Как использовать kml файл на mapView в Android

Мне было интересно, как загрузить уже созданный kml файл в mapview программно? Файл kml хранится в SD-карте. У меня уже установлен mapActivity. Я просто SAX разбираю файл kml и использую метод draw для создания границы? Вот фрагмент файла kml, хранящегося на телефоне
