Я создавал приложение с аутентификацией firebase. Сначала все шло хорошо, но позже, когда я открываю приложение, оно немедленно отключается. Я попытался перезапустить Android studio, но ничего не произошло. Я только понимаю, что это что-то о макете, но не могу понять, в чем реальная проблема.

Я не знаю, что вызывает эту ошибку.

android:textColor="#ffff" Цвет текста для вашей кнопки неверен. Шестнадцатеричные цвета должны содержать только 3 или 6 символов или 8, если вы применяете альфа.
