Error in Facebook & Google Login with released signed Apk


I have created an app with facebook & google login. I have been following the guide on Ionic Documentation as well as on Medium & [Ionic Academy][([] and for google this video it works perfectly while debugging an any devices but after signing the release apk both login shows error.

Facebook error Says " Error logging into Facebook [Object Object] "

Google Error says " Error 10 "

I have also went through this solution but couldn’t succeed.

Any help is highly appreciated!!

For Google login you need to add SHA1 keys in firebase console…

How do i do that? Can u please ref a link or documentation?
