google-services.json for different productFlavors

The Solution to google-services.json for different productFlavors is


Google included support for flavors in 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

Step 1: add to gradle

// To auto-generate google map api key of google-services.json
implementation 'com.google.android.gms:play-services-maps:17.0.0'

Step 2: add to AndroidManifest.xml in application tag

<meta-data
    android:name="com.google.android.geo.API_KEY"
    android:value="@string/google_api_key" />

Step 3: download each flavor JSON file from firebase and add it

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

Version 3.0.0 of the plugin searches for the json file in these locations (considering you have a flavor flavor1 and a build type debug):

/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. This is how it looks in my project for the FreeProd flavor:

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.
