Facebook Login Usage

#

To log in with the Facebook account build a FacebookAuth object and call the signIn() method. Observe the auth result with any LifecycleOwner instance.

FacebookAuth.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 
        }
    })
