Rich Push Notification不会隐藏扩展包含图像的通知时的大图标

Question

我正在跟随android开发人员文档创建一个包含一个图像的可扩展通知。我已经按照docs编写了相同的代码，但是在我扩展通知后我的大图标没有隐藏。 这是我的代码：-

NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this, id)
                            .setSmallIcon(getNotificationIcon())
                            .setColor(ContextCompat.getColor(this, R.color.colorPrimary))
                            .setContentTitle(title)
                            .setContentText(data.get("message"))
                            .setLargeIcon(bitmap)
                            .setStyle(new NotificationCompat.BigPictureStyle().bigPicture(bitmap)
                                    .bigLargeIcon(null))
                            .setAutoCancel(true).setChannelId(id)
                            .setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION));   

Notification notification = notificationBuilder.build();
        notification.sound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

        notification.flags |=
        Notification.FLAG_AUTO_CANCEL; //Do not clear  the notification
            notification.defaults |= Notification.DEFAULT_LIGHTS; // LED
            notification.defaults |= Notification.DEFAULT_VIBRATE;//Vibration

        notificationManager.notify(mUniqueId, notification);

和android开发人员的代码：-

Notification notification = new NotificationCompat.Builder(mContext, CHANNEL_ID)
    .setSmallIcon(R.drawable.new_post)
    .setContentTitle(imageTitle)
    .setContentText(imageDescription)
    .setLargeIcon(myBitmap)
    .setStyle(new NotificationCompat.BigPictureStyle()
            .bigPicture(myBitmap)
            .bigLargeIcon(null))
    .build();

我无法理解我是否缺少某些东西或做错了什么。请帮忙 。预先谢谢你。

我得到了答案！ 实际上，这是特定于设备的问题。某些android设备并未在扩展通知时隐藏大图标，而有些设备则将其隐藏。
