First, place the respective google_services.json for each buildType in the following locations:

app/src/debug/google_services.json
app/src/test/google_services.json
app/google_services.json

Note: Root app/google_services.json This file should be there according to the build variants copy the json code in the root json file

Now, let’s whip up some gradle tasks in your: app’s build.gradle to automate moving the appropriate google_services.json to app/google_services.json

copy this in the app/Gradle file

task switchToDebug(type: Copy) {
    description = 'Switches to DEBUG google-services.json'
    from "src/debug"
    include "google-services.json"
    into "."
}

task switchToRelease(type: Copy) {
    description = 'Switches to RELEASE google-services.json'
    from "src/release"
    include "google-services.json"
    into "."
}

Great — but having to manually run these tasks before you build your app is cumbersome. We would want the appropriate copy task above run sometime before: assembleDebug or :assembleRelease is run. Let’s see what happens when :assembleRelease is run: copy this one in the /gradlew file

Zaks-MBP:my_awesome_application zak$ ./gradlew assembleRelease
Parallel execution is an incubating feature.
.... (other tasks)
:app:processReleaseGoogleServices
....
:app:assembleRelease

Notice the :app:processReleaseGoogleServices task. This task is responsible for processing the root google_services.json file. We want the correct google_services.json to be processed, so we must run our copy task immediately beforehand. Add this to your build.gradle. Note the afterEvaluate enclosing.

copy this in the app/Gradle file

afterEvaluate {
    processDebugGoogleServices.dependsOn switchToDebug
    processReleaseGoogleServices.dependsOn switchToRelease
}

Now, anytime :app:processReleaseGoogleServices is called, our newly defined :app:switchToRelease will be called beforehand. Same logic for the debug buildType. You can run :app:assembleRelease and the release version google_services.json will be automatically copied to your app module’s root folder.

Answer 2

The current plugin (com.google.gms:google-services:2.1.X) supports flavors but not types.

So if you create a productflavor you can put the json file in src/$flavorname

Example:

app/src/
    flavor1/google-services.json
    flavor2/google-services.json

Currently it doesn't work with types (debug, release...) but you can use somenthing like this:

app/src/release/google-services.json
app/google-services.json

In this case the plugin looks in the locations and stops when it finds a google-services.json file.

If you are using a flavor it becomes:

app/src/foo/release/google-services.json
app/src/foo/google-services.json

You can find updated info here.

What about the latest plugin? Does it support types? – Maebashi

I'm currently using the following versions: com.google.gms:google-services:4.3.3, com.google.firebase:firebase-messaging:20.2.0

Place your google-services.json file in your $projectName/app/src/$buildType directory. For example, place one json file in src/release and another in src/debug. You will likely need to create the release & debug folders.

Note: It's a common mistake to add these files in the app folder, be sure you add this in the src folder as described above.

The google-services plugin always looks for the google-services.json file in two directories: First, on the $projectName/app/src/$buildType/google-services.json. If it does not find it here, it goes one level above, to the $projectName/app/google-services.json. So, when you are building the debug version of your app, it will search for the google-services.json on the $projectName/app/src/debug/ directory.

I have only src/debug folder which holds for the debug build. Another for production app which is contained in src/google_services.json. Both the files have array of "client_info" object for both com.myapp.debug and com.myapp. Is that correct ? – Cite

That may or may not work but my answer says to put your production google services in the src/release folder, not the src folder. That's how i did mine. – Antichrist
