2. To resolve google signin error: “Google sign in error 12500” Or “Non-recoverable error occurred”:

Make sure to:
    - add SHA1 key for release and debug on firebase console(see above point for SHA1 key generation)
    - add Support Email on the firebase console
    - Add Application Homepage link, Application Privacy Policy link, Application Terms of Service link on https://console.developers.google.com/apis/credentials
    - If app is on PlayStore(live or in beta),
        -Go to https://play.google.com/apps/publish
        -select your app
        -From Left menu, go to release management -> App Signing and from the “App signing certificate” section, copy the SHA-1 key and update the key on the firebase console.

	We can connect our app with the firebase using Android studio firebase assistant, which automatically adds our SHA1 key to the firebase:
