ConverserActivity.java

// as part of an activity. In the code snippet below, it shows useful
// places to put the code so that it is initialised and subscribes at
// the right time.

        // this doesn't actually connect to the server, it just sets it up ready to go for the 
        // subscription later on when the activity starts.

        // to check the inbox and see if there's anything to grab.
