How can I determine if a geopoint is displayed in currently viewable area?

Issue

Say I have mapview control in my Android app. If I know a landmark exists at a certain latitude and longitude, how can I determine if that landmark is currently viewable on the user's screen? Is there a method for getting the coordinates for the top left and bottom right corners of the visible area?

Solution

You can project GeoPoint to Point and check if it is box (0, screen width) by (0, screen height)
