addRoute on android and sdk 2.1

Hi there!

with the announcement of sdk 2.1, the titanium team announced that there is a "addRoute" method for android as well. But when I switch to 2.1 in my tiapp.xml and try to add a route, I still get the message that my mapviewobject does not have such a method.

Here is the Code:

map.addRoute({
            color : 'purple',
            name : 'route',
            points : points,
            width : 5
        });

Best Regards, Martin
