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! 🧪

We use ktlint with default rules:

# Check your code
./gradlew ktlintCheck

# Auto-fix issues
./gradlew ktlintFormat

• ✅ 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!

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

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!

# 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
