问题
Approaching to the final stage of the authentification, but something is going wrong in handleSignInResult method. It returns Exception code 10 (Developer error) in logs. Google provides comprehensive description:
The application is misconfigured. This error is not recoverable and will be treated as fatal. The developer is an idiot...
What should I do to handle this (get an account) and finally retrive values from account?
Thank you in advance for your help!!!

This error might happen if you are not using same project at console.developers.google and console.firebase.google.com. If project is same at both console make sure you have add your SHA1 Key properly. Get SHA1 from Android studio.
- Open Android Studio
- Open your Project
- Click on Gradle (From Right Side Panel, you will see Gradle Bar)
- Click on Refresh (Click on Refresh from Gradle Bar, you will see List Gradle scripts of your Project)
- Click on Your Project (Your Project Name form List (root))
- Click on Tasks
- Click on Android
- Double Click on signingReport (You will get SHA1 and MD5 in Run Bar(Sometimes it will be in Gradle Console))
- Select app module from module selection dropdown to run or debug your application You also need to get google-services.json from firebase console and put into your project.

I would like to add Supplemental Information as to Why @Patrick R answer (above works/marked as correct). To execute your project/practice, Google Console needs to ID your app via SHA-1 key when its distributed on Google Play Market, However, when your are simply experimenting with Login confirmation and Proof Of Concept, then it associates the debug SHA-1 key (your app automatically generates this) for this exact purpose, keeping your testing and production changes modular.

I landed into the same problem and wasted hours. On digging deeper into OAuth and OpenId, I figured out the reason. We are doing a conceptual error here.
For android or any other platform (except web), you need to create at least two types of client id in the same project of google API console. These Client ID types are:
- Web Application
- Android
You can create them in any order. While creating Android type Client Id, you need to give package name and SHA1. While creating Web Application Id, you just need to give a name.
You don't need to do anything with any of these id's further until you want to verify the user at your backend. In other words, if you want your backend server to ask google server about this user's information, then only you would need Web Application Id. The conceptual flow is as follows:
- First send Web Application Client Id from Android App to Google Sign-in Server as an additional option using requestIdToken(your_web_app_client_id).
- You will get back a token in Android app upon user's sign in.
- Send this token to your backend.
- Now your backend can exchange this token with Google Servers to get user's information
Send this Web Appplication Client Id from Android App to backend server.
Use this Web Application Id if you want to verify user at your backend.
