I have this seemingly simple class in my app. All it does it add a circle to the mapView
at my Location
with the circle color depending on the CDMA signal Strength
at the location. Or that's what it's supposed to do. The app works fine if I only ask for one circle and the location with the cdma signal but it doesn't work in the if Statement format, even if there is only one else if
present. My question is why and if It has anything to do with how many times maps can be called at once. And If anyone knows a workaround, it would help a lot.
