当活动处于后台时，Firebase通知不起作用 [英] Firebase notification is not working when activity is in background or not

问题描述

我有与Firebase示例代码提供的相同的代码。当活动处于前台状态或打开状态时，它工作正常。但是，当活动被关闭或在后台状态，那么它不能正常工作。问题就是这样...

1. 应用程序图标不显示应用程序。

$ b

2. 默认情况下将应用程序名称作为通知的标题

当应用程序处于后台状态或未在设备上打开时间通知，则LogCat显示以下详细信息：

  09-16 15：55：56.056 12113 -12113 / com.testdemofb D / FirebaseApp：com.google.firebase.auth.FirebaseAuth未链接。跳过初始化。 
 09-16 15：55：56.089 12113-12113 / com.testdemofb D / FirebaseApp：com.google.firebase.crash.FirebaseCrash未链接。跳过初始化。 
 09-16 15：55：56.176 12113-12113 / com.testdemofb I / FA：应用测量正在启动，版本：9452 
 09-16 15：55：56.177 12113-12113 / com。 testdemofb I / FA：启用调试日志记录运行：adb shell setprop log.tag.FA VERBOSE 
 09-16 15：55：56.286 12113-12113 / com.testdemofb I / FirebaseInitProvider：FirebaseApp初始化成功
 09-16 15：55：56.518 12113-12147 / com.testdemofb I / FA：找不到代码管理器，因此不会使用
  

如果有任何解决方案，那么帮助我

谢谢...

解决方案
 FCM使用两种类型的消息，即。通知和数据。详细了解此处。我想你正在发送一个通知。你需要发送一个数据信息。
 
 
 
类似这样的。 
 
 
  {
to：bk3RNwTe3H0：CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1 ...，
data：{
Nick：Mario，
body：great匹配！，
房间：PortugalVSDenmark
}，
} 
  
 
I have same coding as provided by firebase sample code. It works fine when activity is in foreground state or opened. But when activity is closed or in background state then it does not work properly. Problem is like that...

App icon is not shown of application.
By default take app name as a title of notification
And when app is in background state or not opened on device that time notification occurs then LogCat shows following details :
09-16 15:55:56.056 12113-12113/com.testdemofb D/FirebaseApp: com.google.firebase.auth.FirebaseAuth is not linked. Skipping initialization.
09-16 15:55:56.089 12113-12113/com.testdemofb D/FirebaseApp: com.google.firebase.crash.FirebaseCrash is not linked. Skipping initialization.

09-16 15:55:56.518 12113-12147/com.testdemofb I/FA: Tag Manager is not found and thus will not be used
if any solution for that then help me


Thanks...

        </intent-filter>
    </service>

解决方案
There are two types of messages that FCM uses, viz. notification and data. Read more about it here. I think you are sending a notification. You need to send a data message.

Something like this.
{
"to" : "bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1...",
   "data" : {
 "Nick" : "Mario",
 "body" : "great match!",
 "Room" : "PortugalVSDenmark"
},
}
