The GitHub job's store is ~7.3 GiB but gc-max-store-size-linux is 6G, and nothing roots the devshells, so cache-nix-action's pre-save `nix store gc` deletes whichever paths cross the cap before every save. The snapshots land missing the JDK and the Android SDK components, so both `nix develop` steps re-download or rebuild them on every run. Raise the cap to 10G, which clears the store, and bump the key to nix-v3-. The first run after that downloads the full closure once and saves a complete snapshot; the gutted nix-v2- snapshots are not restored, so there is one cold run per ref and v3 is warm from then on. Compressed at ~0.47x its store the snapshot is ~4.7 GiB at worst, inside the 10 GB per-repo budget. What pushes the repo over that budget today is the four stale gradle- (v1) entries, which no restore-key can reach and which age out by LRU.
subtracks
subtracks is an open source Android client for Subsonic-compatible servers (Navidrome, gonic, LMS, Nextcloud Music and more). It is written natively in Kotlin and Jetpack Compose and gives you clean, convenient access to your music in the style of a modern media player.

Features
- Large Libraries: Built for very large libraries, from syncing the whole collection to playing playlists with thousands of tracks.
- Downloads: Song and bulk downloads, with download quality (encoding, bitrate) and metered-connection settings.
- Offline Mode: Stars, scrobbles and play counts queue up while you're offline and sync back to the server when you're online again.
- Artwork-first: Album and artist art everywhere, shown full-resolution in the detail and now playing views.
- Adaptive Theming: Colours drawn from the current song's artwork.
- Search: Fast search across the whole library, with per-list sort and filter controls.
- Playback: Gapless playback, an editable queue you can reorder and jump through, plus loop and shuffle modes.
- Up Next: Add items into the currently playing queue without rewriting it.
- Multiple Servers: Connect several servers and switch between them quickly.
- Stream Quality: Bitrate and format settings for Wi-Fi and mobile, with automatic switching.
- System Controls: Media notification and headset/Bluetooth controls.
Building
The project's entire toolchain is provided by a Nix flake. The default devshell provides JDK, Gradle and the Android SDK, so there is nothing to install by hand.
Therefore, to get started, you'll need to install Nix. I prefer Lix.
nix develop
gradle :app:assembleDebug
Test, lint and screenshot commands, plus the integration harness, are documented in AGENTS.md. The architecture is described in docs/architecture.md.
Contributing
The GitHub repository austinried/subtracks is a mirror of the repo hosted on my personal (private) code forge that syncs whenever I commit to it.
Bug reports and feature requests are accepted on GitHub, as well as pull requests, but:
- A well-crafted issue with clear reproduction and logs for bugs or mock-ups and use case details for features is preferred over a pull request
- Pull requests will be pulled in as patches to my code forge and then synced back (you'll still be the author, I'll be shown as the committer)

AI usage disclosure
This project contains code and documentation generated by LLM, which is created via human prompting, iteration and review. The current native rewrite is based on two (and a half) other iterations of this project that I coded by hand, so the architecture and other decisions behind that are all still coming from me.
