title: How would i interact between webserver and android application based on GPS locations?
body: <p>I want to develop an application for android that will enable user1 to input locations. 
  and then based on a user2 location that user2 locations will update.</p>
  
  <p>What would be the best way to store this data, holding it on a server?</p>
  
  <p>then what would be the best way for the user2 list of locations to be updated. Would the server take the friends gps location and then based on a certain radius return a list of locations from user1.</p>
  
  <p>This should be able to work for multiple users. Do you guys have any idea's (or is my idea ok). </p>
  
  <p>How would i go about doing this programmatically, i mean how would i interact with server and the android application. </p>
