Get the distance between two locations in android?
Use the Google Maps Directions API. You'll need to request the directions over HTTP. You can do this directly from Android, or via your own server.
For example, directions from Montreal to Toronto:
GET http://maps.googleapis.com/maps/api/directions/json?origin=Toronto&destination=Montreal&sensor=false
You'll end up with some JSON. In routes[].legs[].distance
, you'll get an object like this:
"legs" : [
{
"distance" : {
"text" : "542 km",
"value" : 542389
},
You can also get the polyline information directly from the response object.
As Chris Broadfoot is correct, to parse returned JSON routes[].legs[].distance
"legs" : [
{
"distance" : {
"text" : "542 km",
"value" : 542389
}
Use:
final JSONObject json = new JSONObject(result);
JSONArray routeArray = json.getJSONArray("routes");
JSONObject routes = routeArray.getJSONObject(0);
JSONArray newTempARr = routes.getJSONArray("legs");
JSONObject newDisTimeOb = newTempARr.getJSONObject(0);
JSONObject distOb = newDisTimeOb.getJSONObject("distance");
JSONObject timeOb = newDisTimeOb.getJSONObject("duration");
Log.i("Diatance :", distOb.getString("text"));
Log.i("Time :", timeOb.getString("text"));
