问题描述

默认FirebaseApp在此过程中未初始化.确保首先调用FirebaseApp.initializeApp(Context).

Default FirebaseApp is not initialized in this process. Make sure to call FirebaseApp.initializeApp(Context) first.

我尝试了很多事情，但无法在设备中获取通知.

i have tried with many things but i am not able to Get notifications in devices.

我也尝试了以下方法.

在属性"窗格中，设置构建操作"，然后在解决方案资源管理器"窗口中选择google-services.json.

In the Properties pane, set the Build Action Select google-services.json in the Solution Explorer window.

在属性"窗格中，将生成操作"设置为GoogleServicesJson(如果未显示GoogleServicesJson生成操作，请保存并关闭解决方案，然后重新打开它):至GoogleServicesJson

In the Properties pane, set the Build Action to GoogleServicesJson (if the GoogleServicesJson build action is not shown, save and close the Solution, then reopen it):to GoogleServicesJson

之前，通知是有效的，但是在我将xamarin表单更新为2.5.0.280555和Xamarin.Firebase.Messaging.42.1021.1之后，它停止了工作.

Notification was working before, but after I update the xamarin forms to 2.5.0.280555 and Xamarin.Firebase.Messaging.42.1021.1, it stopped working .

推荐答案

请确保:

1. AndroidManifest.xml中的软件包名称与google-services.json
中的软件包名称相同
2. google-services.json构建操作设置为GoogleServicesJson
3. 第2步后，重新启动您的IDE&清洁重建
4. 在LoadApplication(..)
之前在MainActivity.OnCreate中明确调用FirebaseApp.InitializeApp(Application.Context);

1. Package name in AndroidManifest.xml is identical to one in the google-services.json
2. google-services.json build action is set to GoogleServicesJson
3. After step 2 restart your IDE & clean & rebuild
4. Explicitly call FirebaseApp.InitializeApp(Application.Context); in MainActivity.OnCreate just before the LoadApplication(..)
