I am trying to integrate Google Sign In into my app. I don't have a back-end server, I am just getting the details of the logged on Google Account to my app.
I first tried it by using
Google Sign In Example
but I got an error (No code changes made except for printing the stacktrace below). I just used the example SignInActivity as I don't have a back-end server.

From what I read, the issue could be caused by SHA1 Generation.
I followed the complete guide but apparently it's not working.
I copied the SHA1 from gradle signingReport

what could be the possible cause of this?
Thanks
P.S. Could this be a possible cause?
Google Play services out of date. Requires 11720000 but found 10932470

Error PlatformException(sign_in_failed, com.google.android.gms.common.api.ApiException: 12500: , null)
This 12500 Error can be solved by adding a support email address
to your project in project settings. Open link
https://console.firebase.google.com/
Select Your project and open settings tab.
Provide a valid support email and restart your application now.

Check if SHA-1 fingerprints are added to the firebase project settings. If not,find SHA-1 fingerprint using
https://developers.google.com/android/guides/client-auth
Also, find the SHA-1 fingerprint of release key using
keytool -list -v -keystore <keystore path>
Remove <keystore path> with the path of the key store.
Then add both SHA-1 fingerprints to firebase projects settings.
NB: Don't forget to replace google-services.json with updated google-services.json with new fingerprints. I lost two days on that.
While debug
Android studio automatically generate ~/.android/debug.keystore on first debug build and use it to sign the app.
To get the SHA-1 run (password android) (doc):
keytool -exportcert -list -v -alias androiddebugkey -keystore ~/.android/debug.keystore
This SHA-1 should be added to the app settings at firebase to allow usage of google sign in capabilities while testing debug build.

Support email and also all project and privacy links are necessary for Google SignIn to work, otherwise it throws 12500.
Set it on https://console.developers.google.com/apis/credentials on the bottom of second tab named "OAuth consent screen" - there you'll find three links that need to be configured.
This is not mentioned ANYWHERE in the Firebase guides.

Correct SHA key is saved on Firebase Console.
Download the latest google-service.json
And Last and most important Save OAuth consent under credentials in google api,
OAuth Screen This took a long to figure out.
And it worked fine after this.

Seems your SHA1 is overwritten by Google play store.
Check in your google play store, launch panel, under app signing, see if google play has an additional SHA1 added.
And copy that SHA1, add to your relevant place, would do the job.

In my case, the issue was that my emulator did not have Play Store. I have made the emulator (named API 23) through Visual Studio, because I develop using Xamarin.Forms as well, and in Visual Studio's Android Device Manager you can select if your emulator should have Google Play Store.
Had to create an emulator through Android Studio's AVD and ensure that it had Play Store:
I think the error came from the Wrong SHA1. Please don't forget that the SHA1 is different between release and debug mode in the android studio. Instead of using keytool to get the SHA1, you can use Gradle project -> Task -> android -> signingReport in the android studio (can open it by menu View -> Toolwindow -> gradle ) to get release and debug SHA1. After that, for easy working, you need to create 2 separate credentials with two SHA1 on google cloud console (google just instruct to create 1 using release SHA1, when we develop it will not work since it uses the debug SHA1).
I'm using Firebase Authentication. My SHA-1 was indicated correctly, client id was also correct but I still was getting 12500.
It turned out that my problem was that I didn't indicate Support email in my project settings. (Settings -> General tab -> Your project (Public settings) section).

Go to your project in the Firebase console, open Project Settings, add your SHA certificate fingerprints there. Download the updated google-services.json file and add it to your Projects app folder.
This worked for me.
–
Getting the debug/release key:
keytool -exportcert -list -v -alias [your alias] -keystore [path/to/debug or release.keystore]
Make sure to download the updated google-services.json to your app.

I tried all of the answers and still was getting 12500. It turned out that the solution for me was even simpler - my project has User Type set to internal and I was trying to log in with email outside of my company. So if none of the previous answers work for you, check if you have User Type set to internal or external and if you try to log in with acceptable account.
When your app authenticates with a backend server or accesses Google APIs from your backend server, then you must pass the OAuth 2.0 client ID that was created for your server to the requestIdToken method when you construct the GoogleSignInOptions object, for accessing the user's basic profile information. Also, don't forget to submit the support email in the OAuth consent screen found in the Credentials page in the API Console.
After I tried all solutions above and nothing has worked.
I found that I am requesting scope that is not mentioned in the cloud.
These is my code
final GoogleSignIn googleSignIn = new GoogleSignIn(
scopes: [
'https://www.googleapis.com/auth/userinfo.email',
'https://www.googleapis.com/auth/userinfo.profile',
'https://www.googleapis.com/auth/openid',
'https://www.googleapis.com/auth/youtube.force-ssl'
After I removed all scopes, it worked.
My scopes section was empty:
Scopes tab can be found here: https://console.cloud.google.com/apis/credentials/consent/edit
Solution: Before executing ionic cordova build android specify the signing properties
Step-1: Generate a debug keystore file
Execute the command
keytool -exportcert -list -v -alias androiddebugkey -keystore ~/.android/debug.keystore
Use password: android
Step-2: Copy the keystore file(debug.keystore) from ~/.android to platform/android directory of your current project
Step-3: Create a file named release-signing.properties in the platform/android directory
Step-4: Add the contents in the file
storeFile=debug.keystore
keyAlias=androiddebugkey
storePassword=android
keyPassword=android
Note: These are the default values. If you have provided custom alias and password then use them accordingly.
Step-5: Now build ionic cordova build android
I experienced the same problem after opening my project on another computer (different Android Studio).
In my case, I solved it using the Firebase Assistant, which I had used to setup Firebase initially.
Opened the Firebase Assistant (Tools > Firebase) and selecting Authentication > Connect.
This reconnected the project to Firebase and updated the configs
I was stuck in the Google Login issue since 2 week, finally sorted it well .let me explain the reason.
The issue was related with firebase. In firebase , they mentioned a field "support email " as optional . But once i added it (any of your personal email) ,the issue sorted and i got the response .
If your getting an error as 12501 , then it is related to settings in your google account.
Generate Client Id in your Google Project.
Provide proper SHA-1 key for that Client Id. (debug / release)
Provide proper package name for that Client Id.
Make sure you have generated Client Id in strings.xml, google-services.json or credentials.json file.
https://developers.google.com/identity/sign-in/android/sign-in
follow this api documentation but keep in mind that inside WEB_CLIENT_ID use the value of client id which is generated inside google-services.json file.
