Something went wrong with Google Auth only on Android

Issue

My firebase authentication used to work smoothly on my IONIC app on both iOS and Android.

Testing on Android after quite a few changes working on IOS side, I can no longer make a google login, though it still works well on iOS it gives me this on Android.

I already checked my SHA1 and SHA256 configuration in firebase console. Loging in with google also works on a web browser. It only fails on Android.

Any suggestion is welcome.

Solution

I had the same problem in the Ionic Capacitor for android version...

Check if your SKD was automatically updated...

I don't know why it changed my SHA-1 run the command to get the SHA-1 and compare with the atual in your firebase (mine was different)

-> keytool -exportcert -list -v -alias androiddebugkey -keystore %USERPROFILE%.android\debug.keystore

go inside your firebase console (console.firebase.google.com) include the new SHA-1 and download your new google-service.json, change the file in your project and try again - for me works fine

The IOS application works fine due to the firebase didnt need the sha-1, but only the package ID

I Checked again and found that I created a new key for my project, this changed the SHA-1, so I included the SHA-1 in firebase, both for debug and release, after this, google login returned to work

keytool -list -v -keystore C:\Users\biel7\.android\Release.jks -alias Release

using the command above, returns my release SHA-1, because in my case when i tried to create the release APK the google login stopped works
