Google Sign In

Sign In

To sign in with the Google account build a GoogleAuth object and call the signIn() method. Observe the auth result with any LifecycleOwner instance. The signIn() method returns the LiveData object with the AuthResult value type

GoogleAuth.Builder(this)
    .requestEmail()
    .requestProfile()
    .enableSmartLock()
    .build()
    .signIn()
    .observe(this, Observer { authResult ->
        if (it.isSuccess) {
            // Do your further stuff with the [authResult.account] here
        } else {
            // Handle the [authResult.exception] here 
        }
    })

Call the enableSmartLock() if you want to use Smart Lock for Passwords on Android

Sign Out

Call the signOut() method in the GoogleAuth object. The observable value is Status

googleAuth.logOut()
    .observe(this, Observer { status ->
        if (it.success) {
            // The user has been signed out
        } else {
            // Show the [status.message] if needed
            // Do your stuff on error 
        }
    })

Revoke access

To get access to the revokeAccess() method you need to cast the googleAuth to the GoogleAuth because of the googleAuth represents the abstraction layer class SocialAuth

(googleAuth as GoogleAuth).revokeAccess()
    .observe(this, Observer { status -> 
        if (status.success) {
            // Do your stuff on success
        } else {
            // Do your stuff on error
        }
    })
