction().execute();

I don’t know if it is the best solution but it worked for me.
