Java – Google Maps Android api v2 polyline length

I’m trying to find the android maps api v2 method that will determine the length of the polyline I create when I move. I’ll put it in onLocationChanged() for continuous updates. Does anyone know what the method is and what units are in which the Maps API will display length?

Polyline line = map.addPolyline(new PolylineOptions());

public void onLocationChanged(Location location) {

line.add(new LatLng(location.getLatitude(), location.getLongitude())
 .width(5)
 .color(Color.RED));

}

I’m having the same issue. Here’s how I solved the problem.

1. private ArrayList<LatLng> mLatLngList;
   Add a location to the ArrayList when the location changes.
2. Use Gradle to import this http://googlemaps.github.io/android-maps-utils/ Library to your project or
   compile 'com.google.maps.android:android-maps-utils:0.4'

import

3. library import com.google.maps.android.SphericalUtil;
4. double distance = SphericalUtil.computeLength(mLatLngList);
