mainactivity.java

you should work in intentservice's onhandleintent(), not in oncreate(). reason because intentservice stops haven't supplied code onhandleintent(). intentservice shuts down when onhandleintent() finishes , there weren't other startservice() calls.

in case, though, calls pubnub api asynchronous , therefore happen in background. maybe don't need intentservice here @ all. if want create model object keep data survive activity's configuration changes, consider using headless fragment or plain service.
