The phone has been wearing tauri's logo. `tauri android init` writes the
generated project's `res/` from its own template and never reads
`src-tauri/icons/android/`, which has carried the falcon since 50afa6a, and the
detour build runs cargo and Gradle directly — so nothing ever copied it across:
the two dominant colours in the packaged `mipmap-xxxhdpi/ic_launcher.png` are
`#24c8db` and `#ffc131`, tauri's own brand cyan and amber. `src-tauri/android/res/`
is the app module's res now, tracked, and `build.sh` and `dev.sh` copy the whole
tree into `gen/android` before Gradle, because that project is regenerated and
gitignored and an asset that only lives there is an asset that disappears.
It is a real adaptive icon: the kit's foreground and its **monochrome** layer at
five densities, the legacy mipmaps under it, and the background as one
`#FF05080B` colour resource rather than five identical flat PNGs, so the gradient
being mocked separately replaces one file. The kit's own XML could not ship — it
points every layer at `@drawable/` while shipping them as PNGs under `mipmap-*`,
and in the generated project two of those three references resolve to Android
Studio's template robot rather than failing — so the overlay's XML says
`@mipmap/` and `@color/`, and its colour file takes the same name tauri's does,
because two files declaring one colour is a hard aapt2 error.
Losing the copy would be silent — the APK still builds, still installs, and wears
the old logo with nothing in the log — so `verify-icon.sh` opens every APK both
scripts make and reads the resources back out: the two `mipmap-anydpi-v26` XMLs
present, and four PNG names at five densities byte for byte from the overlay. A
release APK keeps neither the bytes nor the names — AGP re-encodes every PNG and
shortens every resource path — so that path asks `aapt2 dump resources` what each
name points at and compares pixel dimensions instead; 72×72 at hdpi still tells
the kit's icon from tauri's 49×49. No walk step: a launcher icon is not reachable
from inside the app, and the masking and the themed layer want a minute with the
phone's home screen.
Every APK this port has produced is `assembleArm64Debug`, and the generated
project turns R8 on for `release` and only for `release` — while tauri finds a
plugin class by string, files every `@Command` under `commands[method.name]`,
and lets Jackson fill every `@InvokeArg` field by field. Minification breaks
exactly that, and it breaks it without a word: the app compiles, installs,
launches, shows Home, and then a tap on Library folder answers "No command
pickFolder found for plugin ..." in logcat and nothing on screen. So each
plugin module now carries its own `consumer-rules.pro` naming its own
reflected surface — the shape tauri-android and tauri-plugin-dialog already
use in this build, and one that travels with the plugin into a regenerated
`gen/android`, which a rule written into that gitignored tree would not.
What belongs to no single plugin is in `src-tauri/android/proguard-soulstream.pro`,
copied into the generated project by the build script because the app's own
Gradle file is regenerated: the runtime annotation attributes, a `-dontwarn`
pair for the two `java.beans` classes jackson-databind references and Android
does not have (R8 turns a missing class into a build error, so without them
there may be no APK at all), and a keep for the four `@Command` methods
declared on `app.tauri.plugin.Plugin` itself. Tauri's own rule matches classes
annotated `@TauriPlugin` and the members they declare; the base class carries
no such annotation, so nothing names `registerListener` — which is what the
lock-screen card's buttons and the download notice's Cancel and Open ride on.
`build.sh` grows `--release`: the release profile, `--features tauri/devtools`
so the walk can still attach at all, `assembleArm64Release`, and a zipalign and
sign with the same debug key the phone already trusts, so the APK installs over
the app rather than forcing an uninstall that would take Kyle's settings with
it. With no argument the script is what it has always been, cargo line for
cargo line, so deploy.sh and ship.sh keep the path they run every twenty
minutes. And it has been built. Not on the phone and not as arm64 — as **x86_64**, on an
emulator, because that is what this machine can run — but the flavour is the
only difference: the same Gradle, the same R8, the same rules, the same
zipalign and apksigner. `minifyX86_64ReleaseWithR8` succeeded and wrote **no**
`missing_rules.txt` at all, which is the `-dontwarn` pair doing its job;
`lintVitalX86_64Release` passed, so the `-x lintVital` advice is for a failure
that has not happened. The signed APK went over the debug app with
`adb install -r` and left its data alone, exactly as the same-key argument
above says it must.
Then the minified app was walked: Home, the record, playback, the queue, the
sheets, the lyrics, the drags, the export — **131 of 131, no exceptions, no
console errors, every step as expected**, and nothing in logcat about a missing
command or class. That is the failure this round exists to prevent, looked for
and not found.
What it does not cover is the hands-only list in ANDROID.md — the pickers, the
notification buttons, the share sheet — which no walk reaches, and the four
`@Command` methods on `Plugin` itself remain a precaution rather than a
diagnosed bug. The document says so, command by command.
Everything written this session that has not been through the device: rounds 43
to 48 (each patch adversarially verified, 43's transient-notice expectation
fixed), a partial round 49, the pipeline scripts, the Android Auto design and
the icon comparison mock. Also the two harness changes that were never A/B'd —
adaptive waits, which may only shorten a declared wait and never lengthen it,
and a ship that runs the mock walk and the deploy at the same time. The A/B and
its 255-step baseline are in handoff/tools; main stays at what the phone has
actually walked.
Without a drag: a playlist row's sheet moves it up, down or to the top and
persists the whole order in one call (playlist_set_order, as the desktop's
drop does); a queue row's sheet moves it up or down, never past the track
playing. Also src-tauri/android/ship.sh — one round end to end: the mock
walk, the embedded build installed, the phone walk, the commit, each step
gated on the one before.
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.
