I am using these libraries
How can I set TTL for every message from Android Application?
What should happen if the TTL expires?
I want to use that TTL in xmpp server to delete it. As saw this link http://xmpp.org/extensions/xep-0023.html
There is XEP-0079: Advanced Message Processing 's expire-at and Smack has support for XEP-0079.
