Overall Project:
This project involved developing a specialized Android application designed to assist aviation engineers in troubleshooting aircraft systems. The app offers a comprehensive suite of features, including quizzes, assessments, API integration, document viewing, and robust security measures.
Specific Features:
- Quizzes and Assessments: The app provides a platform for engineers to test their knowledge through various quizzes and assessments.
- API Integration: The app connects to external APIs to fetch real-time data, updates, and information relevant to aircraft systems.
- Document Viewing: Users can access and view PDF documents, including technical manuals, maintenance records, and aircraft schematics.
- Search Functionality: The app offers a powerful search feature that allows users to search for specific keywords or phrases within documents.
- Download Management: Users can download PDF documents for offline viewing.
- PDF Protection: The app implements measures to prevent unauthorized screenshots or recordings of sensitive PDF content.
Technical Implementation:
- MVVM Architecture: The app follows the Model-View-ViewModel architectural pattern for better separation of concerns and maintainability.
- Kotlin: The primary programming language used for development.
- Coroutines: Asynchronous programming is handled using Kotlin coroutines for non-blocking operations.
- Room: A local database is used to store app data, such as quiz results and downloaded documents.
- DI with Dagger Hilt: Dependency injection is implemented using Dagger Hilt for efficient dependency management.
- Custom Views: Custom views are created to provide a tailored user experience.
- Lifecycle Aware Components: The app leverages Android’s lifecycle aware components to manage the app’s lifecycle and prevent memory leaks.
- Retrofit: A type-safe HTTP client is used for network requests to APIs.
- Threading: Background tasks and network operations are handled using threads or coroutines.
- Third-Party Libraries: Various third-party libraries are used for specific features, such as PDF viewing, image loading, and analytics.
Additional Considerations:
- Security: Robust security measures are in place to protect sensitive aviation data, including encryption and authentication.
- Offline Functionality: The app allows users to access downloaded documents and certain features even when offline.
- Performance Optimization: The app is optimized for performance to ensure a smooth user experience, especially when handling large PDF files.
- Accessibility: The app is designed to be accessible to users with disabilities, adhering to accessibility guidelines.
