Summarize the problem

I want to/already have integrate/integrated the Google-Login as described by Google here. It works... at least I thought so. After publishing the app in the Play store I got feedback that the login via google isn't working on devices that have Android 10 installed --> only on Android 10, weird

In Android Studio I get the following message/error when trying it with Android 10:

Exception com.google.android.gms.common.api.ApiException: 12500:

Describe what you have tried

I have tried multiple things:

  • Everything is up-to-date
  • targetSdkVersion set to Android 10, sane thing for compileSdkVersion
  • Literally anthing mentioned here (Support mail set; Fingerprint is corret, ... as said before, it works on e.g. Android 9 devices)

Info: I am not using firebase. This is my first post here, hopefully I didn't mess up my question. Thanks for your help!

This worked for me... in the beginning. I just found out that changing the SHA1 back to the release key that I have locally --> it worked.

I have no idea why it worked in the first place and after some time it stopped.

If you have the same problem:

  • Double check SHA1 key set in Google/Firebase
  • I found out that OAuth-Screen that could also cause this problem --> be aware of that
