前言：最近做一款外卖配送的应用，需要直接打开第三方地图，简单记录下

• 需要条件编译哦，只有app端可以呀，小程序不支持哦
• 小程序的打开第三方地图需要依托于uni.openLocation，不过这样会先打开地图页，然后右下角会有选择打开第三方图片的按钮

//打开第三方地图
export function openMap(latitude,longitude,name){
    let url = "";
    if (plus.os.name == "Android") {
        let hasBaiduMap = plus.runtime.isApplicationExist({
            pname: 'com.baidu.BaiduMap',
            action: 'baidumap://'
        });
        let hasAmap = plus.runtime.isApplicationExist({
            pname: 'com.autonavi.minimap',
            action: 'androidamap://'
        });
        let urlBaiduMap = `baidumap://map/marker?location=${latitude},${longitude}&title=${name}&coord_type=gcj02&src=andr.baidu.openAPIdemo`
        urlBaiduMap = encodeURI(urlBaiduMap)
