Get Context in a Service

Question

Is there any reliable way to get a Context from a Service   I want to register a broadcast receiver for ACTION PHONE STATE CHANGED but I don t need my app to always get this information  so I don t put it in the Manifest    However  I can t have the broadcast receiver be killed by the GC when I need this information so I m registering the broadcast receiver in a Service    Hence  I need a Context to to call registerReceiver     When I no longer need the ACTION PHONE STATE CHANGED I unregister it   Any tips
