Android Smack Ejabberd multiple connection issue

Question

Im delveloping chat app using Ejabbered & smack on android client, Everytime user enters app I'm sending my presence as available to server & everytime user leaves app I'm sending the presence as unavailable so i can receive the offline messages which are sent after that.. But Though I send presence packet when leaving app, I can still see the user Online when i check from different client. Looking at logcat I suspect multiple connections are alive:

what is the mistake I'm making, I noticed in logcat of successful logout the number is always zero, n in unsuccessful one its upto 2 so am i creating multiple connections?? or the Number is not the no of connections?? if it is issue with number of connections How do I create a single n only instance till my app is alive??

Answer 1

You can shout down old instance before making connection That's may be help you .

if(mXmpptcpConnection!=null){
        mXmpptcpConnection.instantShutdown();
    }
