Как использовать OpenStreetMap / OpenLayers?

/ 12 ноября 2011

Я ищу пример использования OpenStreetMap с PhoneGap и Android.
Я нашел только старые примеры в Интернете, например http://mab.edina.ac.uk/geomobile-test/osm.html, но он не работал с новейшим PhoneGap, я следовал учебному пособию в PhoneGap.

Я получил следующую ошибку, возможно кто-то запустил ее (исправлено) :

Спасибо за любые советы.

Когда я удаляю 50000 и передаю только один параметр loadUrl, сбой исчезает. Кажется, может быть проблема с параметром timeout в 1.2.
