Proximity Alert for location coordinates stored in server

问题

I am new to android programming. I want to make an app that can create proximity alerts based on the location coordinates stored in a server, that is compare user's current location with those stored in server and generate an alert if the location is within a particular radius. Is there any way to create proximity alerts for locations stored in a server ? Or is there any better approach for this problem ?

Thanks

In android its quite simple to do that.

Please, take a look at this class

http://developer.android.com/reference/android/location/LocationManager.html

especially at this method:

  addProximityAlert(double, double, float, long, android.app.PendingIntent);

this is exactly what you need.

The android SDK docs are really well done. Take always a look there ! :D
