Android Xmpp entriesAdded rarely called

When I add a user, that user does not call "entriesAdded"  I think it's listener problem or how to add users.

For example:

User2 -> Agree -> User 1

User 1 does not call the listener "entriesAdded"

The method, "entriesAdded" rarely called, why? What am I doing wrong?

roster.addRosterListener(newRosterListener(){
                        @Override
                        publicvoid presenceChanged(Presence presence){
                        system.out.println("1");
                    }

                    @Override
                    publicvoid entriesUpdated(Collection<String> arg0){
                        // Called when a roster entries are updated.
                        system.out.println("2");
                    }

                    @Override
                    publicvoid entriesDeleted(Collection<String> arg0){
                        // Called when a roster entries are removed.
                        system.out.println("3");
                    }

                    @Override
                    publicvoid entriesAdded(Collection<String> arg0){
                        // Called when a roster entries are added.
                        system.out.println("4");
                    }
                });
            }
        }
    });

What actually happens is that when I add or remove always called "entriesUpdated" ("2"), because rarely called ("4")?
