Final Solution

Use reverse geocoding via the Google Geocoding API.

The term geocoding generally refers to translating a human-readable address into a location on a map. The process of doing the converse, translating a location on the map into a human-readable address, is known as reverse geocoding.

The Geocoding API supports reverse geocoding directly using the latlng parameter. For example, the following query contains the latitude/longitude value for a location in Brooklyn:

http://maps.googleapis.com/maps/api/geocode/json?latlng=40.714224,-73.961452&sensor=true_or_false

The docs explain how to interpret the json results but StackOverflow has various answers addressing more efficient ways to parse the data.

Possible Solutions

• Getting the nearest street/road coordinates in android - the answer to this question may point you in the right direction.

  You can use directions api directly: http://maps.googleapis.com/maps/api/directions/json?origin=51,19&destination=51,19&sensor=false

  Could you use the API to find directions which would then provide the closest road?
