A lightweight, event-driven XML streaming framework (LWXML) that provides a full pipeline of readers, writers, filters, and translators. It is cleanly abstracted with interfaces for reading/writing XML events and supports composition (tee, filter, pushback). This framework is used internally for ODF document conversion but is entirely self-contained and could be reused in any Java project needing efficient, streaming XML processing without DOM overhead.

A complete converter from SVM (StarView Metafile) format to SVG. It parses binary SVM actions and translates each into corresponding SVG elements via a pluggable translator pattern. The code is well-structured, with separate translators for different action types (text, polygons, colors, etc.) and handles complex state management (color, font, map mode). This is a standalone conversion library that could be extracted for any project requiring SVM/SVG rendering.

A utility class for reading and writing files with built-in per-file locking and a read cache. It provides methods for readObject/writeObject (serialization), readString/writeString, and readBytes/writeBytes, all with optional synchronization. The design is simple and robust, making it easy to reuse for any Android (or Java) project that needs thread-safe file persistence with caching.

A utility class for converting between density-independent pixels (dp), scaled pixels (sp), and raw pixels, as well as detecting screen size and e-ink displays. It encapsulates all Android display metrics in one place and provides reusable static methods. This is a common pattern in Android apps, but the implementation here is clean, well-documented, and easily extractable.
