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.
This is an Android application that turns a smartphone into an SMS/MMS gateway. It exposes a local REST API (Ktor-based HTTP server) for sending and receiving messages, supports cloud server integration via Firebase and Server-Sent Events, and provides webhook delivery, end-to-end encryption (RSA-OAEP + AES-GCM), and device key rotation. The architecture is modular: foreground services (SSE, ping, local server), WorkManager workers for background tasks (message sending, webhook queue processing, inbox upload, settings sync), a Room database for persistence, and Koin for dependency injection. The codebase is well-structured with event-driven communication via a custom EventBus, a validated state machine for message lifecycle, encrypted storage, and rich UI fragments. It supports SMS, MMS, and data SMS, with inbound message capture via broadcast receivers and content observers.
The AN2Linux Client is an Android application designed to forward device notifications to a Linux desktop companion server over secure TLS connections. It intercepts notifications via Android's NotificationListenerService, applies user-configured filters (per-app and global), and transmits notification data to configured servers (Wi-Fi, mobile, or Bluetooth) using certificate-based authentication. The architecture combines Android components (Activities, Services, BroadcastReceivers) with modern patterns like ViewModels/LiveData for UI state management, custom preferences for advanced settings, and isolated cryptographic helpers for TLS operations. Key features include foreground service execution to bypass background restrictions, boot-time auto-start, granular notification filtering, and support for multiple connection types with SSID whitelisting for Wi-Fi.
