Answer 1

Add SHA1 key value to the google-services.json file. For that open the google-services.json file in any text editor and add

"certificate_hash": "5e8f16062ea3cd2c4a0d547876baa6f38cabf625"

with your hash value without a colon (:) in android_client_info

Demo google-services.json file

{
  "project_info": {
    "project_number": "108005055433",
    "firebase_url": "https://se-ai-camera.firebaseio.com",
    "project_id": "demo-app",
    "storage_bucket": "demo-app.appspot.com"
  },
  "client": [
    {
      "client_info": {
        "mobilesdk_app_id": "1:108005055433:android:323bf88853cd2899872618",
        "android_client_info": {
          "package_name": "com.myapp",
          "certificate_hash": "5e8f16062ea3cd2c4a0d547876baa6f38cabf625"
        }
      },
      "oauth_client": [
        {
          "client_id": "108005055433-q748qmcrn9a3j4qmg9srrkbotvr4emh1.apps.googleusercontent.com",
          "client_type": 3
        }
      ],
      "api_key": [
        {
          "current_key": "AIzaSyAuGCMQoW0tM7QMhpAgMIi0sK3vj0Nj8lk"
        }
      ],
      "services": {
        "appinvite_service": {
          "other_platform_oauth_client": [
            {
              "client_id": "108005055433-q748qmcrn9a3j4qmg9srrkbotvr4emh1.apps.googleusercontent.com",
              "client_type": 3
            }
          ]
        }
      }
    }
  ],
  "configuration_version": "1"
}

or add SHA1 key in the (firebase console) app settings and download the updated google-services.json file.

Then change the GoogleSignIn.configure() method parameter as empty. This is the most important step.

Answer 2

For those who are still looking for solutions:

1. Please match your key fingerprint in firebase console.

2. Do not initialize the configuration with keys, I repeat, do not provide any configuration object in the .configure() function Do this GoogleSignIn.configure().

3. Point 2 will resolve the issue. :)
