核心代码

检索建筑物数据（需开通高级权限才可使用）

JAVA

/**
LatLng requestLatlng = new LatLng(23.008468, 113.72953);

private void searchBuilding() {
    BuildingSearchOption buildingSearchOption = new BuildingSearchOption();
    buildingSearchOption.setLatLng(requestLatlng);
    mBuildingSearch.requestBuilding(buildingSearchOption);
}
