How to implement real-time UI updates in Android---need to consider power and traffic

This is done by separating the life cycle of the handler from the activity and providing an interface to the handler, each activity being a listener, notifying the activity when the handler data changes

Then in the activity to implement the interface, re-interface inside the method, in the Onresume register, in the OnPause inside write-off,
