Question

GoogleErrorcode : DEVELOPERERROR

Answer 1

Please check if Google Play App Signing is enabled from the Google Play Console -> Release Management -> App Signing.
Please try below steps:
1] You have to copy the SHA1 from the 'App signing certificate' section and need to add it to the Firebase projects general settings section.
2] Afterward need to regenerate the json file and add it to the project.
3] Re-generate the apk and the error will get resolved.

If folks are still having this issue and have stumbled across this as i did. Here's what i figured out for my react native android firebase project
THERE ARE MULTIPLE SHA-1's TO ADD IN FIREBASE
1. SHA-1 For Release Variant
This is found in the Keystore file. You would have to add it to your Firebase Console Project Settings
a. Get release variant SHA-1 by running command below from you RN project root
$ cd android && ./gradlew signingReport
b. Add the release SHA-1 from here to your Firebase Console Project Settings
2.SHA-1 After you upload to google play store for testing / prod rollout
a .SHA-1 is found in the left nav of your google playstore console.
Setup -> App signing -> App signing key certificate
b. Add this to your Firebase Console Project Settings
for google sign in to work in testing / prod

Answer 3

Solved by adding release keystore SHA-1 to firebase console.
Use below command to create release SHA-1 and Add it to firebase console:
keytool -list -v -keystore {keystore_name} -alias {alias_name}
Note : Apk not need to create again.

Yesterday same problem occurred to me.
Google has released a new signing service in playstore publish console in which google will signin your app with his keystore. After signing , it will give you a new SHA which you have to add in your firebase account.

Answer 5

I have got a solution to this problem.
You have to put both SHA key i.e. SHA for debug Keystore file and SHA for release jks file, into the firebase project setting.
Go to: https://console.firebase.google.com/
Now choose your project
Click the setting button near Project Overview
Choose Project Setting
Enter both SHA1 (debug SHA1 and release SHA1) in SHA certificate fingerprint
Save it
Download the google-services.json file
Run npx react-native run-android --variant=release in terminal
It worked for me very well.

There is a new signing service from Google in the Playstore publish console, in which Google will sign your app with his keystore. After signing, it will give you a new SHA, which you need to connect to your Firebase account.
Go to Google play store ->
Release -> Setup -> App Integrity
Copy: SHA-1 certificate fingerprint from "App signing key certificate"
Add this into Firebase Project
Project Setting -> Select your app -> Add Fingerprints and Paste it here
