title: Android: How can I get the current foreground activity (from a service)?
body: <p>Is there a native android way to get a reference to the currently running Activity from a service?</p>
  
  <p>I have a service running on the background, and I would like to update my current Activity when an event occurs (in the service). Is there a easy way to do that (like the one I suggested above)?</p>
