title: Updating Activity TextView from service using Service binding
body: <p>I have a service for reading GPS latitude and longitude. I would like to update the activity from the service's <code>locationlistener</code>'s <code>onLocationChanged</code>.</p>
  
  <p>How can I achieve it? I have been reading on <a href="http://developer.android.com/guide/components/bound-services.html#Binder" rel="noreferrer">Service Bound</a> but it looks like it is only for activity to invoke the methods in service but not service invoke textView in Activity. Is binding service is not possible to achieve it? </p>
