I am using group chat with openfire (MUC).
i can able to send messages but how to send file to group with Smack library.
i can able to send file to single user but i don't know how to send file to group chat (MUC) so all users in room will receive that file.
someone told me that use XEP-0066: Out of Band Data but he didn't told me how can use this.
Please Help.
