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.
