+
+## Build Instructions
+
+### Prerequisites
+
+1. **Initialize submodules:**
+   ```bash
+   git submodule update --init --recursive
+   ```
+   This MUST be done first before any build attempts.
+
+2. **Set up environment variables:**
+   ```bash
+   export ANDROID_NDK_ROOT=/path/to/ndk/27.0.12077973
+   export PATH=${PATH}:${ANDROID_NDK_ROOT}/toolchains/llvm/prebuilt/linux-x86_64/bin/:${ANDROID_NDK_ROOT}
+   ```
+   Note: Path format varies by OS (linux-x86_64, darwin-x86_64, etc.)
+
+3. **Install Rust toolchains:**
+   ```bash
+   scripts/install-toolchains.sh
+   ```
+   Required for building the native Rust components.
+
+4. **Build native libraries:**
+   ```bash
+   scripts/ndk-make.sh
+   ```
+   **IMPORTANT:** First run takes 30-60 minutes as it builds for all architectures (armeabi-v7a, arm64-v8a, x86, x86_64).
+   For faster development builds, build for a single architecture:
+   ```bash
+   scripts/ndk-make.sh armeabi-v7a
+   ```
+
+5. **Build APK:**
+   ```bash
+   ./gradlew assembleDebug
+   ```
+   Build time: ~2-5 minutes after native libraries are built.
+
+### Build Flavors
+
+- **gplay:** Google Play version with Firebase Cloud Messaging (applicationId: `com.github.arcanechat`)
+- **foss:** F-Droid version without proprietary services (applicationId: `chat.delta.lite`)
+
+### Build Outputs
+
+- Debug APKs: `build/outputs/apk/gplay/debug/` and `build/outputs/apk/fat/debug/`
+- Release APKs require signing configuration in `~/.gradle/gradle.properties`
+
+### Common Build Issues
+
+1. **Missing NDK or incorrect version:**
+   - Error: `ANDROID_NDK_ROOT not set` or native library missing
+   - Solution: Install NDK 27.0.12077973 and set ANDROID_NDK_ROOT environment variable
+
+2. **Submodules not initialized:**
+   - Error: Missing deltachat-core-rust files
+   - Solution: Run `git submodule update --init --recursive`
+
+3. **Gradle wrapper validation:**
+   - Always validate gradle wrapper before building: `./gradlew wrapper --gradle-version=current`
+   - Wrapper is validated in CI via `gradle/actions/wrapper-validation@v4`
+
+4. **Clean build issues:**
+   - If build fails, try: `./gradlew clean && scripts/ndk-make.sh && ./gradlew assembleDebug`
+   - Remove `build/` directory if clean doesn't work
+
+## Testing
+
+### Running Unit Tests
+
+```bash
+./gradlew test
+```
+Expected duration: 1-3 minutes
+
+### Running Instrumented Tests
+
+1. **Disable animations** on your device/emulator:
+   - Developer Options → Set "Window animation scale", "Transition animation scale", and "Animator duration scale" to 0x
+   - **CRITICAL:** Tests will fail if animations are enabled
+
+2. **Run tests:**
+   ```bash
+   ./gradlew connectedAndroidTest
+   ```
+   Expected duration: 10-30 minutes depending on device/emulator
+
+### Online Tests
+
+Some tests require real email credentials. Configure in `~/.gradle/gradle.properties`:
+```properties
+TEST_ADDR=youraccount@yourdomain.org
+TEST_MAIL_PW=yourpassword
+```
+
+### UI Tests and Benchmarks
+
+- Located in `src/androidTest/java/com/b44t/messenger/`
+- Test categories: `uitests/online/`, `uitests/offline/`, `uibenchmarks/`
+- Run via Android Studio: Run → Edit Configurations → Android Instrumented Test
+
+## Coding Conventions
+
+### General Guidelines
+
+1. **Embrace existing style:** Match the coding style of the file you're editing
+2. **Minimize changes:** Don't refactor or rename in the same PR as bug fixes/features
+3. **Readable over paradigmatic:** Favor readability over strict Java patterns
+4. **Avoid premature optimization:** Keep things simple and on point
+5. **No excessive abstraction:** Avoid unnecessary factories, one-liner functions, or abstraction layers
+6. **Comments:** Only add comments if they match existing style or explain complex logic
+
+### Architecture
+
+- **UI/Model Separation:** Delta Chat Core (Rust) handles the model layer
+- **High-level interface:** Core provides data in UI-ready form; avoid additional transformations in UI layer
+- **Direct approach:** Prefer direct implementation over excessive class hierarchies
+
+### Key Principles
+
+- Work hard to avoid options and up-front choices
+- Avoid speaking about keys/encryption in primary UI
+- App must work offline and with poor network
+- Users don't read much text
+- Consistency matters
+- Primary UI should only show highly useful features
+
+## Common Development Tasks
+
+### Adding New Features
+
+1. Consider the UX philosophy (minimal options, offline-first, simplicity)
+2. Check if core library changes are needed before implementing in UI
+3. Match existing code style in modified files
+4. Add instrumented tests for UI changes when appropriate
+5. Update relevant documentation
+
+### Modifying Core Integration
+
+- Core library is in `jni/deltachat-core-rust/` submodule
+- Java bindings are in `src/main/java/com/b44t/messenger/Dc*.java`
+- JSON-RPC bindings in `chat.delta.rpc.*` package (generated via dcrpcgen)
+
+### Generating JSON-RPC Bindings
+
+To regenerate JSON-RPC bindings after core changes:
+```bash
+./scripts/generate-rpc-bindings.sh
+```
+**Note:** Requires Rust tooling and [dcrpcgen tool](https://github.com/chatmail/dcrpcgen) installed
+
+### Working with Translations
+
+- Translations managed via Transifex (not in repository)
+- English source strings: `res/values/strings.xml`
+- Don't mix string changes with refactoring
+
+### Debugging Native Code
+
+Decode crash symbols:
+```bash
+$ANDROID_NDK_ROOT/ndk-stack --sym obj/local/armeabi-v7a --dump crash.txt > decoded.txt
+```
+
+## Validation and Quality Checks
+
+### Pre-commit Checks
+
+Before committing changes, always run:
+
+1. **Gradle wrapper validation:**
+   ```bash
+   ./gradlew wrapper --gradle-version=current
+   ```
+
+2. **Build verification:**
+   ```bash
+   ./gradlew assembleDebug
+   ```
+
+3. **Unit tests:**
+   ```bash
+   ./gradlew test
+   ```
+
+4. **Code style:** Match existing code style in modified files (no automatic formatter configured)
+
+### When to Rebuild Native Libraries
+
+Rebuild native libraries (`scripts/ndk-make.sh`) when:
+- Updating deltachat-core-rust submodule
+- Modifying anything in `jni/` directory
+- Changing NDK version
+- After `git clean -fdx` or fresh clone
+
+**DO NOT** rebuild native libraries for:
+- Pure Java/Kotlin code changes
+- Resource file changes
+- Gradle configuration changes (unless changing native library linking)
+- Documentation updates
+
+## WebXDC Support
+
+ArcaneChat has extended WebXDC support:
+- `window.webxdc.arcanechat` - Version detection
+- `sendToChat()` - Extra properties: `subject`, `html`, `type` (sticker/image/audio/video/file)
+- External link support in apps
+- `manifest.toml` - `orientation` field for landscape mode
+
+## Important Files
+
+- `build.gradle` - Main build configuration (Android Gradle Plugin 8.11.1, Java 8 compatibility)
+- `CONTRIBUTING.md` - Contribution guidelines
+- `BUILDING.md` - Detailed build setup instructions
+- `RELEASE.md` - Release process
+- `proguard-rules.pro` - ProGuard configuration (enabled for both debug and release)
+- `google-services.json` - Firebase configuration (gplay flavor only)
+- `settings.gradle` - Gradle settings
+- `.github/workflows/` - CI/CD configuration
+
+## Dependencies and Constraints
+
+- **Java Version:** Java 8 compatibility (do not use Java 9+ features)
+- **Gradle:** Use wrapper (`./gradlew`) to ensure correct Gradle version
+- **NDK:** Must use version 27.0.12077973 (specified in build.gradle)
+- **Min SDK:** 21 (Android 5.0) - code must be compatible
+- **Target SDK:** 36 (Android 16) - test on this API level when possible
+- **ProGuard:** Always enabled - ensure ProGuard rules are correct for new dependencies
+- **Multi-dex:** Enabled - app exceeds 65k method limit
+
+## Package Structure
+
+- `org.thoughtcrime.securesms.*` - Main UI components (legacy namespace from Signal)
+- `com.b44t.messenger.*` - Delta Chat core integration
+- `chat.delta.rpc.*` - JSON-RPC bindings (generated)
+
+## Notes for AI Assistants
+
+- This is a fork of Delta Chat Android with ArcaneChat-specific improvements
+- Maintain compatibility with Delta Chat core library
+- Test on both gplay and foss flavors when making changes
+- Native library must be rebuilt after core changes
+- ProGuard is enabled in both debug and release builds
+- Multi-dex is enabled due to app size
+
+## CI/CD Workflows
+
+### Preview APK Workflow (.github/workflows/preview-apk.yml)
+
+Runs on every pull request to build and upload a preview APK:
+
+1. **Setup steps:**
+   - Checks out repository with submodules
+   - Validates Fastlane metadata
+   - Sets up Rust cache (working-directory: jni/deltachat-core-rust)
+   - Sets up Java 17 (Temurin distribution)
+   - Sets up Android SDK
+   - Caches Gradle dependencies
+   - Sets up NDK r27
+
+2. **Build process:**
+   ```bash
+   scripts/install-toolchains.sh && scripts/ndk-make.sh armeabi-v7a
+   ./gradlew --no-daemon -PABI_FILTER=armeabi-v7a assembleFossDebug
+   ```
+   Note: Builds only armeabi-v7a for faster CI builds
+
+3. **Output:** Uploads APK artifact to GitHub Actions
+
+### Important CI Considerations
+
+- Always validate Gradle wrapper before committing changes
+- Fastlane metadata must be valid (validated in CI)
+- Use `--no-daemon` flag for Gradle in CI environments
+- CI builds use FOSS flavor to avoid Google Services dependencies
+- Expected CI build time: 15-25 minutes for full workflow

+# Building and Testing
+
+This document describes how to set up the build environment,
+build and test the app. Before diving into developing, please
+first read [CONTRIBUTING.md](./CONTRIBUTING.md) for general
+contribution hints and conventions.
+
+Please follow all steps precisely.
+If you run into troubles,
+ask on one of the [communication channels](https://delta.chat/contribute) for help
+
+
+## Check Out Repository
+
+When checking out _deltachat-android_, make sure also to check out the
+subproject _deltachat-core-rust_:
+
+- When using Git, you can do this initially by
+  `$ git clone --recursive https://github.com/deltachat/deltachat-android`
+  or later by `git submodule update --init --recursive`. If you do this in your
+  home directory, this results in the folder `~/deltachat-android` which is just fine.
+
+## Generate JSON-RPC bindings
+
+To generate/update the JSON-RPC bindings (ex. `chat.delta.rpc.*` package)
+install Rust tooling (read sections below) and the [dcrpcgen tool](https://github.com/chatmail/dcrpcgen)
+then generate the code running the script:
+
+```
+./scripts/update-rpc-bindings.sh
+```
+
+## Build Using Nix
+
+The repository contains [Nix](https://nixos.org/) development environment
+described in `flake.nix` file.
+If you don't have Nix installed,
+the easiest way is to follow the [Lix installation instructions](https://lix.systems/install/)
+as this results in a setup with [Flakes](https://nixos.wiki/wiki/Flakes) feature enabled out of the box
+and can be cleanly uninstalled with `/nix/nix-installer uninstall` once you don't need it anymore.
+
+Once you have Nix with Flakes feature set up start the development environment shell:
+```
+nix develop
+```
+Nix development environment contains Rust with cross-compilation toolchains and Android SDK.
+
+To [build an APK](https://developer.android.com/studio/build/building-cmdline) run the following 2 steps.
+Note that the first step may take some time to build for all architectures. You can optionally read 
+[the first comment block in the `ndk-make.sh` script](https://github.com/deltachat/deltachat-android/blob/master/scripts/ndk-make.sh) 
+for pointers on how to build for a specific architecture.
+```
+$ scripts/ndk-make.sh
+$ ./gradlew assembleDebug
+```
+
+Resulting APK files can be found in
+`build/outputs/apk/gplay/debug/` and
+`build/outputs/apk/fat/debug/`.
+
+## Build Using Dockerfile
+
+Another way to build APK is to use provided `Dockerfile`
+with [Docker](https://www.docker.com/) or [Podman](https://podman.io/).
+Podman is a drop-in replacement for Docker that does not require root privileges.
+
+If you don't have Docker or Podman setup yet, read [how to setup Podman](#setup-podman)
+below. If you don't want to use Docker or Podman, read [how to manually install the
+build environment](#install-build-environment).
+
+First, build the image `deltachat-android` by running
+```
+podman build --build-arg UID=$(id -u) --build-arg GID=$(id -g) . -t deltachat-android
+```
+or
+```
+docker build --build-arg UID=$(id -u) --build-arg GID=$(id -g) . -t deltachat-android
+```
+
+Then, run the image:
+```
+podman run --userns=keep-id -it --name deltachat -v $(pwd):/home/app:z -w /home/app localhost/deltachat-android
+```
+or
+```
+docker run -it --name deltachat -v $(pwd):/home/app:z -w /home/app localhost/deltachat-android
+```
+
+You can leave the container with Ctrl+D or by typing `exit` and re-enter it with 
+`docker start -ia deltachat` or `podman start -ia deltachat`.
+
+Within the container, install toolchains and build the native library:
+```
+deltachat@6012dcb974fe:/home/app$ scripts/install-toolchains.sh
+deltachat@6012dcb974fe:/home/app$ scripts/ndk-make.sh
+```
+
+Then, [build an APK](https://developer.android.com/studio/build/building-cmdline):
+```
+deltachat@6012dcb974fe:/home/app$ ./gradlew assembleDebug
+```
+
+### Troubleshooting
+
+- Executing `./gradlew assembleDebug` inside the container fails with `The SDK directory '/home/user/Android/Sdk' does not exist.`:
+
+  The problem is that Android Studio (outside the container) automatically creates a file `local.properties` with a content like `sdk.dir=/home/username/Android/Sdk`,
+  so, Gradle-inside-the-container looks for the Sdk at `/home/username/Android/Sdk`, where it can't find it.
+  You could:
+  - either: remove the file or just the line starting with `sdk.dir`
+  - or: run `./gradlew assembleDebug` from outside the container (however, there may be incompatibility issues if different versions are installed inside and outside the container)
+
+- Running the image fails with `ERRO[0000] The storage 'driver' option must be set in /etc/containers/storage.conf, guarantee proper operation.`:
+
+  In /etc/containers/storage.conf, replace the line: `driver = ""` with: `driver = "overlay"`.
+  You can also set the `driver` option to something else, you just need to set it to _something_.
+  [Read about possible options here](https://github.com/containers/storage/blob/master/docs/containers-storage.conf.5.md#storage-table).
+
+## <a name="setup-podman"></a>Setup Podman
+
+These instructions were only tested on a Manjaro machine so far. If anything doesn't work, please open an issue.
+
+First, [Install Podman](https://podman.io/getting-started/installation).
+
+Then, if you want to run Podman without root, run:
+```
+sudo touch /etc/subgid
+sudo touch /etc/subuid
+sudo usermod --add-subuids 165536-231072 --add-subgids 165536-231072 yourusername
+```
+(replace `yourusername` with your username).
+See https://wiki.archlinux.org/index.php/Podman#Rootless_Podman for more information.
+
+## <a name="install-build-environment"></a>Install Build Environment (without Docker or Podman)
+
+To setup build environment manually:
+- _Either_, in Android Studio, go to "Tools / SDK Manager / SDK Tools", enable "Show Package Details",
+  select "CMake" and the desired NDK (install the same NDK version as the [Dockerfile](https://github.com/deltachat/deltachat-android/blob/master/Dockerfile)), hit "Apply".
+- _Or_ read [Dockerfile](https://github.com/deltachat/deltachat-android/blob/master/Dockerfile) and mimic what it does.
+
+Then, in both cases, install Rust using [rustup](https://rustup.rs/)
+and Rust toolchains for cross-compilation by executing `scripts/install-toolchains.sh`.
+
+Then, configure `ANDROID_NDK_ROOT` environment variable to point to the Android NDK
+installation directory e.g. by adding this to your `.bashrc`:
+
+```bash
+export ANDROID_NDK_ROOT=${HOME}/Android/Sdk/ndk/[version] # (or wherever your NDK is) Note that there is no `/` at the end!
+export PATH=${PATH}:${ANDROID_NDK_ROOT}/toolchains/llvm/prebuilt/linux-x86_64/bin/:${ANDROID_NDK_ROOT}
+```
+
+After that, call `scripts/ndk-make.sh` in the root directory to build core-rust.
+Afterwards run the project in Android Studio. The project requires API 25.
+
+With chance, that's it :) - if not, read on how to set up a proper development
+environment.
+
+
+## Install Development Environment
+
+1. Some libs required by Android Studio may be missing on 64 bit Linux machines
+   [Source](https://developer.android.com/studio/install.html)], so for Ubuntu execute
+   `$ sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386 lib32z1 libbz2-1.0:i386`
+   and for Fedora execute
+   `$ sudo yum install zlib.i686 ncurses-libs.i686 bzip2-libs.i686`.
+
+2. Download Android Studio from <https://developer.android.com> (android-studio-ide-...-linux.zip)
+   and unpack the archive which contains a single folder called `android-studio`;
+   move this folder e.g. to `~/android-studio`.
+
+3. To launch Android Studio for the first time, open a terminal, navigate to
+   `~/android-studio/bin`, execute `./studio.sh` and use all the standard values
+   from the wizard.
+
+4. Android Studio now asks you if you want to open an existing project;
+   choose `~/deltachat-android` as created in the "Build" chapter (Android Studio starts to
+   build the project, however, there are some steps missing before this will
+   succeed).
+
+5. If components are missing, click on the corresponding error
+   message and install eg. required SDKs and the "Build-Tools" (you should
+   also find the option at "Tools / Android / SDK Manager / SDK Platforms").
+   Now the build should succeed - but the app still misses the native part.
+
+6. Download Android NDK from
+   [NDK Archives](https://developer.android.com/ndk/downloads)
+   and extract the archive containing a single folder
+   called something like `android-ndk-r23b-linux`; move this folder e.g. to `~/android-ndk`.
+
+7. Export the folder path to your environment as `ANDROID_NDK_ROOT` and add it to `PATH`.
+   You can achieve this e.g. by adding this to your `.bashrc`
+   ```bash
+   export ANDROID_NDK_ROOT=${HOME}/android-ndk
+   export PATH=${PATH}:${ANDROID_NDK_ROOT}/toolchains/llvm/prebuilt/linux-x86_64/bin/:${ANDROID_NDK_ROOT}
+   ```
+
+## Run UI Tests and Benchmarks
+
+- You don't necessarily need a dedicated testing device.
+  Backup your current account first, maybe there are some bugs in switching accounts.
+
+- You can run benchmarks on either an emulated device or a real device.
+  You need at least Android 9. For better benchmark results,
+  you should run the benchmark on a real device and make sure that the core is compiled in release mode.
+
+- Disable animations on your device, otherwise the test may fail:
+  at "Developer options"
+  set all of "Window animation scale", "Transition animation scale" and "Animator duration scale" to 0x
+
+- In Android Studio: "File" / "Sync project with gradle files"
+
+- In Android Studio: "Run" / "Edit configurations" / "+" / "Android Instrumented test":
+  Either select a specific class or select "All in Module" / "OK" /
+  Select your configuration in the toolbar / Click on the green "run" button in the toolbar to run the tests
+
+### Get the benchmark results
+
+When the benchmark is done, you will get a result like
+`MEASURED RESULTS (Benchmark) - Going thorough all 10 chats: 11635,11207,11363,11352,11279,11183,11137,11145,11032,11057`.
+You can paste `11635,11207,11363,11352,11279,11183,11137,11145,11032,11057`
+into a cell in a LibreOffice spreadsheet, do "Data" / "Text to columns",
+choose `,` as a separator, hit "OK", and create a diagram.
+
+### Run online tests
+
+For some tests, you need to provide the credentials to an actual email account.
+You have 2 ways to do this:
+
+1. (Recommended): Put them into the file ~/.gradle/gradle.properties (create it if it doesn't exist):
+   ```
+   TEST_ADDR=youraccount@yourdomain.org
+   TEST_MAIL_PW=youpassword
+   ```
+
+2. Or set them via environment variables.
+
+## Decoding Symbols in Crash Reports
+
+```
+$ANDROID_NDK_ROOT/ndk-stack --sym obj/local/armeabi-v7a --dump crash.txt > decoded.txt
+```
+
+`obj/local/armeabi-v7a` is the extracted path from `deltachat-gplay-release-X.X.X.apk-symbols.zip` file from https://download.delta.chat/android/symbols/
+
+Replace `armeabi-v7a` by the correct architecture the logs come from (can be guessed by trial and error)

+ArcaneChat — децентрализованный и защищённый мессенджер, удобный для друзей и семьи.
+
+• Анонимность. Мгновенный вход без номера телефона, e-mail или других личных данных.
+
+• Гибкость. Поддерживает несколько профилей чатов и легко настраивается на нескольких устройствах.
+
+• Расширяемость. В чатах можно использовать мини-приложения: списки покупок, календари или игры.
+
+• Надёжность. Работает даже при плохом соединении и в сложных сетевых условиях.
+
+• Безопасность. Проверенное сквозное шифрование, защищённое от сетевых и серверных атак.
+
+• Самостоятельность. Может работать с вашим собственным e-mail-адресом или сервером.
+
+ArcaneChat — клиент Delta Chat, разработанный с акцентом на удобство, качественный UX и экономию трафика. Также приложение часто экспериментирует с новыми функциями, которые со временем могут быть добавлены в официальный клиент Delta Chat.
+
+<b>Основные отличия от официального клиента Delta Chat:</b>
+
+<ul>
+<li>Поддержка некоторых стилей markdown в текстовых сообщениях (жирный, курсив, зачёркнутый и т.д.)</li>
+<li>Поддержка отображения анимированных стикеров Telegram (.tgs-файлы)</li>
+<li>Поддержка предпросмотра SVG-изображений</li>
+<li>Несколько цветовых тем/скинов</li>
+<li>Возможность отключать профили, полностью отключая им доступ в сеть для экономии трафика</li>
+<li>На панели переключения профилей видно состояние подключения каждого профиля</li>
+<li>Дополнительная опция для обмена местоположением на 12 часов</li>
+<li>Нажатие на сообщение с POI открывает его на карте</li>
+<li>Статус «был(а) в сети» отображается в списке контактов, как в WhatsApp, Telegram и т.д.</li>
+<li>Видео воспроизводятся по кругу — удобно для коротких GIF-видео</li>
+<li>У чата «Device Messages» в списке чатов отображается значок подтверждения</li>
+<li>В режиме «низкое качество» голосовые сообщения сжимаются сильнее для экономии трафика</li>
+<li>Автоматическая загрузка сообщений по умолчанию ограничена 640KB</li>
+<li>Отображаемое имя профиля всегда видно в заголовке приложения вместо названия приложения</li>
+<li>Для разработчиков мини-приложений: доступны дополнительные возможности WebXDC API, см. https://github.com/ArcaneChat/android/#webxdc</li>
+<li>Более удобная организация настроек с дополнительным разделом «Privacy»</li>
