I have a list of registered users . I want to compare their location with the current user . I know I need to send the location coordinates periodically to the server. This would be done within a service . I am not sure at what time I should obtain the location coordinates of the users :- At the registration time or login time.
Please provide me some suggestions what is the right time to save the location details into the server.
I am new to android. (Pardon me if this is something silly I am asking for).
