title: Run start service when application starts and run across multiple activities
body: <p>I want to write an android service that will run with an app.  I want to run this service across multiple activities and have the ability to pass information back to the UI with all activities, not just the activity that starts the service. </p>
  
  <p>From what I understand, I have call <code>startService</code> and not bind it to the activity. Is this correct?</p>
  
  <p>Also, I do not want to start a new instance of the service, I want to use the same instance. If i call <code>startService</code> in each activity, will that use the same, running instance of the service?</p>
