Я новичок в программировании Android.Я успешно интегрировал вход в Google и успешно передал данные в другое действие.Но когда я возвращаюсь к активности через навигационный ящик, где я передавал данные, он высевает пустой экран.Я хочу сохранить профиль пользователя в этой деятельности.Я хочу сохранить информацию о пользователе, нажав кнопку «Сохранить» в приложении, чтобы отобразить его как профиль пользователя.Пожалуйста, помогите мне в решении этой проблемы.Спасибо, заранее за решение.
Вот мои java-файлы и XML-файлы.
