'fruitTable не имеет столбец с именем _fruitcalorie' – Selvin

Перейти к настройкам приложения в Android и очистить данные приложения и попробуйте еще раз. – papaiatis

yes.i видел ошибку. что это значит? где в моем коде есть ошибка? и где установлена установка sir? – Riyas2329

Если вы обновили структуру таблицы и добавили новый столбец, вам необходимо удалить приложение, чтобы переустановить его для внесения изменений.

Чтобы удалить Гото Настройки-> Application-> Управление приложениями -> выбрать приложение -> Удалить/ClearData

Удаление и переустановка средств просто закрыть эмулятор и снова запустить снова? – Riyas2329
