android auto: the covers, and the grid a record is owed
Round fifty put the tree in the car with every row a bare line of text. This
gives the rows their sleeves and asks for albums to be drawn as a grid — the
two things the design picked that a tree alone cannot express, and the only
parts of a car screen the app actually controls.
**Artwork goes out as a `content://`, not as bytes.** media3 will carry a cover
as data in the metadata and the legacy stub Android Auto binds turns that into
a bitmap per row — inside a single Binder reply with a one-megabyte ceiling for
the whole list. Two hundred rows of even thumbnailed JPEG is a
`TransactionTooLargeException` on a list that worked yesterday. A URI is a few
dozen bytes and the host fetches only what it draws. The provider stays
`exported="false"`; each browse grants read on its own URIs to the package that
asked, which `onGetChildren` already knows.
Reaching the library needed a new `file_paths.xml` in the res overlay, and it
needs BOTH spellings of one directory. Covers live under the app's DATA dir,
which `files-path` cannot reach — that tag means `getFilesDir()`, the `files/`
subdirectory. `root-path` can, but FileProvider resolves a file through
`getCanonicalPath()` before matching, and for the primary user
`/data/user/0/<pkg>` canonicalises to `/data/data/<pkg>`, so a root scoped to
`/data/user/` never matches on a phone. `/data/user/` still earns its place:
a car's driver profile is user 10 and does not canonicalise away.
The grid is `CONTENT_STYLE_BROWSABLE_HINT` on the parent's `LibraryParams` —
grid for `ss:albums` and for an artist's albums, list for artists and tracks.
Those keys belong to the host rather than to media3, which is why the same
constants serve a phone-projected car and a head unit alike.
**Three failures, one cause: a catch with nothing in it.** `artUri` returned
null on any throw and said nothing, and every row came back coverless with the
database, the res overlay and the APK all checking out — the binary XML was
dumped out of the APK to prove the root was in there. It cost an afternoon and
two wrong diagnoses. One `Log.w` in the catch named both real bugs in a single
run: `JSONObject.optString` returns the four-character string `"null"` for a
JSON null rather than `""`, so the tabs were handing `File("null")` to the
provider (`isNull` is checked first now); and the canonical-path substitution
above, which is visible ONLY in that exception's text — `readlink -f` on the
device does not show it, and believing it cost the first wrong answer. The
warning latches to one line per process, because two hundred identical traces
would bury the tree logging it sits beside.
The prober reports each row's `iconUri` now. A tree walk could say a row
arrived but never whether it would be drawn with anything, which is the one
thing this round changes, and `art:""` against a real `content://` is the whole
difference.
Verified on the Pixel 6a through Android Auto's own binder with the app cold:
both albums come back carrying
`content://com.soulstream.app.fileprovider/ss_library_canonical/...cover.jpg`.
The car screen itself is still the Desktop Head Unit's to show.

android: the same SIGPIPE race, in the two focus checks it has not lost yet
deploy.sh and dev.sh both ask which app is on screen with `echo "$FOCUS" | grep -qi`, under the same `set -o pipefail`. $FOCUS is one line, so echo has always finished writing before grep -q exits and the race has never been lost — but it is the identical shape that made verify-icon.sh report a missing file in an APK that contained it. Herestrings, so there is no writer to kill. |

android: the icon gate answered fail / pass / fail to the same APK
Round 44's verify-icon.sh had never run inside deploy.sh — only by hand — and it does two things there that it cannot do standalone. deploy.sh exports MSYS_NO_PATHCONV=1 for its adb calls, and that switch is global, so the APK path reached aapt2 as /f/Coding/... Windows binaries cannot open an MSYS path, and aapt2's answer is "failed opening zip: I/O error", which reads exactly like a corrupt APK rather than like a path. The four aapt2 calls now get cygpath -w explicitly; unzip and cmp keep the MSYS form, because they want that one. The second is worse, because it is intermittent. Every membership test was `echo "$VAR" | grep -q PATTERN`, under the `set -o pipefail` at the top. grep -q exits the moment it matches; echo is still pushing 70 KB of unzip listing into a pipe that just closed, takes SIGPIPE, exits 141 — and pipefail promotes the writer's status to the pipeline, so a check that FOUND what it was looking for reports failure. Whether it fires depends on where the match falls in the stream, so three runs against one unchanged APK gave fail, pass, fail, each naming a different missing file. Six of those, now herestrings: no writer process, nothing to kill. Eight runs green afterwards. Worth saying plainly: the APK was correct the entire time. The gate was wrong, and a gate that is green at random is worse than no gate, because the failure it invents points at the build. |

android: the launcher's ground is the desktop's, not a flat colour under it
The icon round left the adaptive background as one `#FF05080B` and a note that a gradient was being mocked. The mock settles it: the falcon covers about a quarter of a circle-masked tile, so the ground is three quarters of what anyone sees, and concept 04's glow survives every mask — the visible top-left corner goes from `#05080B` to `#0E3543`. So `@color/ic_launcher_background` becomes `@drawable/ic_launcher_ground`, a vector carrying the desktop icon's own linear surface and the radial glow over it, every number `src-tauri/icons/icon.svg`'s multiplied by 108/1024 and nothing else. The colour resource stays where it is, unreferenced, because its filename is the only thing stopping tauri's own `#fff` from colliding with it. A vector and not five PNGs on evidence. The kit's glow has a uniform scale, so the SVG ellipse is a circle and its rotation is a no-op, which is exactly what `android:type="radial"` can carry; two numbers there and no vector could have said it. The linear axis is 51.1° off horizontal, which rules out a `<layer-list>` of shapes as well, whose angle must be a multiple of 45. It was compiled and linked with the SDK's own aapt2 over the real merged res tree and every stop read back out of the APK. The name is `ic_launcher_ground` and not `ic_launcher_background` on purpose: the generated project still carries Android Studio's template drawable of that name, so under the other name an overlay copy that failed would silently link the green robot — under this one it is a hard link error, which was tested too. `verify-icon.sh` follows the layer. It does not ask whether the file is in the APK; it asks what the adaptive icon's `<background>` resolves to, through the resource table, in both build types, and then reads concept 04's six stops back out of what it found — which catches a stale APK as well as a lost overlay. Passing on a debug APK and on one put through `--shorten-resource-paths`, failing on a stale one, and saying NOT CHECKED rather than guessing when aapt2 is absent. What none of it can see is a pixel: banding on the OLED, the glow's weight under the Pixel's mask and how the falcon reads on a lit ground are a launcher screenshot on the phone, and ANDROID.md says so instead of implying the check covers it. One slot the ground reaches is not the launcher at all. `MediaHub.appIcon()` draws whatever `getApplicationIcon()` returns into a 512 px bitmap and hands it to the lock-screen card as the large icon for any track whose cover has not been decoded yet, so the card and the shade carry this ground as well — the quickest place for Kyle to look at it, and the only reader of the launcher icon inside the app. The walk reads that card's title and the session's playback state and never its icon, so no step changes meaning. The Android 12+ splash very likely changes as well, and the other way from what the docs' one-line version of the rule suggests: the platform drops an adaptive background only when it is a single colour close to `windowSplashScreenBackground`, which round 44's flat `#05080B` was, so the falcon has been drawing there alone and enlarged; a gradient is not one colour, so it is kept and the whole icon is drawn. Likely, not proven — that one is a screenshot too. |

android: the icon where it moves — the glyph, the lock screen and a splash that is not white
Both notification glyphs are the same falcon now, the logo kit's monochrome path verbatim inside a group that re-frames it for a 24dp box — the playback card's and the transfers notice's, because a note beside an arrow does not read as one app, and the transfers one keeps the tray bar it always had so the falcon dives into it. The fill stays white on transparent: the shade composites a small icon from its alpha channel alone and tints it itself, so a coloured export would arrive as a white blob. The lock screen falls back to the app's own icon instead of a grey hole. `MediaHub.art` is null from the moment a track changes until the frontend has finished decoding its cover, and null forever for a track with none, so `appIcon()` decodes the launcher icon ONCE — through the PackageManager, because a library module's R has no `ic_launcher` — and hands it to both the card and `METADATA_KEY_ALBUM_ART`. The app manifest lives in gitignored `gen/` and declares no category, so the media-session plugin's own library manifest contributes `android:appCategory="audio"` through the merger, and a `Theme.App.Starting` on the brand ground replaces Android 12+'s white flash — in `values-v31` and `values-night-v31` both, because the qualifier order puts night mode ahead of platform version and a splash written only into `values-v31` is silently ignored on a dark-mode phone. The walk gains `media-card`: after the session block, the card is still posted on the `playback` channel with the playing track's title on it, and `media-keys` below it still gets the transport back — which is what a drawable the shade cannot inflate would actually break. The glyph itself and the splash are screenshots; `dumpsys notification` prints a resource id and never a pixel, and the splash is gone before the walk's first frame. |

android: the falcon on the launcher — a real adaptive icon, with the monochrome layer
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

android: the keep rules, and the release build that proves them
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. |

android: the handoff — the pending rounds, the pipeline, and what is unverified
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. |

android: reorder from the sheet — a playlist row up, down or to the top; a queue row up or down
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. |

android: the phone, on the real core — the mockup shell, playback, the media card, the catalog, the resolver, Save, the dev flavour
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.
