DocVault is a modern Android document scanner and management application built with Kotlin and modern Android development practices.
The application provides an on-device workflow for capturing documents, extracting information using Google ML Kit, processing barcodes, and securely managing document files.
-
📷 Document Scanning
- Capture documents directly using the device camera.
- Handle camera permissions through Android's runtime permission system.
-
🔍 OCR & Text Recognition
- Extract text from captured documents using Google ML Kit OCR.
- Process document information directly on the device.
-
📊 Barcode Scanning
- Detect and process barcodes using Google ML Kit.
- Supports barcode-based document information extraction.
-
📁 Document Management
- Store and manage captured documents locally.
- Handle document URIs and application-owned files securely.
-
🔐 Secure File Handling
- Uses Android FileProvider for secure file sharing.
- Uses URI-based access rather than exposing direct filesystem paths.
-
💾 Backup Support
- Includes application-level backup support for stored app data.

DocVault follows modern Android development principles with an emphasis on maintainability, lifecycle awareness, and secure resource handling.
Key implementation areas include:
- Separation of application responsibilities
- Lifecycle-aware Android components
- Runtime permission handling
- Secure URI and file management
- On-device ML processing
- Camera integration
- Local document storage
- Application backup support
DocVault integrates the Android camera functionality to allow users to capture documents directly from the application.
Captured documents can be processed using Google ML Kit Text Recognition to extract text and document information without relying on a separate external OCR service.
Google ML Kit's barcode processing capabilities are used to detect and process supported barcodes from captured documents.
The application uses Android's FileProvider and URI management mechanisms to safely handle files and share them between application components without exposing raw filesystem paths.
