Firebase authentication: listen for failures

I've been trying to listen fail events for user authentication. For testing purpose I closed my internet connection and try to sign up. Neither

onFailureListener
or
!task.isSuccessful
invokes. So how do you guys listen for failed events?

Answer

Firebase doesn't response listener when no internet, for check internet connection you can do it programmatically

if(isNetworkAvailable()){
    //
    // Authentication with Firebase
    // 
}else{
    //Display message/aleart "No internet connection" to user
}

To check isNetworkAvailable(), please see HERE
