@Flow I am working on an Android and iOS app, I am using XMPP protocol and Open Fire for Peer to Peer chat and its working fine.
But now I am working on Group Chat, and stuck at Offline Message section.
- I need to understand how to figure out which user in the group is offline?
- How to target offline users and send them the notification of the message?
- How to get the total unread messages if the user is offline?
- How to get the history of the Group if the user comes online after a long time?
Let me know how to resolve this.
or else let me know if you need any more information.
