I have read some posts that you can use iBeacon with Xamarin to detect when you walk by a beacon and have the app popup and go from there. I am new to this sort of concept. Is the app always running in the background to listen for the beacon? Or is it something that is setup with the device and calls the app to load when near one?
I also need an Android app version of this as well. Honestly I am new to Xamarin and have been using Corona Labs for the last few years. So to do this I will probably end up paying someone to write the basic parts of it for both iOS and Android. But I was just trying to understand how this works.
