Apps GPS and reverse GeoLocation

[GIR]

Hello everyone,

Im still a bit green when it come to java programming but I've given this topic a good stab before asking

My goal is to collect the postal address based on GPS coordinates.

I have been going through the numerous tutorials but I seem to have reached an impasse: mapview is needed for reverse geo-location to work because it passes my google map API key for it to work.

Can anyone tip me to a Reverse Geolocation example that does not use the map view?

I use Ubuntu 10.04 and Eclipse Version: 3.5.2 Build id: M20100211-1343 and would like to target the 2.1 GoogleAPI.

Many thanks for any links, code samples, etc,
GIR

Ok,

Got it sussed out - its taken a lot of effort to suss the differences between the code samples out there on the internet, but after a lot of time I got it to work.

I had to to use API 4 because, for some reason not yet clear to me, 2.1 just wouldnt play ball - IF anyone can provide a reason why I'd be glad to hear it.
