Setup Firebase Remote Config

Question

I want to use Remote Config in a application Xamarin.Forms .
I use a blog - Firebase Remote Config in Xamarin Forms

I have a question about the section: Setup Firebase Remote Config .

Quote

We can setup Firebase Remote Config through the Firebase portal https://console.firebase.google.com/project/Your-Firebase-Project/config and it is an easy process because the portal GUI is nice and friendly. To do it, we add a new parameter key and the default value and of course it can be a json (the GUI has a tool to validate the format of the json content). In the example case the key will be Features and the default value a json:

 { "ShowPlayerDetail": false }

In this case, we setup a key called ShowPlayerDetail to show or not the player detail.

Question:

Where is the JSON file referred to in this section?

Note.

I am currently in a project.

Answer 1

You're using an existing Firebase project but there are no apps in your project, please see the Update-4 screenshot.

You could click the iOS or Android icon to add app to your Firebase project, and make sure the Apple bundle ID matches the Bundle identifier in info.plist of your Xamarin.iOS project, the Android package name matches the packagename in AndroidManifest.xml of your Xamarin.Android project. After registering the app, you can download the google-services.json file for Android and the GoogleService-Info.plist file for iOS.
