check the same firebase project in google cloud and cross-verify SHA-1 keys in firebase to google cloud, if see any old SHA-1 keys delete them or if your SHA-1 key from Firebase is not in google cloud then add sha-1 from add credential option. if still same error then create a new firebase project and then try again.

CodePudding user response：

First, get the SHA-1 and SHA-256 keys. Run the following commands in your project root terminal window (from vscode or Android studio) one by one

cd android
./gradlew signingReport

this will take few minutes then you'll be popped up with a screen similar to this.

Copy SHA-1 and SHA-256 keys and paste it in firebase project settings at

Scroll down to find your android app then click on Add fingerprint

Note: Make sure to add both the keys, else it may not work as desired.

Happy coding :)
