Just implement the new GCM. For official document,

Copy the google-services.json file you just downloaded into the app/ or mobile/ directory of your

Answer 1

I have just answered a similar question here for different productFlavors.

In your case it's debug/production. I don't know why you need to switch between production and debug but i think you can do the same as what I proposed for flavors.

Create two extra folders src/release and src/debug , in each of the folders you put the corresponding google-services.json , so you will have: src/release/google-services.json and src/debug/google-services.json

Now in gradle add this :

android {

// set build config here to get the right gcm configuration.
//def myBuildConfig = "release"
def myBuildConfig = "debug"

// this will copy the right google-services.json file to app/ directory.
if (myBuildConfig.equals("release")) {
    println "--> release copy!"
    copy {
        from 'src/release/'
        include '*.json'
        into '.'
    }
} else {
    println "--> debug copy!"
    copy {
        from 'src/debug/'
        include '*.json'
        into '.'
    }
}

// other stuff
}

Base on my test switching build type or flavor, I noted that we should differentiate them as following:

For Debugging:
src/flavorDebug/google-services.json
src/flavor/debug/google-services.json
src/debug/flavor/google-services.json
If all flavors use only one firebase project with different app ids:
src/debug/google-services.json

For Releasing:
src/flavorRelease/google-services.json
src/flavor/release/google-services.json
src/release/flavor/google-services.json
If all flavors use only one firebase project with different app ids:
src/release/google-services.json

Without flavor should be as the following:
src/debug/google-services.json
src/release/google-services.json

With flavor but not separate build type:
src/flavor/google-services.json

For overall flavors and build types:
src/google-services.json

Note: flavor is referred to your flavor's name.
