Android 如何使用位置信息在谷歌地图上创建路线？

我有一份申请。我有一个谷歌地图的位置信息。我想从使用谷歌地图的地方创建一条路径

 String url = "yandexmaps://maps.yandex.ru/?pt=" + routePlan.getLocationLat() + "" + routePlan.getLocationLong() + "&z=12&l=map";
        Intent intentYandex = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
        intentYandex.setPackage("ru.yandex.yandexmaps");

        String uriGoogle = "geo:" +routePlan.getLocationLat()+"," + routePlan.getLocationLong();
        Intent intentGoogle = new Intent(Intent.ACTION_VIEW, Uri.parse(uriGoogle));
        intentGoogle.setPackage("com.google.android.apps.maps");

        String title = "Select";
        Intent chooserIntent = Intent.createChooser(intentGoogle, title);
        Intent[] arr = new Intent[1];
        arr[0] = intentYandex;
        chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, arr);
        startActivity(chooserIntent);

谷歌为它提供服务。您可以使用谷歌地图sdk和谷歌的方向Api

只需向google的directions api发送一个http请求

https://maps.googleapis.com/maps/api/directions/outputFormat?parameters

它将返回一个json响应，如下所示：
