title: Do I really have to use an Activity class to launch my Service
body: <p>Creating an Activity with a Service and setting up the bindService.
  I thought i could make all this run "hidden" like a background Service - silentely this Service (client) would connect to my PC server waiting for incoming. I read the Service class api dock and cant see any description how to do that. Do I really have to use an Activity class to launch my Service. I know i can launch activity classes from the service if I need.
  Can somebody enplane this before i go nuts?</p>
