I have integrated the Smack library (xmpp client) to my android project (using the instruction as specified in https://github.com/igniterealtime/Smack/wiki/Smack-4.3-Readme-and-Upgrade-Guide, gradle method). However, there is some change in our system, that i have to forked the current Smack repo on github, and made some modification. The question is, now, how do i integrate those changes in my current project?
