Basiclly on the onTap method I want to :
1. Know the value of latitude and longitude which I'm tapping
- I can get this by GeoPoint geo=item.getPoint(); and taking the lat/
long out of it
2. Perform an HTTP request to a server that delivers me a lat/long
3. If the lat/long from the server are the same as the ones from that
point I execute another command that shows me the picture.
Basiclly is a sort off hit test comparison.
The overlays are created from the lat/long of the server in the first
place so I should be dealing with same values,
but I'm dealing with latitude/longitude values that are being
automaticlly converted for example:
The longitude that creates one of the Geopoint retrieved from the
server is : -16.9073252
The longitude from the actual GeoPoint that was created is : -16.907326
So when I compare them, they are not the same, obviously, and my
picture isin't shown.

My question is... is it possible to know exactly from which GeoPoint
( in this case Y ) the overlay was created?
Why does this matter? The overlay item has a point attached to it
with the location.
... I want to perform an HTTP request from onTap on which I compare
the lat/long of the overlay with the lat/long of the place the user
tapped... but I can't seem to get the numbers right..
What numbers?
longitude and latitude suffer approximations during the convertions
which is making my job impossible..
What conversions?
so if I have access from the onTap method to the actual GeoPoint
that ''created'' that overlay I could compare them...
The GeoPoint that "created" the overlay is attached to the overlay
item, isn't it? And compare what?
