Я создал аутентификацию входа / регистрации с использованием Firebase и заполняю данные, используя общие предпочтения, такие как полное имя и адрес электронной почты в DashboardActivity. но проблема в том, что когда пользователь1 создает новую учетную запись и имя входа, данные заполнены успешно ... и пользователь2 создает другую новую учетную запись и снова входит в систему, данные заполнены успешно ... но проблема заключается в том, что снова пользователь 1 входит в систему и Go в панели инструментов, после чего он показывает пользователя 2 детали
Это Моя проблема
Это Мой код
