+# НТО 2024. II отборочный этап. Командные задани — клиентская часть
+
+## 📖 Предыстория
+В компании S контроль доступа в офис осуществляется с помощью СКУД (системы контроля управления доступом). На данный момент у каждого сотрудника компании есть карта-пропуск с NFC меткой. А у каждой входной двери есть считыватель с обеих сторон. При поднесении карты к считывателю, дверь открывается, а информация о времени входа или выхода сотрудника фиксируется в базе данных. 
+Администрации компании S требуется мобильное приложение, как для рядовых сотрудников, так и для администрации с возможностью просмотра посещений и работой электронного пропуска как временной замены обычного (при помощи сканировании QR кода, который находится на считывателе). Поскольку в приложении есть возможность использовать телефон как пропуск - то к данному приложению повышенные требования к безопасности всех данных, находящихся внутри него.
+
+
+
+## 📋 Системные требования
+
+| **Параметр**                | **Требование**                                  |
+|-----------------------------|-------------------------------------------------|
+| **Минимальная версия Android** | 9.0 (API 28)                                    |
+| **Целевая версия Android**    | 14 (API 34)                                     |
+| **Поддерживаемые устройства** | смартфоны, планшеты                             |
+| **Ориентация экранов**         | портретная                                      |
+| **Языки**                    | русский, английский                             |
+| **Разрешения**               | доступ к ифнтернету, камера (при необходимости) |
+
+
+
+## 📱 Техническое задание
+Требуется разработать нативное мобильное приложение, которое будет содержать следующие экраны.
+
+
+### 1. Экран авторизации
+
+> Данный экран должен быть показан при первом входе в приложение, а также в ситуациях, когда пользователь не зарегистрировался в приложении.
+#### Элементы, которые должны присутствовать на экране:
+- Поле ввода (`id/username`), в котором пользователю необходимо ввести свой логин.
+- Кнопка входа (`id/login`), по нажатию на которую пользователь авторизуется в системе.
+- По умолчанию скрытое (`GONE`) текстовое поле с ошибкой (`id/error`).
+
+#### Требования к компонентам:
+1. В пустом поле ввода должна отображаться подсказка, что требуется ввести пользователю.
+2. Если хотя бы одно из условий ниже соблюдено - кнопка должна быть неактивной:
+    - Поле ввода пустое.
+    - Количество символов менее 3х.
+    - Логин начинается с цифры.
+    - Логин содержит символы, отличные от латинского алфавита и цифр.
+3. Поле ввода и кнопку должно быть видно при раскрытии клавиатуры.
+4. - При нажатии на кнопку входа необходимо проверить, что данный пользователь существует с помощью запроса `api/<LOGIN>/auth` (подробное описание представлено в техническом задании серверной части).
+5. В случае отсутствия логина или любой другой неполадки - необходимо вывести ошибку, пока пользователь не изменит текстовое поле или повторно не нажмёт на кнопку.
+6. После нажатия на кнопку - логин должен быть сохранён и при следующем открытии приложения экран авторизации не должен быть показан.
+7. После нажатия на кнопку - при нажатии стрелки назад - экран авторизации не должен быть показан повторно.
+8. Экран авторизации показывается только в случае, если пользователь неавторизован.
+
+
+
+
+
+### 2. Главный экран
+
+> Данный экран содержит общую информацию о пользователе:
+>- ФИО
+>- Фото
+>- Должность
+>- Время последнего входа
+
+#### Элементы, которые должны присутствовать на экране:
+- Текстовое поле (`id/fullname`), в котором написано имя пользователя.
+- Изображение (`id/photo`), на котором отображено фото пользователя.
+- Текстовое поле (`id/position`), в котором написана должность пользователя.
+- Текстовое поле (`id/lastEntry`), в котором написана дата и время последнего входа пользователя.
+- Кнопка (`id/logout`) для выхода пользователя из аккаунта.
+- Кнопка (`id/refresh`) для обновления данных.
+- Кнопка (`id/scan`) для сканирования QR кода.
+- По умолчанию скрытое текстовое поле с ошибкой (`id/error`).
+
+#### Требования к компонентам:
+- В случае любой ошибки необходимо скрыть все элементы, кроме текстового поля с ошибкой и кнопки обновления данных.
+- Для получения данных необходимо использовать сетевой запрос `/api/<LOGIN>/info`.
+- Формат даты и времени последнего входа пользователя: `yyyy-MM-dd HH:mm` (например: 2024-02-31 08:31). Время необходимо отображать с сервера, без поправок на часовой пояс или локальное смещение.
+- При нажатии на кнопку выход все данные (если есть) пользователя должны быть очищены, а приложение должно открыть экран авторизации.
+- При нажатии кнопки сканирования необходимо открыть экран сканирования QR кода.
+- При нажатии на кнопку обновления данных - необходимо повторно вызывать сетевой запрос для получения актуальных данных.
+
+
+
+### 3. Экран сканирования QR-кода
+
+> Данный экран позволяет отсканировать код на турникете и войти с помощью смартфона. В данном случае данный экран будет уже написан и представлен dам в готовом виде в заготовке. Вам необходимо только подписаться на его результат с помощью **Result API** и обработать считанные данные из QR кода. **Данный экран нельзя модифицировать. Он поставляется как есть.**
+
+
+
+### 4. Экран с результатом сканирования QR кода
+
+> На данном экране необходимо вывести успешность или неуспешность входа с помощью метода QR кода.
+
+#### Элементы, которые должны присутствовать на экране:
+- Текстовое поле (`id/result`), где содержится текст об успешности или неуспешности входа.
+- Кнопка (`id/close`) для закрытия данного экрана.
+
+#### Требования к компонентам:
+- В случае, если результат пришёл пустым или со статусом “Отмена” - необходимо вывести пользователю текст:  
+  *"Вход был отменён/Operation was cancelled"*
+- В случае, если данные пришли, то необходимо их отправить на сервер с запросом `api/<LOGIN>/open`, добавив данные из результата и получить ответ.
+- Если сервер ответил успешно - то отображаем текст:  
+  *"Успешно/Success"*
+- Если сервер ответил любой ошибкой - то отображаем текст:  
+  *"Что-то пошло не так/Something wrong"*
+- Кнопка закрытия всегда открывает главный экран.
+
+
+
+## 🛠 Решение
+
+Необходимо загрузить свое решение в систему [по ссылке](https://innovationcampus.ru/lms/mod/quiz/view.php?id=2149).
+
+Отметим, что работу необходимо осуществлять в представленных проектах-заготовках (шаблонах). 
+
+
+
+## ✅ Особенности оценивания
+
+Оценивание происходит с помощью автоматической системы тестирования, которая в автоматическом режиме находит элементы и взаимодействует с ними (именно для этого у каждого элемента указан уникальный идентификатор, по которому будет производится поиск). Каждый тест происходит с чистой установки приложения.
+В случае тестирования сервера на него поочередно отправляются команды, описанные в API и ожидаются определенные корректные ответы.
+Сервер и приложение тестируются независимо.

+# Файл для управления дистрибутивом Gradle
+
+Данный репозиторий необходим для поддержки актуальности дистрибутива Gradle в проектах. Данный проект необходимо подключать подмодулём и использовать во всех проектах.
+
+## Как обвновлять дистрибутив
+
+Перед обновлением необходимо удостоверится, что версия самого Gradle установлена не ниже, чем в дистрибутиве. Сделать это можно [здесь](https://sicampus.ru/gitea/core/dependecies/src/branch/main/src/main/java/Version.kt#L16).
+
+Процесс обновления выглядит следуюющим образом:
+1. В начале обновляем саму версию Gradle ([в этом репозитории](https://sicampus.ru/gitea/core/dependecies)).
+2. Обновлем ссылку на дестрибутив и проверяем совместимость.

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.
