Hi, i’'m trying to listen for presence status
and with this code when a contact change his status nothing happend…
roster.addRosterListener(
new RosterListener() {
public void rosterModified() {
}
public void presenceChanged(String user) {
// If the presence is unavailable then “null” will be printed,
// which is fine for this example.
System.out.println("Presence changed: " + roster.getPresence(user));
}
});
