Средства бросает ошибка при получении электронной почты Facebook? –
не бросает никаких исключений, не показывает никаких электронных данных в тосте. thats my problem – Kumar
Возможно, вам нужно обновить профиль, по которому вы входите, поскольку иногда вы не устанавливаете идентификатор электронной почты в своем профиле, чтобы не показывать ничего, что я тоже пережил по той же проблеме. –
