Just have question about best approach to use, I need to send query from my device to other device to get the current location, so I think I have two choices.
The first is using sockets.
Or push notification.

The idea is to to send query to start service to get the current location of the user.
Also using services, not sure if it is the best choice.
the user I will get his location I don't want him to see anything, all work will done on background.

thank you.
