Firebase google-services.json with multiple projects?

Question

For our app I am using two different firebase projects:

• Live: Contains the live iOS & Android app
• Test: Contains all our iOS & Android testing apps

As far as I could see the google-services.json (Android) contains the firebase project information and all related apps (as "client"). Is it supported to add a second "project_info" into this file?

Why don't you try android application flavors, for that Google just included support for flavors on version 2.0 of the play services plugin. Since this version of the gradle plugin com.google.gms:google-services:2.0.0-alpha3

you can do this

app/src/ flavor1/google-services.json flavor2/google-services.json Version 3.0.0 of the plugin will search for the json file in these locations (considering you have a flavor flavor1 and a build type debug):

/app/src/flavor1/google-services.json
/app/src/flavor1/debug/google-services.json
/app/src/debug/google-services.json
/app/src/debug/flavor1/google-services.json
/app/google-services.json

This worked for me even using flavorDimensions. I have free & paid in one dimension and Mock & Prod in the other dimension. I also have 3 buildTypes: debug, release and staging.

How many google-services.json files will depend on your project's characteristics, but you will need at least one json file for every Google project.
