android - Firebase Network Dispatcher 在应用关闭后停止工作。但是 GCM 网络管理器非常适合上述场景

Question

我有一个场景，即使应用程序关闭，我也必须收听 XMPP 连接状态。现在我正在使用 Firebase Network Dispatcher，因为 GCM 网络管理器已被弃用，它仅在应用程序处于前台/后台时才有效。只要应用程序关闭，它就会停止。任何人都可以有建议吗？下面是我的代码片段。

    Driver driver = new GooglePlayDriver(getApplicationContext());
    FirebaseJobDispatcher firebaseJobDispatcher = new FirebaseJobDispatcher(driver);

    Job constraintReminderJob = firebaseJobDispatcher.newJobBuilder()
            .setService(FirebaseService.class)
            .setTag("Notify Tag")
            .setLifetime(Lifetime.UNTIL_NEXT_BOOT)
            .build();
    firebaseJobDispatcher.schedule(constraintReminderJob);

Driver driver = new GooglePlayDriver(context);
        FirebaseJobDispatcher firebaseJobDispatcher = new FirebaseJobDispatcher(driver);

        Job constraintReminderJob = firebaseJobDispatcher.newJobBuilder()
                .setService(ReminderService.class)
                .setTag(REMINDER_JOB_TAG)
                .setConstraints(Constraint.DEVICE_CHARGING)
                .setLifetime(Lifetime.FOREVER)
                .setRecurring(true)
                .setTrigger(Trigger.executionWindow(
                        REMINDER_INTERVAL_SECONDS,
                        REMINDER_INTERVAL_SECONDS + SYNC_FLEXTIME_SECONDS
                ))
                .setReplaceCurrent(true)
                .build();

        firebaseJobDispatcher.schedule(constraintReminderJob);
