Can't set Build Action to GoogleServiceJson

问题

I'm working with Xamarin-Android to make an application, so I need to set Build Action to my google-services.json file but there is no such Property as GoogleServicesJson, and when I try just to write it, it shows me an exception:

Exception of type 'System.Runtime.InteropServices.ExternalException' was thrown.

I tried to save and then restart Visual Studio, but it didn't solve the problem.

If you know how to solve this problem, please help me! :)
That's the file I'm clicking on

回答1:

The GoogleServicesJson build type comes from the Xamarin.GooglePlayServices.Basement.targets.

If your project does not have Xamarin.GooglePlayServices.Basement installed via one of its dependents, usually Xamarin.GooglePlayServices.Gcm or Xamarin.Firebase.Messaging if we are talking about messaging, then you will not have that build action available.

After adding a package that installs Basement, or manually adding it yourself, your .csproj will contain an import for Xamarin.GooglePlayServices.Basement.targets and GoogleServicesJson will be available as a build type:

.csproj import example:

  <Import Project="..\packages\Xamarin.GooglePlayServices.Basement.42.1001.0\build\MonoAndroid70\Xamarin.GooglePlayServices.Basement.targets" Condition="Exists('..\packages\Xamarin.GooglePlayServices.Basement.42.1001.0\build\MonoAndroid70\Xamarin.GooglePlayServices.Basement.targets')" />

Even after installing "Xamarin.GooglePlayServices.Basement" GoogleServiceJson option was not showing. Surprisingly but when i quit Xamarin studio and opened it again it starts displaying.

1-Download first these Packages:

Xamarin.Firebase.Common

Xamarin.Firebase.Config

Xamarin.Firebase.Iid

Xamarin.GooglePlayServices.Base

Xamarin.GooglePlayServices.Basement

Xamarin.GooglePlayServices.Tasks

2-then restart and rebuild 3-from google-services.json --> Properties --> build Action: GoogleServicesJson

回答4:

In Visual Studio close the Project and reopen it. That worked for me:)

回答5:

Download first these Packages:

then restart

回答6:

GoogleServiceJsom is coming from Xamarin.GooglePlayServices.Basement package. If it is not visible after the package installation restart your visual studio project, it will work

回答7:

I thougt i was doing it wrong but you dont get the Build action by rightklick it like a example from Mac

PS You dont right klick on the Google-Services.json and see the Build avtion You press properties and then at the properties you find the Build action

回答8:

While using AppCenter, I was not adding App centre and App Center Push packages to Android Dependencies folder. Upon adding GoogleServicesJson immediately showed up

回答9:

I was getting stuck with this because the Microsoft guide https://docs.microsoft.com/en-us/xamarin/android/data-cloud/google-messaging/remote-notifications-with-fcm?tabs=windows which was saying to install Xamarin.GooglePlayServices.Base directly.

What worked: install Xamarin.GooglePlayServices.Gcm through Nuget
