hi i’'ve a small question about sending messages:
i toy with the idea of implementing a whiteboadr application using the xmpp protocoll as transfere layer and so smack as layer for sending the message.
now my problem: i saw that i can add arbitrary properties to messages (as it can be found in the api documentation) and it would be no problem to add the informations i need for the whiteboard to one of these messages but … and that’'s the difficult part.
if anyone sends such an message to a client that doesn’‘t understand the whiteboard messages i don’'t want it to display anything (and not an empty message) - is this possible or has anyone an idea how i can realize that?
