Question

环境：

compileSdkVersion 26
buildToolsVersion "28.0.0"

compile 'com.google.android.gms:play-services-ads:11.4.0'
compile 'com.google.android.gms:play-services-gcm:11.4.0'
compile 'com.google.firebase:firebase-messaging:11.4.0'

**说明：**

我正在从批处理程序发送FCM通知，并且直到7.0版，一切都工作正常。现在，我更改了Android Oreo（使用的频道等）的代码，这是测试结果：

直到7.0版：

 Notification received when App is open? Yes

 Notification received when App is in the background? Yes

 Notification received when App is Closed? Yes

版本8.1（Oreo）：

 Notification received when App is open? Yes

 Notification received when App is in background? Yes

 **Notification received when App is Closed? No**

代码

String channelId =  "abc";
        AudioAttributes audioAttr = new AudioAttributes.Builder()
                .setUsage(AudioAttributes.USAGE_NOTIFICATION)
                .setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)
                .build();
        NotificationChannel channel = new NotificationChannel(channelId, "abc", NotificationManager.IMPORTANCE_HIGH);
        channel.setDescription("description");
        channel.enableLights(true);
        channel.setShowBadge(true);
        channel.enableVibration(true);
        channel.setSound(Uri.parse("android.resource://" + getPackageName() + "/" + R.raw.s), audioAttr);
        notificationManager.createNotificationChannel(channel);

        Notification.Builder mBuilder = new Notification.Builder(getApplicationContext(), channelId)
                .setSmallIcon(R.drawable.bell)
                .setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.cc))
                .setContentTitle(title)
                .setContentText(content)
                .setAutoCancel(true)
                .setContentIntent(pendingIntent)
                .setOngoing(true);

        int notificationId = 1;
        notificationManager.notify(notificationId, mBuilder.build());

问题：

为什么我在关闭应用程序后没有收到通知？
为什么通知徽章不显示？

Oreo-在应用关闭时未收到通知，但在后台运行正常
