go4.setName («Image from assets»);
sharedWorld.addBeyondarObject (go4);
По умолчанию для контейнера World и для его объектов, в классе CustomWorldHelper, задаются фиксированные координаты в реальном мире. Исправим это, привязав координаты контейнера World к местоположению устройства.
Для определения местоположения устройства используем Fused location provider API (Android API Level> v9, Android Build Tools> v21).
Изменим код классов CustomWorldHelper, GoogleMapActivity и SimpleCameraActivity.
