Android Background Runnable not working on older devices

Question

I have the following running at startup inside of an IntentService

threadManager.postBackgroundRunnableDelayed(() -> {
            try {
                // Calling getToken and getId must be on separate thread. Otherwise, it blocks UI thread.
                String token = instanceID.getToken(SENDER_ID, GoogleCloudMessaging.INSTANCE_ID_SCOPE);
                String id = instanceID.getId();
                Timber.d("id: " + id);
                Timber.d("token: " + token);
                lazyRestQueue.get().sendGcmToken(new GcmPushRequest(id, token), getSendGcmTokenCallback());
                setupAnalytics(token);
            } catch (IOException e) {
                Timber.e(e, "Exception during registration");
                Crashlytics.logException(e);
                setHasToken(false);
            } catch (RuntimeException e) {
                // This will be thrown if Localytics was not properly setup
                Timber.e(e, "Exception during registration");
            }
        });

When I run it on anything below API 18 it causes the app to close (not crash oddly, just close)

can someone give me advice on this? I know it probably has to do with the service or something not timing properly
