A port of hyoromo's 2010-era Hatsune Miku launcher themes into a modern Android
icon pack that works on essentially any third-party launcher. No ads, no
telemetry, no permissions — just 28 icons and an appfilter.xml.

This project contains none of my original artwork. Everything visual here belongs to the people below, and the port exists only because they made it first.
Every icon in this pack was drawn by Niboshi, a Japanese illustrator and PV artist who was prolific in the VOCALOID scene around 2008–2011, creating art and videos for producers including Lovely-P, Kuchibashi-P and u160. Their work is credited on Niconico under both にぼし and あたたたP.

The chibi Miku sprites, the leek-handled house, the folder art and the app drawer furniture are all theirs. Please do not reuse these images outside the spirit of the original themes.
hyoromo built and published the original launcher themes that these assets were shipped in, and continues to publish Android apps today.

The two themes this pack is derived from are both still on the Play Store:
| Theme | Package | Downloads | Rating |
|---|---|---|---|
| GO Launcher EX Theme -Miku- | jp.hyoromo.golauncherex.miku |
500K+ | 3.8★ (337) |
| ADW Theme -Miku Hatsune- | jp.hyoromo.adwtheme.miku |
100K+ | 4.1★ (142) |
Both were last updated in March 2015. If you are running GO Launcher or ADW, install the originals instead — they are the real thing and they still work.
The original themes only work in GO Launcher and ADW Launcher, and the reason is worth explaining because it is not obvious.
Those themes are a bag of PNGs named by function: phone.png, browser.png,
gmail.png, folder_open.png. They work because the launcher itself contained a
hardcoded lookup table — GO Launcher's code effectively said "when drawing the
dialer, load phone.png out of the theme package". A launcher that did not
implement GO's private naming convention had no idea what to do with the files,
and there was no way to theme an app that was not already on the launcher's list.
Around 2011 ADW introduced appfilter.xml, which inverts the relationship. Rather
than the launcher knowing about the pack, the pack declares the mapping:
<item component="ComponentInfo{com.google.android.dialer/com.google.android.dialer.extensions.GoogleDialtactsActivity}"
drawable="phone" />Nova, Apex, Action, Lawnchair, Niagara, Smart Launcher, Microsoft Launcher and others all adopted that same format. It has never been an official part of Android — it is a convention everyone copied. Universal compatibility comes down to four things, all of which this pack implements:
res/xml/appfilter.xml— the component-to-drawable mapping.- Manifest intent filters — one per launcher dialect, so each launcher's icon pack picker can find the package at all.
res/xml/drawable.xml— a flat list of every drawable, which populates the launcher's manual icon picker.- An activity that returns
Intent.ShortcutIconResource— so "long-press an app → Edit → tap the icon" can pull an icon out of the pack by hand.
| App name | Hatsune Miku Icon Pack |
| Package name / application ID | com.hatsyrei.mikuiconpack |
| Repository | https://github.com/HatsyRei/hatsune-miku-icon-pack |
| Min SDK | 23 (Android 6.0) |
| Permissions | none |
The package name is what a launcher's icon pack picker identifies the pack by,
and what adb install/adb uninstall take as an argument:
adb install app-release.apk
adb shell pm uninstall com.hatsyrei.mikuiconpack28 icons, all of them from the original themes:
- 20 app icons — browser, calculator, calendar, camera, clock, contacts, email, facebook, gallery, gmail, gtalk, maps, market, messaging, music, phone, settings, twitter, voicesearch, youtube.
- 8 pieces of launcher furniture — the app drawer button, app panel frames, folder art, drag targets and the leek house. Nothing consumes these automatically any more, but they are exposed in the picker so you can assign them by hand.
appfilter.xml deliberately stays close to what hyoromo's themes covered: each
icon is mapped to the app it was drawn for, plus that app's modern successors
(Android Market → Play Store, Google Talk → Hangouts → Google Chat, and so on).
It does not try to guess at hundreds of unrelated apps. Anything unmapped keeps
its stock icon, and you can always assign an icon by hand from the picker.
The five wallpapers that shipped with the ADW theme are kept in art/ for
reference but are not bundled into the APK.
The manifest advertises twelve theme actions: ADW and ADWEx, Nova, Apex, GO Launcher EX, LauncherPro, Atom, Lawnchair, Smart Launcher, Action Launcher, Sony Xperia Home and Phonemetra Turbo. Launchers that read Nova's or ADW's action — which is most of them, including Niagara and Kvaesitso — are covered too.
Requires JDK 21, an Android SDK with API 37 and ImageMagick.
./build.sh # regenerate assets, then assemble a release APK
./build.sh debug # debug APK
./build.sh install # release APK, then adb installOutput lands in app/build/outputs/apk/release/app-release.apk. Release builds
are signed with the auto-generated debug key.
Nothing under app/src/main/res is authored by hand. build.sh regenerates it
all from art/miku-hyoromo/ before every build:
| Script | Output |
|---|---|
tools/upscale.sh |
drawable-nodpi/*.png — 144×144, Lanczos |
tools/gen_launcher_icon.sh |
mipmap-*/ic_launcher.png and the adaptive foreground |
tools/gen_drawable_xml.py |
res/xml/drawable.xml |
Only appfilter.xml is maintained by hand, since it encodes decisions rather
than file listings.
The originals are 72×72, and they are resampled to 144×144 — an exact 2×. An
integer factor resamples more cleanly than an awkward one, and 144 happens to be
what an xxhdpi (1080p) launcher asks for, so on the most common class of phone
nothing is scaled at run time at all. Doing the work offline with Lanczos also
beats letting the launcher stretch a 72px bitmap with bilinear filtering at draw
time. drawable-nodpi stops Android from scaling them a second time.
isShrinkResources is deliberately off. Nothing inside the APK references
these drawables — launchers resolve them by name, by reflection, from another
process — so the resource shrinker cheerfully deletes every single one. This is
a common way for icon packs to ship completely broken.
The MIT license in LICENSE covers the code in this repository: the Gradle
setup, the generator scripts, the XML plumbing and the Compose UI.
It does not cover the artwork. Those images are Niboshi's work, published as part of hyoromo's themes, and depict Hatsune Miku — a character owned by Crypton Future Media and governed by the Piapro Character License. Treat them accordingly: this is a fan port, not a redistribution license.
