I am using Firebase Authentication for authenticating user in my application.
Everything was working fine till I was working on debug build of my application. But the moment I have uploaded the signed apk in playstore, my user authentication service always fails with "Developer Error" message.
On some web research, I find out that I need to generate SHA certificate for my signed apk also. I have generated SHA with locally created ".jks" file, which I have used to sign my application locally before uploading. I have added the generated SHA keys to firebase project console and generated new google-services.json file. Even this approach has not helped me.
I am suspecting that this is happening because I am using "Google Play App Signing (https://developer.android.com/studio/publish/app-signing.html)" which is again changing the certificate. Can anyone please help me and let me know what is the right process for updating SHA keys for release apk.
If play store is doing the app-signing, then how can it be the part of "google-services.json" where SHA keys must be mentioned beforehand?
Please help!!!
