I'm using Google Maps Android API v2 and a polygon drawn on maps. Now I want to calculate the area of this polygon.

I know that Google Maps JavaScript API v3 has a simple way to do this, using: google.maps.geometry.spherical.computeArea(yourPolygon.getPath()).

Is there a similar way to calculate polygon area using Google Maps Android API v2? If no, wich method do you suggest?

Thanks in advance.

Best regards.

EDIT:

I found the following algorithm that seems to resolve my problem:

I guess you will have to do some math. There doesn't seem to be a method for that in the Google Maps Android API v2.

Check the following questions for possible help:
