The Obtainium Emulation Pack is a curated collection of Android app configurations for the Obtainium updater tool, focused on emulation, frontend utilities, and related tools. It processes a sparse JSON definition file (src/applications.json) through a pipeline of Python scripts to generate two variant-specific JSON files (standard and dual-screen) that users import into Obtainium for automatic app updates. The architecture centers around a Justfile task runner orchestrating validation, normalization, documentation generation, and minification scripts. Key features include sparse settings storage (only non-default values), variant inclusion flags for dual-screen compatibility, automated live testing of update sources, and scheduled CI workflows that detect and report breakages via GitHub issues. The system emphasizes ease of setup: install Obtainium, import the JSON, and receive updates for over 100 curated apps.
