This repository is a robust Android library designed for debugging applications by providing a user-friendly interface to view system logs (logcat). It functions as a standalone framework that integrates into an Android app via Gradle dependency. The core functionality involves capturing logs from the system logcat process, parsing them using regex patterns, filtering them based on user-defined rules (TAG, level, search keywords), and displaying them in a RecyclerView with features like auto-merging, highlighting, and saving to file. The architecture relies on a ContentProvider for automatic initialization, a Foreground Service to maintain the log capture process (handling Android 8+ and 14+ restrictions), and a Floating Window/Notification for user interaction. The code demonstrates strong engineering practices, particularly in handling Android version fragmentation (e.g., specific handling for Android 12's Foreground Service restrictions and Android 14's targetSdk 34 requirements). It includes OOM protection mechanisms by limiting the number of displayed logs and uses MD5 hashing to prevent duplicate log entries when restarting the capture stream.
CheatReader is a Flutter-based desktop ebook reader designed for low-distraction reading. It provides a floating, always-on-top window that supports single-line and multi-line reading modes, transparency, a boss key for quick hide/restore, system tray integration, and app disguise (icon/name change). The application imports local files in multiple formats (txt, epub, html, md, fb2, docx, pdf) via text extraction, never modifying the source. It features a bookshelf with reading progress tracking, customizable keyboard shortcuts, auto page-turn, full-text search, and a control panel for all settings. The architecture is a standard Flutter app with platform-specific abstractions for window management, file import, and startup behavior, targeting Windows, macOS, and Linux. The codebase is well-tested, localized in English and Chinese, and uses a spec-driven development process (OpenSpec). While the main reader surface widget is large (~2600 lines), the overall structure demonstrates solid engineering with reusable patterns for platform abstraction, settings persistence, and text extraction.
