I want to show a route between two points in Google Maps V2. I am able to achieve this with V1 but Google Map V2 does not support geopoints. So what should I do?
You can draw Polylines for routes. Docs here:

If you mean drawing an actual route that you see in Google Maps directions, read the discussion here. Basically you'll need to utilize DirectionService
