  <p>initList and initListWithoutDistance are 2 function that sort result by distance or name.</p>
  
  <p>When the GPS is active, I got no problem.
  When the GPS is off, and I click on "OK" button, I can't instantly get the current location. I tried to get the event onLocationChanged by calling <strong>location = locationManager.getLastKnownLocation(provider);</strong> , but the result is null. I can't call directly the function onLocationChanged because I got no location object.</p>
  
  <p>After several seconds (sometimes 2, sometimes 20...), the event is launched, and the result is tried.</p>
  
  <p>Is there a way to force this event, and to get the current location instantly after the user click on the "OK" Button?</p>
