Hi!
I'm trying to use Geocoder.getFromLocationName() with a bounding box,
but:
* On 1.5 I get lots of results outside of my box.
* On 1.6 I get no results at all.
How should I use Geocoder.getFromLocationName() with a bounding box so
that I get results inside of the box but not outside of it?
Here's what I'm trying to do. The example address "Storgatan 5" is
very common in Sweden and exists in lots of cities, so it's a good
test case. The bounding box covers the Stockholm area:
/**
* Try to find Storgatan 5 in Stockholm using {...@link
Geocoder#getFromLocationName(String, int, double, double, double,
double)}.
* <p>
* On 1.5, this example finds tons of "Storgatan 5"s, none of them
inside the
* box unfortunately.
* <p>
* On 1.6 I get no results at all from this code.
