Can't sign in with Google

[fabyeah]

Email sign in works, but when I try to sign in with Google, I'm getting a toast "Code: 10, Message: 10:" and nothing happens.

Google Sign in from the web app (using firebaseui-react) works, so the Firebase/Google setup should be correct.

Hi @fabyeah, the issue is with android or iOS?

[fabyeah]

@oijusti I tested it with android device

[fabyeah]

It works on iOS.

To make it work on android, it seems like one has to add "SHA certificate fingerprints" to the Android App in the Firebase console project settings.

Kind of cumbersome if you just want to play around and test an app locally without uploading it to Google Play... 🙁

Good catch!

Just for posterity: I actually had the wrong SHA1 set in Firebase. So if you encounter this error, make sure you get the SHA1 from the debug.keystore in your project's android/app folder, NOT from some rogue debug.keystore for example in /Users/<username>/.android/debug.keystore. You can use keytool -keystore debug.keystore -list -v in the project's android/app folder to get the SHA1.

So for development you probably only need that one SHA1 (haven't tried it).
