I use Smack to exchange xmpp messages, on the OpenFire server OpenFire created two users, created the Friends group and added these users to this group.

Now on the phone I want to get a list of users in Roster , for this I use the following code:

  Roster roster = Roster.getInstanceFor(connection); Collection<RosterEntry> entries = roster.getEntries(); Presence presence; for(RosterEntry entry : entries) { presence = roster.getPresence(entry.getUser()); Log.e("Users in roster ", entry.getUser()); Log.e("Name of user in roster ", presence.getType().name()); Log.e("Status in roster", presence.getStatus()); }

I get the size of the entries zero. Accordingly, the log does not display the name of users who are in the roster . Why is roster size zero? How to get users who are in the roster ? Both users are online. I can send a message to the user (for this I exclude problems with connection).

I also want to add that in OpenFire itself in the OpenFire section I see a user who is in the roster :

  • And mod_roster is enabled in the mod_roster ? - Suvitruf ♦
  • @Suvitruf mod_roster is a plugin? If this is a plugin, then I do not see it on the official OpenFire website. - Lucky_girl
  • My mistake. With ejabberd mixed up. - Suvitruf ♦
  • And when you connect to one of the public servers, a similar situation occurs? - post_zeew

Creating users on the server and adding these users to some group does not entail changing the rosters of these users.

Creating a user on the server is, formally speaking, simply adding a username / password pair to the database, after which the user can log in with this connection on this server.

You need to add a contact to the roster of a specific user. I don’t know for sure if it is possible to edit a roster of a certain user with OpenFire tools (but most likely it is possible), but you can simply log in from a client (for example, with Xabber) under a certain user and client’s tools to add contacts to the roster of a logged in user.

After this procedure, the user's roster will change, and, most likely, you will see the added contacts.
