Refactor

[Aatricks]

This pull request introduces significant improvements to error handling, code structure, and content parsing logic across the application. The most notable changes include a comprehensive refactor of the HTML parsing logic for better manga/novel detection, systematic replacement of try/catch blocks with Kotlin’s runCatching for more concise error handling, and modularization of utility functions for improved readability and maintainability.

Error Handling Improvements:

• Replaced traditional try/catch blocks with runCatching in repository methods and throughout MainActivity, leading to more concise and idiomatic Kotlin error handling. (BaseRepository.kt, MainActivity.kt, ExploreRepository.kt, LibraryRepository.kt) [1] [2] [3] [4]

HTML Parsing and Content Extraction Enhancements:

• Refactored HtmlParser to modularize and clarify the logic for cleaning documents, parsing images and paragraphs, filtering out ads and irrelevant content, and merging paragraphs. Improved manga/novel detection logic to better distinguish between image-heavy and text-heavy content. (HtmlParser.kt) [1] [2]
• Added helper functions for merging paragraphs and determining when to merge or stop merging based on sentence structure. (HtmlParser.kt)

Code Structure and Readability:

• Extracted repeated logic into private helper functions (e.g., filterSources, mapFileTypeToContentType, buildMemoryCache, buildDiskCache) for improved maintainability. (ExploreRepository.kt, MainActivity.kt, EasyReaderApplication.kt) [1] [2] [3]
• Updated method signatures to explicitly declare Unit return types for clarity and consistency. (MainActivity.kt, LibraryRepository.kt) [1] [2]

Image Loader Configuration:

• Modularized the image loader setup in EasyReaderApplication by moving cache configuration into dedicated helper methods, improving clarity and flexibility. (EasyReaderApplication.kt)

Permissions and File Handling:

• Streamlined file permission checks and file type handling in MainActivity, using helper methods and more robust logic for determining permissions and supported file types. (MainActivity.kt)

These changes collectively improve the app’s robustness, readability, and maintainability, while also enhancing its ability to accurately parse and display both manga and novel content.
