Hi there could you be more specific on what you trying to achieve? It is normal when you offline you are leaving the room. For my case, I use openfire as my xmpp server when i joined a room i save the room data in database then once when i am online back i join back to the room and add message listener based on the info in database. Openfire will send you back the chat history once you join the room. This is feature can be change at Openfire console. Hope this help you =)
