How to handle multiple destination in Baidu Map using URI in Android/IOS

Question

We are integrating Baidu map and wants to show multiple stoppages (destinations) over the map. We have gone through official documentation of Baidu maps(http://lbsyun.baidu.com/index.php?title=uri/api/android) and found a parameter named 'viaPoints'. As per document, we need to pass JSON in viaPoints key but we are unable to append JSON in URL.

In android we are passing like this :

Intent i1 = new Intent();
i1.setData(Uri.parse("baidumap://map/direction?mode=driving&destination=上上&origin=西二旗&src=push&viaPoints={viaPoints:[{name:Beijing West Railway Station, lat:39.902463,lng:116.327737}]}"));
startActivity(i1);

We want to achieve multiple destinations as shown in attached image.

Answer 1

Although the documentation you mentioned looks to be in Chinees but got an idea.

You are not using double quotes around the array viaPoints and other keys in the JSON parameter.

JSON needs to be in this format

{
  "viaPoints": [
    {
      "name": "Beijing West Railway Station",
      "lat": 39.902463,
      "lng": 116.327737
    }]
}

Try this

i1.setData(Uri.parse("baidumap://map/direction?mode=driving&destination=上上&origin=西二旗&src=push&viaPoints={\"viaPoints\":[{\"name\":\"Beijing West Railway Station\", \"lat\":39.902463,\"lng\":116.327737}]}"));

   // Instantiates a new Polyline object and adds points to define a rectangle
PolylineOptions rectOptions = new PolylineOptions()
        .add(new LatLng(37.35, -122.0))
        .add(new LatLng(37.45, -122.0))  // North of the previous point, but at the same longitude
        .add(new LatLng(37.45, -122.2))  // Same latitude, and 30km to the west
        .add(new LatLng(37.35, -122.2))  // Same longitude, and 16km to the south
        .add(new LatLng(37.35, -122.0)); // Closes the polyline.

// Get back the mutable Polyline
Polyline polyline = myMap.addPolyline(rectOptions);
