I need to find all cities, towns or postal codes in radius of 20 km from place specified by latitude and longitude.
I've tried Places search from Google Places API with this query:
https://maps.googleapis.com/maps/api/place/radarsearch/json?location=53.09022140,21.21483510&radius=20000&types(locality|postal_code)&sensor=false&key=myKey
but this seems not to work with geocode places (only business results are presented).
I've also read about Place Searches in Places Library of Google Maps JavaScript API v3, but I'm not sure if this is appropriate for Android Application (I have a http/php server, but I'm not sure how can I use it with my Android App). Can I use it directly from my application?
Maybe I could achieve it using other service? Do you have any suggestions?
