There is a bit more to TelephonyManager than just monitoring phone state. > For example, you could create an incoming calls register implementing a > broadcastreceiver and using TelephonyManger API or extending > PhoneStateListener class and registering this new listener > through TelephonyManager .

Use the listener when you need to find out about the event only when your code is running (e.g., disable some menu choice in an activity). Use the broadcast Intent when you need to find out about the event when none of your code is running. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://github.com/commonsguy http://commonsware.com/blog | http://twitter.com/commonsguy Android Training in London: http://skillsmatter.com/go/os-mobile-server -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
