🛠️ Architecture

Core Components

🚀 GitHub Actions Build Process

Hexodus is configured with comprehensive GitHub Actions workflows that automatically build, test, and package the application when changes are pushed to the repository.

Build Workflow Features

• Automatic Building: Builds debug and release APKs on every push
• Unit Testing: Runs comprehensive unit tests with each build
• Multi-API Testing: Tests on multiple Android API levels (26, 28, 29, 30, 31, 33, 34)
• Artifact Upload: Automatically uploads built APKs as workflow artifacts
• Release Creation: Creates GitHub releases with signed APKs when tags are pushed

Workflow Configuration

The repository includes two main workflows:

1. Build Workflow (.github/workflows/build.yml):

   • Runs on every push and pull request
   • Builds debug and release APKs
   • Runs unit and instrumentation tests
   • Uploads APK artifacts

2. Release Workflow (.github/workflows/release.yml):

   • Triggers when a new tag is pushed
   • Creates a GitHub release
   • Builds and signs release APK
   • Uploads APK to release assets

Building Locally

To build the project locally, ensure you have the Android SDK and build tools installed, then run:

./gradlew assembleDebug

or for a release build:

./gradlew assembleRelease

The APK files will be generated in app/build/outputs/apk/.

Continuous Integration

The CI/CD pipeline ensures:

• Code quality through automated testing
• Compatibility across different Android versions
• Proper APK signing for releases
• Automatic documentation of changes

1. ThemeCompiler: Compiles hex colors into overlay APK structures in memory
2. ShizukuBridgeService: Proxies overlay commands through trusted shell processes
3. MonetOverrideService: Spoofs the system's color palette generation
4. HighContrastInjectorService: Generates signed APKs mimicking Samsung's High Contrast themes
5. FoldableDisplayService: Handles dual-display contexts for Z Flip 5
