 ## How to build the Android app

+_tested on Mac OS_
 
 The Android app has the following requirements:
 * JDK 11
 * Android platform SDK 33
-* CMake 3.25.0
+* cmake 3.25.0
 
-After you have installed QT, QT Creator, and Android Studio, you need to configure QT Creator correctly.
+After you have installed QT, QT Creator and Android Studio installed, you need to configure QT Creator correctly. Click in the top menu bar on `QT Creator` -> `Preferences` -> `Devices` and select the tab `Android`. 
+    * set path to jdk 11
+    * set path to Android SDK ($ANDROID_HOME)
 
-- Click in the top menu bar on `QT Creator` -> `Preferences` -> `Devices` and select the tab `Android`.
-- Set path to JDK 11
-- Set path to Android SDK (`$ANDROID_HOME`)
+In case you get errors regarding missing SDK or 'sdkmanager not running', you cannot fix them by correcting the paths and you have some spare GBs on your disk, you can let QT Creator install all requirements by choosing an empty folder for `Android SDK location` and click on `Set Up SDK`. Be aware: This will install a second Android SDK and NDK on your machine!

If you have some spare GBs on your disk, you can let QT Creator install all requirements by choosing an empty folder for `Android SDK location` and clicking on `Set Up SDK`. Be aware: This will install a second Android SDK and NDK on your machine! 
-Double-check that the right CMake version is configured:  Click on `QT Creator` -> `Preferences` and click on the side menu on `Kits`. Under the center content view's `Kits` tab, you'll find an entry for `CMake Tool`. If the default selected CMake version is lower than 3.25.0, install on your system CMake >= 3.25.0 and choose `System CMake at <path>` from the drop-down list. If this entry is missing, you either have not installed CMake yet or QT Creator hasn't found the path to it. In that case, click in the preferences window on the side menu item `CMake`, then on the tab `Tools` in the center content view, and finally on the button `Add` to set the path to your installed CMake. 
-Please make sure that you have selected Android Platform SDK 33 for your project: click in the main view's side menu on `Projects`, and on the left, you'll see a section `Build & Run` showing different Android build targets. You can select any of them, Amnezia VPN's project setup is designed in a way that all Android targets will be built. Click on the targets submenu item `Build` and scroll in the center content view to `Build Steps`. Click on `Details` at the end of the headline `Build Android APK` (the `Details` button might be hidden in case the QT Creator Window is not running in full screen!). Here we are: Choose `android-33` as `Android Build Platform SDK`.

+
+That's it you should be ready to compile the project from QT Creator!
 
 ### Development flow
+After you've hit the build button, QT-Creator copies the whole project to a folder in the repositories parent directory. The folder should look something like `build-amnezia-client-Android_Qt_<version>_Clang_<architecture>-<BuildType>`.
+If you want to develop Amnezia VPNs Android components written in Kotlin, such as components using system APIs, you need to import the generated project in Android Studio with `build-amnezia-client-Android_Qt_<version>_Clang_<architecture>-<BuildType>/client/android-build` as the projects root directory. While you should be able to compile the generated project from Android Studio, you cannot work directly in the repository's Android project. So whenever you are confident with your work in the generated project, you'll need to copy and paste the affected files to the corresponding path in the repositories Android project so that you can add and commit your changes!

-You may face compiling issues in QT Creator after you've worked in Android Studio on the generated project. Just do a `./gradlew clean` in the generated project's root directory (`<path>/client/android-build/.`) and you should be good to go.

-## Особенности
-
-- Простой в использовании — введите IP-адрес, SSH-логин и пароль, и Amnezia автоматически установит VPN-контейнеры Docker на ваш сервер и подключится к VPN.
-- Классические VPN-протоколы: OpenVPN, WireGuard и IKEv2.
-- Протоколы с маскировкой трафика (обфускацией): OpenVPN с плагином [Cloak](https://github.com/cbeuw/Cloak), Shadowsocks (OpenVPN over Shadowsocks), [AmneziaWG](https://docs.amnezia.org/documentation/amnezia-wg/) and XRay.
-- Поддержка Split Tunneling — добавляйте любые сайты или приложения в список, чтобы включить VPN только для них.
-- Поддерживает платформы: Windows, macOS, Linux, Android, iOS.
-- Поддержка конфигурации протокола AmneziaWG на [бета-прошивке Keenetic](https://docs.keenetic.com/ua/air/kn-1611/en/6319-latest-development-release.html#UUID-186c4108-5afd-c10b-f38a-cdff6c17fab3_section-idm33192196168192-improved).

-## Технологии
-
-AmneziaVPN использует несколько проектов с открытым исходным кодом:
-
-- [OpenSSL](https://www.openssl.org/)
-- [OpenVPN](https://openvpn.net/)
-- [Shadowsocks](https://shadowsocks.org/)
-- [Qt](https://www.qt.io/)
-- [LibSsh](https://libssh.org)
-- и другие...
-
-## Проверка исходного кода
-После клонирования репозитория обязательно загрузите все подмодули.
-
-```bash
-git submodule update --init --recursive
-```
-
-
-## Разработка
-Хотите внести свой вклад? Добро пожаловать!
-
-### Помощь с переводами
-
-Загрузите самые актуальные файлы перевода.
-
-Перейдите на [вкладку "Actions"](https://github.com/amnezia-vpn/amnezia-client/actions?query=is%3Asuccess+branch%3Adev), нажмите на первую строку. Затем прокрутите вниз до раздела "Artifacts" и скачайте "AmneziaVPN_translations".
-
-Распакуйте этот файл. Каждый файл с расширением *.ts содержит строки для соответствующего языка.
-
-Переведите или исправьте строки в одном или нескольких файлах *.ts и загрузите их обратно в этот репозиторий в папку ``client/translations``. Это можно сделать через веб-интерфейс или любым другим знакомым вам способом.
-
-### Сборка исходного кода и деплой
-Проверьте папку deploy для скриптов сборки.
-
-### Как собрать iOS-приложение из исходного кода на MacOS
-1. Убедитесь, что у вас установлен Xcode версии 14 или выше.
-2. Для генерации проекта Xcode используется QT. Требуется версия QT 6.6.2. Установите QT для MacOS здесь или через QT Online Installer. Необходимые модули:
-- MacOS
-- iOS
-- Модуль совместимости с Qt 5
-- Qt Shader Tools
-- Дополнительные библиотеки:
- - Qt Image Formats
- - Qt Multimedia
- - Qt Remote Objects
-
-   
-3. Установите CMake, если это необходимо. Рекомендуемая версия — 3.25. Скачать CMake можно здесь.
-4. Установите Go версии >= v1.16. Если Go ещё не установлен, скачайте его с  [официального сайта](https://golang.org/dl/) или используйте Homebrew. Установите gomobile:
-
-```bash
-export PATH=$PATH:~/go/bin
-go install golang.org/x/mobile/cmd/gomobile@latest
-gomobile init
-```
-
-5. Соберите проект:
-```bash
-export QT_BIN_DIR="<PATH-TO-QT-FOLDER>/Qt/<QT-VERSION>/ios/bin"
-export QT_MACOS_ROOT_DIR="<PATH-TO-QT-FOLDER>/Qt/<QT-VERSION>/macos"
-export QT_IOS_BIN=$QT_BIN_DIR
-export PATH=$PATH:~/go/bin
-mkdir build-ios
-$QT_IOS_BIN/qt-cmake . -B build-ios -GXcode -DQT_HOST_PATH=$QT_MACOS_ROOT_DIR
-```
-Замените <PATH-TO-QT-FOLDER> и <QT-VERSION> на ваши значения.
-
-Если появляется ошибка gomobile: command not found, убедитесь, что PATH настроен на папку bin, где установлен gomobile:
-```bash
-export PATH=$(PATH):/path/to/GOPATH/bin
-```
-
-6. Откройте проект в Xcode. Теперь вы можете тестировать, архивировать или публиковать приложение.
-   
-Если сборка завершится с ошибкой:
-```
-make: *** 
-[$(PROJECTDIR)/client/build/AmneziaVPN.build/Debug-iphoneos/wireguard-go-bridge/goroot/.prepared] 
-Error 1
-```
-Добавьте пользовательскую переменную PATH в настройки сборки для целей AmneziaVPN и WireGuardNetworkExtension с ключом `PATH` и значением `${PATH}/path/to/bin/folder/with/go/executable`, e.g. `${PATH}:/usr/local/go/bin`.
-
-Если ошибка повторяется на Mac с M1, установите версию CMake для архитектуры ARM:
-```
-arch -arm64 brew install cmake
-```
-
- При первой попытке сборка может завершиться с ошибкой source files not found. Это происходит из-за параллельной компиляции зависимостей в XCode. Просто перезапустите сборку.
-
-
-## Как собрать Android-приложение
-Сборка тестировалась на MacOS. Требования:
-- JDK 11
-- Android SDK 33
-- CMake 3.25.0
-  
-Установите QT, QT Creator и Android Studio.
-Настройте QT Creator:
-
-- В меню QT Creator перейдите в  `QT Creator` -> `Preferences` -> `Devices` ->`Android`.
-- Укажите путь к JDK 11.
-- Укажите путь к Android SDK (`$ANDROID_HOME`)
-
-Если вы сталкиваетесь с ошибками, связанными с отсутствием SDK или сообщением «SDK manager not running», их нельзя исправить просто корректировкой путей. Если у вас есть несколько свободных гигабайт на диске, вы можете позволить Qt Creator установить все необходимые компоненты, выбрав пустую папку для расположения Android SDK и нажав кнопку **Set Up SDK**. Учтите: это установит второй Android SDK и NDK на вашем компьютере!
-
-Убедитесь, что настроена правильная версия CMake: перейдите в **Qt Creator -> Preferences** и в боковом меню выберите пункт **Kits**. В центральной части окна, на вкладке **Kits**, найдите запись для инструмента **CMake Tool**. Если выбранная по умолчанию версия CMake ниже 3.25.0, установите на свою систему CMake версии 3.25.0 или выше, а затем выберите опцию **System CMake at <путь>** из выпадающего списка. Если этот пункт отсутствует, это может означать, что вы еще не установили CMake, или Qt Creator не смог найти путь к нему. В таком случае в окне **Preferences** перейдите в боковое меню **CMake**, затем во вкладку **Tools** в центральной части окна и нажмите кнопку **Add**, чтобы указать путь к установленному CMake.
-
-Убедитесь, что для вашего проекта выбрана Android Platform SDK 33: в главном окне на боковой панели выберите пункт **Projects**, и слева вы увидите раздел **Build & Run**, показывающий различные целевые Android-платформы. Вы можете выбрать любую из них, так как настройка проекта Amnezia VPN разработана таким образом, чтобы все Android-цели могли быть собраны. Перейдите в подраздел **Build** и прокрутите центральную часть окна до раздела **Build Steps**. Нажмите **Details** в заголовке **Build Android APK** (кнопка **Details** может быть скрыта, если окно Qt Creator не запущено в полноэкранном режиме!). Вот здесь выберите **android-33** в качестве Android Build Platform SDK.
-
-### Разработка Android-компонентов
-
-После сборки QT Creator копирует проект в отдельную папку, например, `build-amnezia-client-Android_Qt_<version>_Clang_<architecture>-<BuildType>`. Для разработки Android-компонентов откройте сгенерированный проект в Android Studio, указав папку `build-amnezia-client-Android_Qt_<version>_Clang_<architecture>-<BuildType>/client/android-build` в качестве корневой.
-Изменения в сгенерированном проекте нужно вручную перенести в репозиторий. После этого можно коммитить изменения.
-Если возникают проблемы со сборкой в QT Creator после работы в Android Studio, выполните команду `./gradlew clean` в корневой папке сгенерированного проекта (`<path>/client/android-build/.`).
