I am trying to use a third party SIP implementation in my Android app. Since I want to support version older then 2.3, I cant use the SIP framework build into Gingerbread.
Do I need a constantly running service that will listen for the SIP call?
As far as I know, services are not meant to be run constantly, and listening to events like incoming calls or SMS is done by the system itself, which will broadcast it system-wide. Please correct me if I'm mistaken.
