Calculate the area covered by a polygon in a google map in an Android App

Issue

I've got a series of Location / GeoPoint objects that form a polygon in my Android app. I wonder if there's any way to calculate the area covered by it.

So far I'm thinking about setting up a web service that, when posted the list of coordinates, uses the JS Google Maps API v3 to calculate the area. But there might be a way of doing this easily with some feature from Android I don't know about, natively.

Thanks in advance for your help!
