I am building an application in android using eclipse, where i have to choose a set of locations among a collection stored in database based on user's current location and distance at run time and display the co-ordinates on map.
I'm using google map v2 libs.
So basicaly how should i estimate the co-ordinates? How to retrieve the set of co-ordinates using query? How to handle the distance of available co-ordinates from user's current location eg. user wants all Hospitals within 1 KM radius.
Any help is appriciated thanks!!!
