title: How to load only markers that's currently visible on the screen (Google maps on Android)
body: <p>Using Google Maps on Android does anyone have any ideas on how to load only markers that would be displayed on the current screen?</p>
  
  <p>I'm thinking about sending a request to a web service that returns the lat/lng for the relevant markers. But what would the parameters be that I could use to calculate if a given lat/lng is within the screen?</p>
  
  <p>What would be perfect would be something like <a href="http://gowalla.com/api/explorer#/spots?lat=30.2697&amp;lng=-97.7494&amp;radius=50" rel="nofollow noreferrer">Gowalla's implementation</a></p>
  
  <p>Any ideas?</p>
