How to catch a Firebase Auth specific exceptions

Question

Using Firebase, how do I catch a specific exception and tell the user gracefully about it? E.g :

FirebaseAuthInvalidCredentialsException: The email ad

Answer 1

If you simply want display a message to the user this works. Simple and Elegant:

if (!task.isSuccessful()) {
    Log.w(TAG, "signInWithEmail:failed", task.getException());
    Toast.makeText(LoginActivity.this, "User Authentication Failed: " + task.getException().getMessage(), Toast.LENGTH_SHORT).show();
}

It appears that the .getMessage() method converts the exception to a usable format for us already and all we have to do is display that somewhere to the user.
