Android O中的通知徽章

我使用谷歌Nexus 5x与Android Oreo SDK进行测试.我无法在主屏幕中找到应用程序中的通知徽标图标,即使我从应用程序获得通知并且应用程序快捷方式未显示数字.以下是片段:

 final NotificationManager mNotific=(NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);

            CharSequence name="Ragav";
            String desc="this is notific";
            int imp=NotificationManager.IMPORTANCE_HIGH;
            final String ChannelID="my_channel_01";

            NotificationChannel mChannel=new NotificationChannel(ChannelID,name,imp);
            mChannel.setDescription(desc);
            mChannel.setLightColor(Color.CYAN);
            mChannel.canShowBadge();
            mChannel.setShowBadge(true);

            mNotific.createNotificationChannel(mChannel);

            final int ncode=1;

            String Body="This is testing notific";
            final Notification n= new Notification.Builder(getApplicationContext(),ChannelID)
                    .setContentTitle(getPackageName())
                    .setContentText(Body)
                    .setNumber(5)
                    .setBadgeIconType(R.mipmap.ic_launcher_round)
                    .setSmallIcon(R.mipmap.ic_launcher_round)
                    .setAutoCancel(true).build();

            for(int i=0;i<25;i++) {
                Thread.sleep(1000);
                mNotific.notify(ncode, n);
            }
