TelephonyRegistry

public class TelephonyRegistry extends ITelephonyRegistry.Stub
Since phone process can be restarted, this class provides a centralized place that applications can register and be called back from. Change-Id: I450c968bda93767554b5188ee63e10c9f43c5aa4 fixes bugs 16148026 and 15973975 by saving the phoneId of the registrant and then using the phoneId when deciding to to make a callback. This is necessary because a subId changes from to a dummy value when a SIM is removed and thus won't compare properly. Because SubscriptionManager.getPhoneId(int subId) handles the dummy value conversion we properly do the callbacks. Eventually we may want to remove the notion of dummy value but for now this looks like the best approach.
