Android 应用程序未运行时推送通知未发送到我的手机？

我的应用程序未运行时，推送通知无法显示。问题出在我的华为P9手机上，但在模拟器中一切正常。当应用程序正在运行，并且我已签入应用程序>MyApp>通知并启用推送通知时，将显示通知。为什么呢

我想问题是，不知何故，我需要在某个地方选中一些复选框，以便在应用程序未运行时启用通知。在emulator上一切正常的时候，看到我的手机（和朋友的手机）上发生了这种情况，我想我应该在设置活动中设置一些复选框，以便用户启用推送通知（即使应用程序未运行）？我该怎么做

public class EventNotificationService extends FirebaseMessagingService {
    public static final String TAG = "EventNotifyService";

    public EventNotificationService() {

    }

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        Map<String, String> messageData = remoteMessage.getData();

        if(messageData.containsKey("notification_type")) {
            if (Integer.parseInt(messageData.get("notification_type")) == 1){
                onEventNotification(remoteMessage);
            }

            else if (Integer.parseInt(messageData.get("notification_type")) == 2) {
                onReservationMessage(remoteMessage);
            }
        }
    }

    public void onEventNotification(RemoteMessage remoteMessage) {
        RemoteMessage.Notification notification = remoteMessage.getNotification();
        Map<String, String> event = remoteMessage.getData();

        Intent intent = new Intent(this, EventActivity.class);
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        intent.putExtra(EventActivity.EXTRA_EVENT_URL, "http://clzola.com/api/v1/event/show/public?id=" + Integer.parseInt((String)event.get("id")));

        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent,
                PendingIntent.FLAG_ONE_SHOT);

        Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.ic_stat_ic_notification)
                .setContentTitle(notification.getTitle())
                .setContentText((String) event.get("title"))
                .setAutoCancel(true)
                .setSound(defaultSoundUri)
                .setContentIntent(pendingIntent);

        NotificationManager notificationManager =
                (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

        notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
    }


    private void onReservationMessage(RemoteMessage remoteMessage) {

    }
}

发布您的代码，到目前为止您尝试了什么？我还没有做任何设置活动，但是对于扩展FirebaseMessagesService的my类，它可以很好地工作，就像在模拟器上一样，除了真实的设备之外，相同的应用程序工作起来没有任何缺陷，推送通知不会仅在应用程序未运行时显示@FerdousAhamedPost扩展FireBaseMessages服务的类是否正在发送
