I am looking for an android app that could be used to track some smartphones, for research purpose. There are apps such as Family Locator, etc. However, these apps can only show you the visual location on the map.
I want to log and record the actual GPS coordinates into a server. (perhaps sending data using AJAX? Right now, we have a server which accepts AJAX request and just log the incoming data) Is there a utility app that allows for such level of customization?
If anyone got other suggestion or other possible methods for "logging GPS coordinates from many smartphones and sending them to a server in realtime", please suggest me.
