LatLng を使用して地図上にマーカーを配置するこのコードがあります

    ...
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());

しかし、代わりに例外が発生します。%20経度の手前にがあるようです

map.Center()を取るLatLngので、既存の を変換する必要はありませんLatLng:

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

する必要があります

map.setCenter(location);

このスクリプトを使用すると役立つ場合があります。わたしにはできる..
