Tizen地图未显示

Question

我已添加了以下特权

<privilege>http://tizen.org/privilege/mapservice</privilege>
<privilege>http://tizen.org/privilege/internet</privilege>
<privilege>http://tizen.org/privilege/network.get</privilege>

#include <maps_service.h>
#include <maps_view.h>

我添加了非常简单的视图。我的应用无法正常工作。任何人都可以帮助我解决问题

Evas_Object *img = evas_object_image_filled_add(e);
evas_object_show(img);

/* Service also created */
error = maps_view_create(ad->maps_service_handle, img, &(ad->map_view_handle));
if (error == MAPS_ERROR_NONE) {
    /* Set a zoom level */
    dlog_print(DLOG_ERROR, LOG_TAG, "MAPS_ERROR_NONE");
    maps_view_set_zoom_level(ad->map_view_handle, 12);

    /* Create a coordinate and set it to center */
    maps_coordinates_h maps_coord;
    maps_coordinates_create(DEFAULT_LAT, DEFAULT_LON, &maps_coord);
    maps_view_set_center(ad->map_view_handle, maps_coord);
    maps_coordinates_destroy(maps_coord);
}
