Hello, i have a problem with my mapView. my app reads "some" gps points out of a file and i want to draw a route (drawing lines between the gps point). If my file contains many gps points, my app works really slow. i think its working slow, because i draw all overlays. now i want to check, whether a point is visible in my mapView or not. so i have to get the mapCenter and Lat/lon span (getLatitudeSpan,..) !? how and where must i save my points and how can i check all my points (after my mapCenter has changed for example). Shall I save my points in a list (in my Overlay class??) and iterate through every list item and check, wheter its visible or not??
