I have successfully created a multiuserchat group, but the user goes offline the user is removed from the group, and i want to have the history of messages to save for the user the next time he logs in. I found some approaches from previous and deduced as follows
- There are several old answers out there but none of them is based on new SMACK API 4.1.5+
- using "Stream Management", but i have no idea what and how to do it, How it helps to solve my problem.
- Using a PUBSUB for getting messages and delivering to user and showing the pseudo-list of users.
I want to know the best and effective approach or any libs which help to achieve my result. I am a newbie to XMPP and have 2+ year experience in java
NOTE: I am looking for a whatsapp group chat implementation to kick/invite/providing_permissions to the user and history of messages for notifications/when he is offline.
I am searching for this from long time , Any Help is really appreciated. Thanks in advance.
