New approach that makes more sense:
int latSpan = mapView.getLatitudeSpan();
int longSpan = mapView.getLongitudeSpan();
GeoPoint mapCenter = mapView.getMapCenter();
int topLatitude = mapCenter.getLatitudeE6() +
(latSpan/2);
int bottomLatitude = mapCenter.getLatitudeE6() -
(latSpan/2);
int leftLongitude = mapCenter.getLongitudeE6() -
(latSpan/2);
int rightLongitude = mapCenter.getLongitudeE6() +
(latSpan/2);
But this values:
int latSpan = mapView.getLatitudeSpan();
int longSpan = mapView.getLongitudeSpan();
are giving me 36000000 and 0 :/

Exactly. You need to pass the neLatitude, neLongitude, swLatitude,
swLongitude as query parameters to your back end web service, which
then returns only POIs whose latitude and longitude fall within those
bounds, like this Javascript Google Map does:

Notice that it even handles panning and zooming.
