Question

I have this code that should place a marker on a map using LatLng

    ...
geocoder = Geocoder.create();
myOptions = MapOptions.create();        
myOptions.setZoom(18);
myOptions.setMapTypeId(MapTypeId.HYBRID);
myOptions.setMapMaker(true);
map = GoogleMap.create(
    Document.get().getElementById("map_canvas"),myOptions);  
location = LatLng.create(45.48592686713835,-73.49009937672122);
map.setCenter(location.getGeometry().getLocation());
marker = Marker.create();
marker.setMap(map);
marker.setPosition(location.getGeometry().getLocation());
    location = LatLng.create(45.48592686713835,-73.49009937672122);
    map.setCenter(location.getGeometry().getLocation());
    marker = Marker.create();
    marker.setMap(map);
    marker.setPosition(location.getGeometry().getLocation());

But instead I get an exception. It looks like that there is a %20 in the front of the Longitude

There is the StackTrace

Answer 1

map.Center() takes a LatLng, so you don’t need to do any conversion of an existing LatLng:

map.setCenter(location.getGeometry().getLocation());

should be

map.setCenter(location);
