• I have solved my own question. Here is the code I ended up using.

  Titanium.Geolocation.purpose = "Recieve User Location";
  Titanium.Geolocation.accuracy = Titanium.Geolocation.ACCURACY_BEST;
  
  // Set Distance filter. This dictates how often an event fires based on the distance the device moves. This value is in meters.
  Titanium.Geolocation.distanceFilter = 10;
  //set the mapview with the current location
  var mapview = Titanium.Map.createView({
      mapType: Titanium.Map.STANDARD_TYPE,
      animate:true,
      region: {latitude:39.30109620906199, longitude:-76.60234451293945, latitudeDelta:0.1, longitudeDelta:0.1},
      regionFit:true,
      userLocation:true,
      visible: true,
  });
  
  function getLocation(){
  //Get the current position and set it to the mapview
  Titanium.Geolocation.getCurrentPosition(function(e){
          var region={
              latitude: e.coords.latitude,
              longitude: e.coords.longitude,
              animate:true,
              latitudeDelta:0.001,
              longitudeDelta:0.001
          };
          mapview.setLocation(region);
  });
  }
  
  win.add(mapview);
  
  Titanium.Geolocation.addEventListener('location',function(){
      getLocation();
  });
  

  I thought that downvoting my question was uncalled for since I've been looking for something near this code example for over a week. Hope it helps any other new developers in the future.

• I don't see any reason for down-voting of your question. So, I gave it an up-vote so you're back to zero.

  For other developers, make sure to check the Kitchen Sink for code examples. It doesn't always have everything, but it covers a lot of the basics.

  Finally, I'm not entirely positive, but your solution code might have some issues due to the fact that the geolocation functionality is asynchronous. Just because you call getCurrentPosition() doesn't mean you'll immediately get new coordinates. Your mapview.setLocation(region) call could end up with old values, or I suppose even null values.

  You might want to wrap that call in a try/catch block or something to make sure that you don't cause an error.

• Anyone have the final code as im too having problem with the async function. I would like to create a button that can reposition the map to user current location. Can anyone shed some light? Thanx

• Hi Hector, I was looking through and running into the same problem with my geo location. I was curious if you had any break throughs with it and maybe could share with me what you had done to achieve this. Thanks for your help! -paul
