FAQ / Troubleshooting

Android​

Login does not work when downloading from the Play Store.​

See the next paragraph.

DEVELOPER_ERROR or code: 10 or Developer console is not set up correctly error message​

This is always (!always!) a configuration mismatch between your app and the server-side setup (in Firebase or Google Cloud console).

Follow these pointers:

  • Follow the setup guide and perform its steps once again.
  • Make sure that your SHA-1 (NOT SHA-256!) certificate fingerprints and Android package name you entered in Firebase Console / Google Cloud Console are correct.
  • Add the SHA-1 from the output of this command to your Firebase / Google Cloud Console. You should be able to recognize the SHA-1 — do not add a hash if you're not sure of its origin.
  • Search the issue tracker for old reports of the error.
  • If you're passing webClientId in the configuration object to GoogleSignin.configure(), make sure it's correct and that it is of type web (NOT Android!). You can get your webClientId from Google Developer Console. It is listed under "OAuth 2.0 client IDs".
  • If you are using Firebase, you need to add Google as a Sign-in method in Firebase itself (Build -> Authentication -> Sign-in method). If you have already created an app, you will be prompted for fingerprints and then you will get a new google-services.json which you need to use in your app instead of the old one.

Login does not work when using Internal App Sharing.​

If you get a DEVELOPER_ERROR when using Internal App Sharing, it is because Google resigns your application with its own key.

See the previous paragraph.

"A non-recoverable sign in failure occurred"​

See this comment. Or this SO question.

Changing play-services-auth version​

See "Choose Dependency versions" above.

Package name !== application id​

When adding a new oauth client, google asks you to add your package name. In some cases your package name is not equal to your application id. Check if your package name in the AndroidManifest.xml is the same as your application/bundle id. Find your application id in the play console or android/app/build.gradle. The format looks like com.yourapp.id.

iOS​

On iOS the app crashes when tapping Sign In button​

Along with "Your app is missing support for the following URL schemes" error in console.

Your Url Schemes configuration is incorrect.

If you use Expo, make sure that the config plugin is configured correctly.

In vanilla React Native projects, add URL type like this.
