我在从Firebase控制台向Android设备发送推送通知时遇到问题。 Specifically, Firebase is not attempting to send the notification.链接的图像显示我在发送通知时从控制台看到的内容（完成状态，交付日期与我发送的时间相对应，但实际上没有发送）。
我最初在自己的应用程序中发现了这个问题，但继续使用Firebase's demonstration app来测试问题，但无济于事。我可以毫无问题地获取FCM注册令牌，因此与Firebase有连接。我主要在使用API 25的Android Studio中的模拟器上进行测试，但我还在使用API 17和23的模拟器以及使用API 17和23的个人Android设备上进行了测试。我已经尝试过了各种Firebase / Google Play版本，范围从9.0.2到10.0.1。我还没有更改Firebase演示应用程序中的任何代码（除了build.gradle中的依赖项和尝试解决我的问题的清单）。
这个问题更令人陌生的原因是这些通知最终会发送，但这需要花费相当长的时间，并且它总是在app / emulator关闭之后，所以我从未真正看过他们。有时它需要几个小时，但通常直到第二天我才看到控制台并发现它已发送。最初我把这个简单推迟到了一个简单的延迟，但我在过去一周半内发送了50多个测试通知，所有这些都发生了这个问题。
这是我目前所做的任何更改的唯一文件（最新的测试通知已发送到使用API 25的模拟器）：

我应该补充说，onMessageReceived永远不会被触发。

在build.gradle中的依赖项中添加以下内容：
//Used for firebase services
compile 'com.google.firebase:firebase-core:10.0.1'
编辑：
通常在您应用的build.gradle中使用以下内容
//Used for firebase services
compile 'com.google.firebase:firebase-core:10.0.1'
//Used for push notification services
compile 'com.google.firebase:firebase-messaging:10.0.1'
以下在你的root的build.gradle
中classpath 'com.google.gms:google-services:3.0.0'
您生成的google-services.json提供了您的包名称和sha1密钥，您应该能够接收来自firebase发送的推送通知。再次检查是否复制了正确的 sha1 键，而不是 sha256 和 mda5 键

使用IOS设备。
我的问题是我没有在Firebase控制台中上传APNs文件。
转到Firebase控制台：
->设置
->项目设置
->云消息传递
-> iOS应用配置
->上传APN
