Xamarin firebase different google-services,json fo

Question

In a xamarin.android project, we have 2 build configuration (Basic and Pro) also different Package Name.

On firebase we have registered two apps basic and pro in same project. So now we have two google-services.json file.

Now Problem is that - How can we handle different google-services.json file on different Build Configuration.

Answer 1

You can conditionally include/exclude items in the .csproj based upon the Build Configuration

Note: You need to manually edit the .csproj, so make a backup

Answer 2

The solution from Andrespengineer is a good idea, but I couldn't find out how he's doing the switching of the build configuration, because you cannot change it at the build event page.

So I just entered it once and moved it from the end of the .csproj file to the end of my property group:

<PropertyGroup Condition="'$(Configuration)|$(Platform)' == 'Release-Prod|AnyCPU'">
    ...
    <PreBuildEvent>COPY /Y "$(ProjectDir)GoogleServices\prod\google-services.json" "$(ProjectDir)google-services.json"</PreBuildEvent>
</PropertyGroup>

Solved: Xamarin firebase different google-services.json for different compilation settings.

After trying @SushiHangover solution, the following exception occurred when doing build, something like this:

Failed to Read or Deserialize GoogleServicesJson file: google-services.json System.IO.FileNotFoundException: Could not find file [your root directory]\google-services.json'.

at

[your packages directory]\Xamarin.GooglePlayServices.Basement.60.1142.1\build\MonoAndroid80\Xamarin.GooglePlayServices.Basement.targets(66,5): error : Failed to Read or Deserialize GoogleServicesJson file: google-services.json.

Solution: Using Pre-Build event command line

1. Create the folder that contains the different google-services.json files at your [ProjectDir].

Example:

[ProjectDir]/GoogleServices >

google-services-development.json
google-services-production.json
google-services-any.json

where [ProjectDir] is your project directory path.

2. Create a fake google-services.json at your [ProjectDir] level.

3. Include that at your project.

4. Go to properties > Build Action> GoogleServicesJson.

5. Create your build configuration. This is what you will use to change the configuration before compiling and executing the project and choosing which GoogleServiceJson will take action with your configuration.

Go to Build> Configuration manager...> Active solution configuration > New...

Set the name of your configuration and click Ok.

6. Select the configuration you just created (Go to Build> Configuration manager...> Active solution configuration and select it, then close) and configure the command to copy the file from your folder GoogleServices to the [ProjectDir] in the pre-compiled event.

Go to Project> [Your project name] properties... > Build > Pre-Build event command line> Edit pre-build

7. Add your command to copy the file specified to your configuration.

Example with production configuration:

Repeat steps from 5 to 7 for each google-service.json you have.

Example command for development configuration:

COPY /Y "$(ProjectDir)GoogleServices\google-services-development.json" "$(ProjectDir)google-services.json"

Example command for production configuration:

COPY /Y "$(ProjectDir)GoogleServices\google-services-production.json" "$(ProjectDir)google-services.json"

Example command for any configuration:

COPY /Y "$(ProjectDir)GoogleServices\google-services-any.json" "$(ProjectDir)google-services.json"

Now you can switch between Build configurations dinamically to execute the json you want.

I had same issue, in MainActivity you can set dynamic values from ApplicationKey and APIKey based on the package name for dynamic package name I have create different Manifest file and added in .csproj

<PropertyGroup Condition="'$(Configuration)|$(Platform)' == 'qaDebug|AnyCPU'">
    <AndroidManifest>Properties\AndroidManifest-qa.xml</AndroidManifest>
