The Android half of andTunes had been paused on a 1 GB toolchain download (Gradle wrapper, Android Gradle Plugin, Kotlin). None of that was needed: platform 33 and build-tools 34 were already in ~/Android/Sdk, and an app that links no libraries needs five SDK steps, not a build system. andtunes/build.py runs aapt2 -> javac -> R8 -> zipalign -> apksigner and produces a 61 KiB APK. andTunes 0.1.0 is framework-only Java: a six-tile menu that loads nothing, a streaming library.json parse grouped into artists and albums in one pass, one ListActivity for every list (songs and artist songs open with Shuffle all, albums carry art thumbs, search as you type), a Now playing bar under every list, and a white Now Playing screen with square art, a slim scrubber, prev/play/next, shuffle and repeat, and no back button. A foreground PlaybackService owns the queue: audio focus, becoming-noisy, MediaSession and a MediaStyle notification, end of queue pauses, missing files skip, and the last queue and position come back on launch. Black on white, and every size doubled for the R1's override density. Cold start to the menu: 313-338 ms. The scroll wheel turned out to be DPAD_UP/DOWN (stock Generic.kl), not volume. The app takes both in dispatchKeyEvent: lists scroll a row per detent, and the menu and Now Playing get volume. LinTunes side: Connections > Install andTunes on Rabbit... installs the committed APK over adb and grants all-files access, or copies it to Download/ over MTP when there's no adb. Sync fills Buttons/ with default artwork only where a file is missing, so trav's own art is never overwritten. Verified against the dev library only, synced to the R1 and driven with adb input + screencap.

# andTunes — task board
|
||
|
||
A music player for the Rabbit R1 that never scans anything: LinTunes writes
|
||
`Music/andTunes/library.json` during sync and the app just reads it. See
|
||
`../andTunes spec.txt` for the original brief.
|
||
|
||
Legend: `[ ]` todo · `[~]` in progress · `[x]` done.
|
||
|
||
**Status: 0.1.0 plays music (2026-09-11, LinTunes round 50).** Built with
|
||
`python3 andtunes/build.py` — plain Java, no Gradle, nothing downloaded (see
|
||
`README.md`, *Toolchain*). Phases are andTunes' own; which LinTunes round
|
||
each lands in is decided when it starts.
|
||
|
||
## Device facts (measured 2026-09-06, `adb shell wm size` etc.)
|
||
|
||
- Panel **480 × 640 px**, physical density 320, **override density 160** — so
|
||
the app sees a 480 × 640 **dp** canvas on a 2.88" screen (~278 real ppi).
|
||
- **One dp is about half its usual physical size here.** Double every stock
|
||
value: body text 28–32 sp, list rows ≥ 88 dp, menu tiles ~213 dp. A 48 dp
|
||
row would be 4.4 mm tall. Do not "fix" this by changing the device density —
|
||
trav likes it where it is.
|
||
- Android 13 / API 33, `gsi_r1-userdebug`, arm64-v8a, 65 GB free.
|
||
- Scroll wheel = input device `och1970_holl_key` → **KEY_UP / KEY_DOWN**,
|
||
mapped by the stock `Generic.kl` (checked 2026-09-11 via `dumpsys input`)
|
||
to **`KEYCODE_DPAD_UP` / `DPAD_DOWN`** — not volume. Side/PTT button sits
|
||
on `mtk-kpd` with KEY_VOLUMEDOWN + KEY_POWER. Headset exposes
|
||
KEY_PLAYPAUSE, so a MediaSession gets media keys for free.
|
||
- USB: set to come up as **`mtp,adb`** whenever the screen is unlocked
|
||
(`adb shell svc usb setScreenUnlockedFunctions mtp`, 2026-09-11), so the
|
||
gvfs mount sync uses and the adb install uses are both there at once.
|
||
|
||
## Phase 1 — plays a song (v0.1.0) ✔
|
||
|
||
- [x] `java-21-openjdk-devel` — installed, `javac` on PATH. (Java 25 is also
|
||
present; `build.py` points at 21.)
|
||
- [x] Android SDK: platform 33 + build-tools 34.0.0 were already in
|
||
`~/Android/Sdk`. **No Gradle, no Kotlin** — `build.py` runs aapt2 →
|
||
javac → R8 → zipalign → apksigner directly (trav, 2026-09-11: don't
|
||
pull a GB over cell if it isn't needed; it isn't).
|
||
- [x] Project, package `me.teafry.andtunes`, minSdk 26 / targetSdk 33,
|
||
framework only: `Activity`, `ListView`, `MediaPlayer`, `MediaSession`,
|
||
`Notification.MediaStyle`, R8. The APK is 61 KiB.
|
||
- [x] `MANAGE_EXTERNAL_STORAGE` + a first-run screen that sends the user to
|
||
the toggle (LinTunes' installer grants it over adb, so it rarely shows).
|
||
- [x] Library loader: `android.util.JsonReader` streaming parse off the main
|
||
thread into a process singleton; artists/albums grouped in one pass;
|
||
an unknown `format` gets a readable message; reloads when
|
||
`library.json` changes (a re-sync) the next time the menu resumes.
|
||
- [x] `MenuActivity`: six tiles, 2 × 3, **loads nothing**. The sixth reads
|
||
"Now Playing" or "Shuffle All" depending on the service.
|
||
- [x] `ListActivity` in songs mode + "Shuffle all" header row.
|
||
- [x] `PlaybackService` (foreground) + `NowPlayingActivity`: white
|
||
background, square art, slim scrubber, ◀ ⏯ ▶, shuffle, repeat.
|
||
**No back button.**
|
||
- [x] Audio focus, ACTION_AUDIO_BECOMING_NOISY, MediaSession + notification.
|
||
- [x] End of queue **pauses** unless repeat is on. Repeat: off / all / one.
|
||
- [x] `adb shell am start -W`: **313–338 ms** cold to the menu (551 ms on the
|
||
very first launch after install, which includes dex verification).
|
||
|
||
## Phase 2 — the rest of the screens ✔
|
||
|
||
- [x] Playlists, artists (→ "All songs" + albums; all songs has its own
|
||
shuffle), albums, search (artists, albums and songs as you type).
|
||
- [x] Album art thumbs in album rows, full art on now playing.
|
||
- [x] The "Now playing" bar at the bottom of every list screen; the playing
|
||
song is drawn inverted in any list it appears in.
|
||
- [x] Scroll wheel → list scrolling (one row per detent), volume on the menu
|
||
and now-playing screens. Taken in `dispatchKeyEvent`, DPAD *and*
|
||
VOLUME codes, down *and* up, so the search box can't swallow it.
|
||
- [x] Replaceable button images: `Buttons/<name>.png` beats the bundled
|
||
drawable, for the six menu tiles plus ◀ ▶ ⏯. LinTunes ships the
|
||
defaults into `Buttons/` only where the file is missing.
|
||
- [x] Missing file (synced then deleted) skips with a toast, doesn't stop
|
||
the queue.
|
||
- [x] Resume last queue + track + position on launch (paused).
|
||
|
||
## Phase 3 — install from LinTunes, counts coming back
|
||
|
||
- [x] `Connections → Install andTunes on Rabbit…` (LinTunes 0.19.0):
|
||
`adb install -r` + the two permission grants; says Install / Update /
|
||
Reinstall from the version on the device; with no adb, copies the APK
|
||
to `Download/` over MTP for a manual tap. APK committed at
|
||
`lintunes/android/andTunes.apk` (+ `andTunes.json`, its version).
|
||
- [ ] Format gate shaped like `export/web_support.py`: deny-by-default on
|
||
suffix, protected AAC refused, anything else unplayable converted to
|
||
**FLAC** (never a lossy re-encode).
|
||
- [ ] Play counts back: the app writes `plays/andtunes-<installid>.json` in
|
||
the per-machine-totals shape of `storage/play_journal.py`; sync copies
|
||
it back and folds it in. The R1 becomes one more machine in the Round 38
|
||
model — no new merge rules.
|
||
- [ ] Retire `Sync Playlist to Rabbit (Auxio)` now that andTunes covers it.
|
||
(trav's R1 has no old `Music/<Playlist>/` folders, so no cleanup.)
|
||
|
||
## Parked
|
||
|
||
- Gapless, crossfade, EQ, ratings, folder browsing, sleep timer, Android Auto.
|
||
- Deleting the old per-playlist folders automatically. They're outside the
|
||
andTunes root and the containment guard makes them unreachable on purpose;
|
||
removing them should be an explicit, separately-confirmed action.
