Question

I have an application with several activities and I want to be notified when the phone goes online (doesn’t matter which activity is the user in). I’ve found a Broadcast Receiver to do it, but I’d like to know if there is a way to declare this BroadcastReceiver only once, I want to avoid having to place the code in each activity (I have more than 20 activities!).

Thank you.

Answer 1

Create a parent abstract class which extends Activity and define the broadcast receiver implementation there. Later, modify your activity classes to extend that parent class.
