Merge "Clear binder calling identity before calling callback" into sc-dev

        IOnSubscriptionsChangedListener callback = new IOnSubscriptionsChangedListener.Stub() {

            @Override

            public void onSubscriptionsChanged () {

                final long identity = Binder.clearCallingIdentity();

                try {

                    executor.execute(() -> listener.onSubscriptionsChanged());

                } finally {

                }

            }

        };

        mSubscriptionChangedListenerMap.put(listener, callback);
