Answer 1

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());
}

Thanks,butin which i can determine status online or offline can u clear this? – Uzzia

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? – Araceli

Same here. I just get the status unavailable :/ – Sirkin

'xmppConnection.getRoster()' is not giving the updated roster entries. Have any idea about that? – Mcmann

    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.

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

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) {
