调起百度地图功能介绍
鸿蒙版百度地图SDK提供简单的接口用来调起百度地图客户端（Native）来实现复杂的业务逻辑。支持的调起类型有：主图、标注、反GEO、POI检索（POI详情检索、POI周边列表检索）、两框、路线规划（步行路线规划、骑行路线规划）、导航。
当手机中安装了百度地图客户端APP（版本号为1.0.0以上），开发者可以通过BaiduMapRoutePlan类中的openBaiduMapHomePage(主图)、openBaiduMapMarkerPage(标注页)、openBaiduMapGeoCoderPage(反GEO页)、openBaiduMapRoutePage(两框页)、openBaiduMapDirectionPage(路线规划页)、openBaiduMapBusNearbyPage(公交附近页)，BaiduMapPoiSearch类中的openBaiduMapPoiDetailsPage(POI详情检索页)、openBaiduMapPoiSearchPage(POI列表检索页)、openBaiduMapNearbySugPage(发现周边页)，BaiduMapNavigation类中的openBaiduMapNaviPage(导航) 、openBaiduMapWalkNavi(步行导航页)、openBaiduMapBikeNavi(骑行导航页)、openBaiduMapTruckNavi(货车导航页)相关方法设置调起百度地图APP。如果未传入的坐标类型，则使用百度地图SDK的全局坐标类型。
注：通用参数和接口参数参考接口说明中鸿蒙端参数说明填写（https://lbs.baidu.com/faq/api?title=webapi/uri/harmony）
