这个问题已经解决了。请参阅下面我的解决方案。

我刚把我的短信应用程序转换成FCM。你可以看到我经历的过程 here . 既然完成了,我的通知就不起作用了。如果我的FirebaseMessagingService收到一条消息,而主应用程序不活动,我会在正在运行的手机上创建一个通知。

这是从FirebaseMessagingService调用的代码。这个代码已经运行了好几年了。

public static void raiseNotification( String username, String mesText, int count)
{
    String message = "From: " + username + " " + mesText;
    if (count > 1)
    {
        count--;
        message = message +  " + " + count + " more";
    }



    NotificationCompat.Builder b = new NotificationCompat.Builder(GlobalStuff.GCT);

    Intent intent = new Intent(GlobalStuff.GCT, MainActivity.class);
    intent.putExtra("whattodo", username);
    intent.setAction(Long.toString(System.currentTimeMillis())); //just to make it unique from the next one
    PendingIntent pIntent = PendingIntent.getActivity(GlobalStuff.GCT, 0, intent, PendingIntent.FLAG_CANCEL_CURRENT);


    b.setContentTitle("New SafeTalk Message")
            .setSmallIcon(R.drawable.ticon)
            .setContentText(message)
            .setTicker("New SafeTalk Message")
            .setContentIntent(pIntent)
            .setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION))
            .setAutoCancel(true);
    //.addAction(R.drawable.smallredball, "Read Now", pIntent)
    //.addAction(R.drawable.smallquestion, "hello there", pIntent);

    NotificationManager mgr = (NotificationManager)GlobalStuff.GCT.getSystemService(NOTIFICATION_SERVICE);
    mgr.notify(0, b.build());
}

这个问题解决了。一旦你为Android编写了一个应用程序,Google会让你在余生中全职工作,只是为了让它继续工作。 他们正在打破变革的恶魔

实际上,这个代码在Oreo中并不完全有效。下一篇关于我的通知的帖子

   private void sendNotification(String messageBody) {
        Intent intent = new Intent(this, MainActivity.class);
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
                PendingIntent.FLAG_ONE_SHOT);

        String channelId = getString(R.string.default_notification_channel_id);
        Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        NotificationCompat.Builder notificationBuilder =
                new NotificationCompat.Builder(this, channelId)
                .setSmallIcon(R.drawable.ic_stat_ic_notification)
                .setContentTitle("FCM Message")
                .setContentText(messageBody)
                .setAutoCancel(true)
                .setSound(defaultSoundUri)
                .setContentIntent(pendingIntent);

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

        // Since android Oreo notification channel is needed.
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            NotificationChannel channel = new NotificationChannel(channelId,
                    "Channel human readable title",
                    NotificationManager.IMPORTANCE_DEFAULT);
            notificationManager.createNotificationChannel(channel);
        }

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