Hi Dharmesh We had a database provided by company storing restaurants details by their latitude and longitude. We have created a service to get the list of retardants by adding a little margin to current latitude and longitude of the person searching Ex: if my latitude is 29 and longitude is 72 I get the list of restaurants with latitude lying in between 28.5 to 29.5 and same for longitude between 71.5 and 72.5 That list I was binding in the list adapter and showing them on screen. Even all the restaurants was plotted on the Google map also

Hi Dharmesh refer this http://www.shabdar.org/asp-net/70-google-maps-control-for-aspnet-part-1.html You need to find your latitude and longitude and then in your data base you should have the list of restaurants with their latitude and longitude. Add a fix amount to your latitude and longitude and pick all the restaurants in that range and show them. I have developed a similar app but in android. The app name is Epicurean.
