我调用sendToToken（“令牌”）与我的设备的有效令牌，它不工作，我不知道我错过了什么是没有失败，我调试发送正确，但通知只是dosnt出现在目标设备上，有我的应用程序安装。
我错过了什么，有人能帮我弄清楚吗？我和我的搭档已经为此挣扎了几个星期了
MyFirebaseMessagingService.java

                .setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION))
                .setAutoCancel(true);

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

        notificationManager.notify(0, notificationBuilder.build());
    }
}

tl;dr：没有办法通过FCM直接从一个设备发送消息到另一个设备。您需要从受信任的环境中调用FCM来发送消息 * 到 * 设备。
您调用的send方法记录为：
向上游发送message到应用服务器。
您将需要从architectural overview查看此图，以了解其含义：

当您调用send时，客户端会向FCM发送一条消息，FCM会将其传递到您配置的应用服务器。它不会不将消息传递到其他设备。
要向设备发送消息**，您需要阅读building send requests on your app server上的文档。其中有针对各种平台使用Firebase Admin SDK或调用REST API的示例。需要认识到的最重要的一点是，此类调用必须始终来自受信任的环境/应用服务器，例如您的开发机器、您控制的服务器、或者类似于Cloud Functions/Cloud Run。
