How to integrate two or more google-services.json file together for different google service in same project using Android Studio

Question

I am making a project where I want to integrate GCM and Google sign in but the problem is both have google-services.json configuration file which we need to add in our project.

So, how can I integrate both google-services.json configuration file in my project.

Here is my one of the configuration file

{
  "project_info": {
    "project_id": "default-xxx",
    "project_number": "xxx",
    "name": "xxx"
  },
  "client": [
    {
      "client_info": {
        "mobilesdk_app_id": "1:xxx",
        "client_id": "x.package",
        "client_type": 1,
        "android_client_info": {
          "package_name": "x.package_name"
        }
      },
      "oauth_client": [],
      "api_key": [],
      "services": {
        "analytics_service": {
          "status": 1
        },
        "cloud_messaging_service": {
          "status": 1,
          "apns_config": []
        },
        "appinvite_service": {
          "status": 1,
          "other_platform_oauth_client": []
        },
        "google_signin_service": {
          "status": 1
        },
        "ads_service": {
          "status": 1
        }
      }
    }
  ],
  "client_info": [],
  "ARTIFACT_VERSION": "1"
}

Answer 1

Finally I have done it as follows:

Step1: Open your desired google service page in my case its google sign in and GCM. There will be a button saying Get configuration file, click on that and input your details and get the configuration files.

Step2: Check both of the configuration file it would have same configuration in project_info object and client_info object. The difference would be in services object where you have to check for status if you have added two or more service the status value would be 2 which means they are enabled services. You can see in below configuration file which I have generated for two of the services which is Google sign in and GCM.

You just have to check your status values in services object where it is saying 2 for all the services you have integrated in your project is the configuration file you have to add.

{
  "project_info": {
    "project_id": "xxxxxxxxxx",
    "project_number": "xxxxxxxx",
    "name": "xxxxxxxxxxx"
  },
  "client": [
    {
      "client_info": {
        "mobilesdk_app_id": "xxxxxxxxxxx",
        "client_id": "xxxxxxxxxxx",
        "client_type": 1,
        "android_client_info": {
          "package_name": "xxxxxxxxxx"
        }
      },
      "oauth_client": [
        {
          "client_id": "xxxxxxxxxx",
          "client_type": 1,
          "android_info": {
            "package_name": "xxxxxxxx",
            "certificate_hash": "xxxxxxxxxxx"
          }
        }
      ],
      "api_key": [],
      "services": {
        "analytics_service": {
          "status": 1
        },
        "cloud_messaging_service": {
          "status": 2, <======= this is my gcm service status
          "apns_config": []
        },
        "appinvite_service": {
          "status": 1,
          "other_platform_oauth_client": []
        },
        "google_signin_service": {
          "status": 2   <===== this my google sign in service status
        },
        "ads_service": {
          "status": 1
        }
      }
    }
  ],
  "client_info": [],
  "ARTIFACT_VERSION": "1"
}

Note: I am using Google sign in service so its generating oauth_client field value also which you wouldn't get if you generate only for GCM.
