First, I use android and spark communication , the android side, I log A user (andorid), and the addition of (spark) B user as a friend. When I use the A ---> RosterEntry.setName ("test"), RosterListener.entriesUpdated () does not detect this change in their own names . When I modified B in spark state. After , A -----> RosterListener.entriesUpdated () detects the change of the name A , the change in state B,My question is : why, when I change the name of A , RosterListener.entriesUpdated () can not detect changes in name.
