A modern Android document scanning application built with Jetpack Compose that uses ML Kit for optical character recognition (OCR) and document classification.

• Document Scanning: Capture documents using the device camera
• OCR Text Extraction: Extract text from scanned documents using Google ML Kit
• Document Classification: Automatically classify documents into categories:
  • Receipts
  • ID Cards
  • Prescriptions
  • Contracts
  • Event Posters
  • Invoices
  • Other documents
• Document Management: Store, search, and manage scanned documents
• Modern UI: Built with Jetpack Compose and Material 3 design

• Language: Kotlin
• UI Framework: Jetpack Compose
• Architecture: MVVM with Repository pattern
• Dependency Injection: Hilt
• Database: Room
• Camera: CameraX
• OCR: Google ML Kit Text Recognition
• Navigation: Navigation Compose
• Async: Kotlin Coroutines & Flow

• Android API 24+ (Android 7.0)
• Camera permission
• Internet permission (for ML Kit)

1. Clone the repository
2. Open in Android Studio
3. Sync project with Gradle files
4. Run the app on a device or emulator with camera support

The app requires the following permissions:

• CAMERA - For document scanning
• INTERNET - For ML Kit functionality
• READ_EXTERNAL_STORAGE - For accessing stored images
• WRITE_EXTERNAL_STORAGE - For saving captured images (API 28 and below)

The app follows Clean Architecture principles with:

• UI Layer: Compose screens and ViewModels
• Domain Layer: Use cases and business logic
• Data Layer: Repository, Room database, and ML Kit services

• CameraScreen: Document capture interface
• HomeScreen: Document list and search
• DocumentDetailScreen: View document details
• OCRService: Text extraction using ML Kit
• DocumentClassificationService: Document type classification
• DocumentProcessingService: Orchestrates OCR and classification
