Why is my program returning the google sign in 12500 error?

问题

I am trying to get google sign in to work with my app. So far I think I have done everything correctly. I followed the google documentation on setting up the googlesigninclient, and can get the app to get to the sign in button, but when someone tries to sign in it returns the 12500 error (SIGN_IN_FAILED). I have the google api credentials set up correctly, and have it set up correctly in my debug.keystore, and I have the credentials.json file downloaded and in my app folder. I will post my code, does anyone know why it isn't working?

Thanks!

P.S. Just to head people off at the pass, I was testing it on my phone which definately has the latest version of google play services, so I don't think that is the problem

For me it was because I enabled Google Play App Signing, so you have to get the SHA1 from Release management -> App signing -> "App signing certificate" section

回答2:

Error code 10 is DEVELOPER_ERROR: https://developers.google.com/android/reference/com/google/android/gms/common/api/CommonStatusCodes.html#DEVELOPER_ERROR

This almost certainly means you have not properly registered your SHA1 and Package Name in the Google API console: https://developers.google.com/identity/sign-in/android/start

If you are 100% sure that you have done this correctly, make sure that your GoogleSignInOptions are correct. In particular, make sure the web client ID (if you're using it) belongs to the same project where you registered your package name and SHA1.

Simply update your Google Play Services to the latest version . If you are using AVD, Nexus 5 and 5X images support Google Play. Once the emulator is up and running, go to the Extended Controls Menu > Google Play then update.

It may be a late answer, but helpful for some one. Enable Firebase for your project. Follow the steps to setup an android app. Make sure you have given support email. In my case that was the problem and giving a valid email, fix the problem.
