Prerequisites

Before you dive in, make sure you have these tools ready:

☐ Android Studio (Latest stable version)
☐ Android SDK (API 21+)
☐ Android NDK (for native code compilation)
☐ CMake (for building native modules)
☐ SWIG (for generating JNI bindings)
☐ Git (obviously!)

Quick Start

# Clone the repository
git clone https://github.com/Windscribe/Android-App.git
cd androidapp
# Build debug version
./gradlew assembleDebug
# Or open in Android Studio and hit Run! 🎯

🎯 StrongSwan Setup

Prebuilt binaries are included, but if you're feeling adventurous:

1. Follow the official StrongSwan Android build guide
2. Replace contents in ./strongswan/libs
3. Test thoroughly before committing! 🧪

---

💻 Code Style

Kotlin (Preferred) ✨

We use ktlint with default rules:

# Check your code
./gradlew ktlintCheck
# Auto-fix issues
./gradlew ktlintFormat

General Guidelines

• ✅ Use Kotlin for all new code
• ✅ Prefer coroutines over callbacks
• ✅ Use Kotlin flows for reactive streams
• ✅ Follow MVP pattern
• ✅ Write meaningful commit messages
• ✅ Test your changes!

---

🤝 Contributing

We ❤️ contributions! Here's how to get started:

The Golden Rules

1. Code Style is Sacred

• Run ktlintFormat before committing
• Follow existing patterns
• Keep it clean and readable

2. Kotlin First, Always

• The app modules (base/mobile/tv) are 100% Kotlin — keep them that way
• New code MUST be in Kotlin (no new Java files)
• Use coroutines and flows

3. Respect the Module Hierarchy

   Feature Modules → base → UI Modules
   

   NO CIRCULAR DEPENDENCIES! 🚫

4. Test Your Changes

• Write unit tests for business logic
• Add instrumented tests for UI
• Manual testing is also important!

Development Workflow

# 1. Create a feature branch
git checkout -b feature/awesome-new-feature
# 2. Make your changes# ... code code code ...# 3. Format and lint
./gradlew ktlintFormat
# 4. Run tests
./gradlew test# 5. Commit with meaningful message
git commit -m "feat: add awesome new feature"# 6. Push and create PR
git push origin feature/awesome-new-feature

For detailed development workflows, see SKILL.md

🔢 Versioning

Format: [major].[minor].[build]

Example: 3.72.123

• 3 = Major version
• 72 = Minor version
• 123 = Build number
