This repository is a collection of technical knowledge and solutions focused on mobile application development, particularly for Android and iOS platforms. It covers a wide range of practical engineering challenges, including hotfix and patching techniques, database management and repair, network communication, logging, and video processing. The content is presented as shared knowledge, documenting real-world problems and their implementations.
The project provides detailed guidance on applying hotfixes to running Android applications through multiple methods, such as class replacement, full Dex replacement, and native method patching. It also addresses the complexities of database operations, offering solutions for ORM mapping, concurrent read-write access, data recovery from corruption, and performance optimization. Network programming topics include handling IPv6-only networks, implementing high-availability communication, and establishing encrypted sessions using protocols based on TLS 1.3.
Additional areas covered include cross-platform network library construction, hardware and software video encoding with frame manipulation, and efficient logging systems that use memory-mapped I/O and per-line compression. The documentation also explores security measures like database encryption with SQLCipher, server identity authentication, and replay attack prevention.
