A lightweight HTTP server (based on NanoHTTPD) that streams local media files to Chromecast devices. It correctly handles HTTP Range requests for seeking, supports partial content responses, and can be easily extracted and reused in any Android app that needs to serve local files over HTTP. Demonstrates solid understanding of HTTP/1.1 protocol and file I/O.

A base RecyclerView adapter that provides common functionality for media file lists: multiple view types (headers, banners, items), item selection/deselection with checkboxes, integration with Glide preloader, and click listeners. This pattern can be reused in any Android app that displays lists with mixed view types and selection support, reducing boilerplate for similar screens.

A bounded priority queue implementation that keeps only the top N elements based on a comparator. Uses a min-heap internally to efficiently maintain the largest items. This is a classic data structure extracted cleanly, useful for any 'top K' ranking tasks (e.g., largest files, most used apps). Minimal dependencies and fully self-contained.

Parses LRC (LyRiCs) files with synced timestamps for karaoke-style display. Handles both synced and unsynced lyrics, metadata tags, and multiple encoding formats. Can be extracted and used in any music player app that wants to support LRC lyrics. The parsing logic is well-structured and independent of the rest of the audio player code.
