I would like to use an API (preferred to be google maps if it's supported) in my android application to pass the longitude/latitude of a location and the API returns the city name.
In the solution to this, you should go for getAddressLine(x)

i believe google does provide what you are requesting here http://code.google.com/apis/maps/documentation/geocoding/#ReverseGeocoding

I believe that the APIs are rate limited. i.e you cannot hit the API for more than a number of times in a hour.. Android contains a Geocoder class which does ReverseGeocoding as well.. Take a look at this link.

Thanks, I think this is what I need. I'm going to test it now. – mohamede1945 Jul 17 '11 at 12:42

I tested it, but I cannot use it to get the city. Do you know a way to do this? – mohamede1945 Jul 17 '11 at 12:55

You need to have the internet permission in the manifest. `Geocoder geocoder = new Geocoder(this, Locale.getDefault()); List addresses = geocoder.getFromLocation(lat, lng, 1); addresses.get(0).getLocality();` Locality should give you the city. – Varun Jul 18 '11 at 06:40

Thanks Varun! I already have the internet permission. But it gives me null. – mohamede1945 Jul 18 '11 at 12:15

possibly the lat/long are invalid. you can enter the lat/long on the google maps on the desktop browser and confirm that there are results for the lat/long values. – Varun Jul 18 '11 at 16:17

Here is the code I use Geocoder geocoder = new Geocoder(this); Address a = geocoder.getFromLocation(33.035810, -96.704071, 1).get(0); I don't think the lat/long are invalid, do you think? – mohamede1945 Jul 20 '11 at 01:13

tried this on the google maps. Seems to be valid. are you testing on a device/emulator. that could be a prob, not sure.. I had always tested the goecoding/reverse geocoding on a device and always got this working. There should be something very small which is missing in here.. – Varun Jul 20 '11 at 06:09

`07-20 14:52:22.820: VERBOSE/TAG(2921): Address[addressLines=[0:"2800 N Central Expy",1:"Plano, TX 75074",2:"USA"],feature=2800,admin=Texas,sub-admin=null,locality=Plano,thoroughfare=N Central Expy,postalCode=75074,countryCode=US,countryName=United States,hasLatitude=true,latitude=33.0356359,hasLongitude=true,longitude=-96.703987,phone=null,url=null,extras=null]` i tried the same code and the result i got it above... What is the target you tested on.. or which device? – Varun Jul 20 '11 at 09:24

Geonames.org is another. Here's a sample API call to find names near Seattle:
