title: LocationManager calling onLocationChanged too often?
body: <p>I've set up the LocationManager to get the current location every 2 minutes:</p>
  
  <pre><code>locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 120000, 0, this);
  </code></pre>
  
  <p>This works fine and onLocationChanged is called every 2 minutes as expected. However, it seems that it is being called multiple times over a 10-40 (a random amount) second span <em>every</em> 2 minutes. I log every location received in the onLocationChanged so here are some samples to get an idea of what is going on:</p>
  
  <p>At 17:30</p>

  <p>And so on... then another set of updates 2 minutes later at 17:35.</p>
  
  <p>Is this the standard behavior? I was expecting to get only <em>one</em> location every 2 minutes, and the timespan in which it gives me location updates seems rather random. Ideally I would prefer to only get one location... is there a way to do this?</p>
