android - Firebase 不从控制台发送通知

Question

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.链接的图像显示了我在发送通知时从控制台看到的内容(完成状态、与我发送通知的时间相对应的交付日期，但实际上没有发送任何内容)。

我最初是在我自己的应用程序中发现这个问题，但后来又用 Firebase's demonstration app 测试了这个问题，但无济于事。我可以毫无问题地获取 FCM 注册 token ，因此可以连接到 Firebase。我主要在使用 API 25 的 Android Studio 模拟器上进行测试，但我也在使用 API 17 和 23 的模拟器以及使用 API 17 和 23 的个人安卓设备上进行了测试。我尝试了各种 Firebase/Google播放从 9.0.2 到当前 10.0.1 的版本。我也没有更改 Firebase 演示应用程序中的任何代码(除了 build.gradle 中的依赖项和试图解决我的问题的 list )。

让这个问题更加奇怪的是，这些通知最终会发送，但它花费的时间异常长，而且总是在应用程序/模拟器关闭之后，所以我从未真正看到过它们。有时需要几个小时，但通常直到第二天我查看控制台并看到它已发送。最初我将此归因于一个简单的延迟，但在过去一周半的时间里我发送了 50 多条测试通知，所有通知都遇到了这个问题。

这是我所做的任何更改的唯一文件当前的样子(最近的测试通知已发送到具有 API 25 的模拟器):

我应该补充一点，永远不会触发 onMessageReceived。

Answer 1

在 build.gradle 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' 

在你根的 build.gradle 中添加以下内容

classpath 'com.google.gms:google-services:3.0.0' 

您生成的 google-services.json 提供您的包名称和 sha1 key ，您应该能够接收从 firebase 发送的推送通知。再次检查您是否复制了正确的 sha1 key ，而不是 sha256 或 mda5 key
