Thanks Mark, I no sure about the difference between registering the event on the activity or registering it on the application context, can ´t I pass the broadcastReceiver object thought onRetainNonConfigurationInstance() if I made it on the activity?
Another problem would be what happends if I have another listener (i.e. GPS location update listenes) in the same activity, with this solution is not posible to pass 2 different objects(listeners) to the onRetainNonConfigurationInstance, any solution? Thank you so much.
