Rust clients for Navidrome/Subsonic, Jellyfin, Plex, Kodi and UPnP/DLNA. The Expo rocksky-engine module exposes connection, discovery, browsing and stream resolution through remoteLibrary. MPD is intentionally excluded.

Local music is the default library. Uploaded music remains available in the library selector. Saved servers can be selected, edited or disconnected there.

Connections #

Navidrome/Subsonic: server URL, username and password; salted Subsonic authentication.
Jellyfin: server URL, username and password; authentication exchanges the password for a token.
Plex: server URL and Plex token; supports selecting among music sections.
Kodi: scan for advertised HTTP servers via Zeroconf/mDNS, or enter the HTTP URL and configured username/password. Enable HTTP remote control and service announcements in Kodi. Discovery uses the advertised port and does not guess credentials.
UPnP/DLNA: discover media servers on the local network, or supply a device-description XML URL.

Credentials are encrypted with Android Keystore and stored in the app's no-backup directory. JavaScript receives public connection details and temporary media URLs. Persisted playback queues retain server/track IDs rather than these URLs. Disconnecting a source removes its connection, not any server content.

UPnP search filters loaded entries; Plex search operates inside a music section. Pagination loads more entries as needed. Play queues the currently loaded tracks.

Validation #

Always use release builds:

cargo test --release --locked --manifest-path native/libraries/Cargo.toml
bash scripts/build-android-test-release.sh

Run these commands from apps/app. The Android build script uses assembleRelease, and its native build uses cargo ndk build --release --locked. Protocol tests use local HTTP fixtures; actual server/device connectivity still requires testing against the user's servers on their network.

Client implementations were informed by the sibling music-player and rockbox-zig clients.
