Roster roster = xmppConnection.getRoster();
Collection<RosterEntry> entries = roster.getEntries();
Presence presence;

for(RosterEntry entry : entries) {
    presence = roster.getPresence(entry.getUser());

    System.out.println(entry.getUser());
    System.out.println(presence.getType().name());
    System.out.println(presence.getStatus());
}

I did the same code but every user simply gives presence "unavailable" how it can be when there are 4-5 already available, but showing me all are unavailable can anyone help me on that? – mayank_droid Feb 28 '12 at 11:06

Same here. I just get the status unavailable :/ – Muten Roshi Oct 18 '14 at 13:25
'xmppConnection.getRoster()' is not giving the updated roster entries. Have any idea about that? – arjun Aug 22 '15 at 09:35

    XMPPConnection.addConnectionCreationListener(new ConnectionCreationListener() {

        @Override
        public void connectionCreated(Connection arg0) {
            Log.i(TAG, "receive xmpp connection : " + arg0);
            connection = arg0;
            roster = arg0.getRoster();

            Collection<RosterEntry> entries = roster.getEntries();
            Presence presence;

            Log.e(TAG, "user count" + entries.size());

            for (RosterEntry entry : entries) {
                presence = roster.getPresence(entry.getUser());

                Log.i(TAG, "" + entry.getUser());
                Log.i(TAG, "" + presence.getType().name());
                Log.i(TAG, "" + presence.getStatus());
            }

        }
    });

So at the start of your program register that XMPPConnection listener, usually it take few seconds to receive connection object. But it will work only if you will use creatEntry only in that case rooster will see those created users.

To creat entry using Roster use next code:

try {
    rooster.createEntry("name", "user_id", null);
} catch (XMPPException e) {
    e.printStackTrace();
}

I didn't use any group, and with success see user on second device.

Presence presence = roster.getPresence("tom@jabber.org");
if (presence.getType() == Presence.Type.AVAILABLE) {
   // Tom is online...
}

smackAndroid = SmackAndroid.init(this);
XMPPConnection.addConnectionCreationListener(new ConnectionCreationListener() {

    @Override
    public void connectionCreated(XMPPConnection connection) {

          Log.i("hello", "receive xmpp connection : " + connection);
          roster = connection.getRoster();

          try {
              roster.createEntry("2868254", "hello", null);
          } catch (XMPPException e) {
              e.printStackTrace();
          } catch (NotLoggedInException e) {
              // TODO Auto-generated catch block
              e.printStackTrace();
          } catch (NoResponseException e) {
              // TODO Auto-generated catch block
              e.printStackTrace();
          } catch (NotConnectedException e) {
              // TODO Auto-generated catch block
              e.printStackTrace();
          }
      }
});

Can you add some explanation to this? – apaul Apr 25 '15 at 16:02 — apaul, Apr 25 '15 at 16:02

Use the presence.getMode() method to get Mode of User. Mode is enum and its value can be chat, available, away, xa, dnd.
