If you are adding all the SHA-1 Finger prints in firebase still you are getting error.then (I was facing this problem. after this steps it's resolved.)Try this steps:
1.Go to Google Console API credentials Page.
2.Click the credentials in the Left tab.
3.Already two default Android and Web OAuth client Id will be present. You have to create One Android Client and One Web 2.0 Client.
4.Go to Firebase.In project setting ,download google-services.json and paste in app folder.
(Everything is fine but still you are cannot signin google means maybe OAuth problem. so make sure to create Android and Web client ID.Finally in credential page you have 2 Android Client and Two Web client Id.)
Generate the debug key first:
keytool -exportcert -list -v \
-alias androiddebugkey -keystore ~/.android/debug.keystore
Then paste the SHA1 to the Firebase or Google project Settings in the fingerprint section.
