API to pass lon/lat and return city name

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 r开发者_运维知识库eturns the city name.

In the solution to this, you should go for getAddressLine(x)

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.

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

Geonames.org is another. Here's a sample API call to find names near Seattle: http://api.geonames.org/citiesJSON?north=47.65&south=47.55&east=-122.30&west=-122.40&lang=de&username=demo
