A generic, thread-safe cache implementation with configurable maximum size, time-based expiration, and pluggable eviction policies via CacheFullRemoveType. It provides hit/miss tracking, serialization support, and a Map-like interface. This component is self-contained and can be extracted into any Java/Android project needing a customizable in-memory cache.

Extends SimpleCache with asynchronous data fetching and preloading capabilities. It supports forward/backward preloading based on a key list, network type restrictions, and a listener pattern for data retrieval. The use of CountDownLatch for synchronous waiting and a dedicated thread pool makes it a reusable pattern for any list-based data loading scenario.

A two-level image cache combining ImageMemoryCache (in-memory) and ImageSDCardCache (disk). It handles image fetching, decoding with optional downsampling, and provides callbacks for UI updates. The architecture separates concerns cleanly and can be reused as a reference for implementing multi-tier caching in Android apps.

A custom ListView that supports pull-to-refresh and automatic load-more when scrolling to the bottom. It includes header/footer animations, configurable text, and listener interfaces. This is a self-contained widget that can be extracted and used in any Android project needing these features without external libraries.

A comprehensive file utility class providing read/write operations, file manipulation (move, copy, delete), path parsing, and directory creation. It handles edge cases like null inputs and missing files gracefully. This utility is reusable across any Java/Android project and demonstrates robust error handling and input validation.
