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

I tried another solutions but didn't like them.

What about this:

if (!task.isSuccessful()) {

    Exception exc = task.getException();

    if (exc.getMessage().contains("The email address is badly formatted.")) {
        etUser.setError(getString(R.string.error_wrong_email));
        etUser.requestFocus();
    }
    else
    if (exc.getMessage().contains("There is no user record corresponding to this identifier. The user may have been deleted.")) {
        etUser.setError(getString(R.string.error_user_not_exist));
        etUser.requestFocus();
    }
    else
    if (exc.getMessage().contains("The password is invalid or the user does not have a password")) {
        etPass.setError(getString(R.string.error_wrong_password));
        etPass.requestFocus();
    }


    Log.w(TAG, "signInWithEmail:failed", task.getException());


    Toast.makeText(AuthActivity.this, R.string.auth_failed,
            Toast.LENGTH_SHORT).show();
}
