Fifty-nine places put a raw Rust string into a field a person reads, and
the red toast drew it verbatim — a phone in a lift showed "could not reach
server: io: failed to lookup address information" under the password box.
One translator, src/mobile/trouble.js, called where an error is DRAWN
rather than where it is caught: the stores keep what Rust said and only
the sentence on screen is ours, so every sink is fixed at once. Five
screens that drew a failed read as an empty answer stop lying — Tracks no
longer reports a broken database as an empty library, a playlist that
could not be read is not an empty playlist, the lyrics face says a lookup
failed instead of "no lyrics" and finally carries the ⋯ that reaches Paste
lyrics, Gaps says why it could not reach the catalogue, and Search signed
out says so where it used to render nothing at all. The room list, which
is fire-and-forget over the wire, gets a twelve-second end and a Try
again.
rescan_library ran prune_missing() first, which deletes every track row
whose file does not exist — so one tap on You → Rescan library with the
folder unreachable emptied the whole index and returned Ok(()). It now
makes the root if it is merely not there yet and refuses if it cannot be
read, and You draws the path with what to do about it.
The mock grew a weather system so the walk can drive all of this: fail,
answer, offline and clear, checked before dispatch so a plugin command
arms like any other. Nine mock steps and one on the phone — the first
steps in thirty rounds that ever made a command reject or saw the client
signed out — and the last of them puts the weather away and leaves the app
as it found it.
One switch the desktop never needed, off by default: on mobile data every
Save the phone can start — a record, a track, a folder, a file, a
playlist's bulk, the now-playing Save — waits, with the reason on the bar;
streaming is never held back. The walk flips the switch, makes the
connection cellular and sees a download refused.
The same Tauri 2 project builds for Android: mobile.html as a third Vite
entry (src/mobile/, the mockup on real data), tauri.android.conf.json, the
mobile stubs (updater, lyric alignment, vocal separation), rustls reqwest
on Android, the AAudio buffer, and a hand-driven detour build
(src-tauri/android/{env,build,deploy,dev}.sh) while Developer Mode is off.
ANDROID.md is the recipe.
Playback: the media-session plugin crate (lock-screen card, MediaStyle
notification, audio focus, headset buttons, a foreground service that
promotes itself first — Android 14 kills the app otherwise), session
restore across reload and restart, solid chrome after measuring the
backdrop-filter lag.
The catalog: Search is the desktop's top bar (the top-result rule, artist
cards), the artist page and the record page are the desktop's, Home is the
desktop's landing page, Gaps per followed shelf. Playing goes through the
desktop's own source rules, moved verbatim from state.svelte.js into
src/lib/sources.js so both apps share one resolver; the phone readies the
next three tracks and crosses boundaries gapless. Save fetches a record or
a track into the library by the download rules; Transfers shows the
burst. The raw Soulseek search stays, offered on request, a peer's copy
streaming with the lane rising as the bytes arrive. Community is the
Soulseek side (rooms, chat, buddies); the private layer waits.
The opener and storage plugins (social links, the picked library folder,
all-files access), the volume normalization switch, and the harness:
tests/mobile/smoke.mjs walks the mock (a fake network behind
src/lib/events.js) and the real phone over CDP, perf.mjs measures frames.
