NeriPlayer — a multi-source, local-first, native Android audio player

01Now Playing · 正在播放

Every song has its own colors.

The phone below is redrawn from the app's source and checked against real screenshots item by item — layout, sizes, colors and how every button responds. The demo track “星轨” (Startrail) comes from NeriPlayer PV; press play and it really sings.

Colors pulled from the cover, blended into a flowing background: 5colors
The fluid background needs Android 13 or later; older versions get a plain one: Android13+

Media3 / RuntimeShader

01Cover colors, turned into a fluid background

The Now Playing background is drawn by BgEffectPainter, which loads a GLSL / AGSL shader and renders it frame by frame through RuntimeShader. Palette first pulls five color roles from the cover — Base, Accent, Light, Dark and Bridge — then blends them into flowing patches and grain, wired to uMusicLevel / uBeat so it moves with the beat. It is not just a Gaussian-blurred cover.

Base Accent Light Dark Bridge

This background is the app's own shader, ported to WebGL ↗

WaveformSlider

02Progress and controls, right where your thumb is

While playing, the progress bar becomes a slowly flowing wave; on pause it settles into a straight line, and while buffering it turns into a beating pulse. Underneath, quality, codec and format show as configured — like RAW · 48 kHz for this FLAC — and dragging gives haptic ticks along the lyric timeline.

Now Playing controls position

Holding the phone in one hand? Move shuffle, previous, play, next and repeat down within thumb reach, and bring the progress bar along if you like. While the controls sit at the bottom, the Dock becomes a regular toolbar so the two never overlap.

01About 30 dp wavelength and 2.3 dp amplitude, one cycle every two seconds
02Tap the quality tag to switch; speeds other than 1.00× get their own label
03Controls on Now Playing and the lyrics page each come in small, medium and large

SyncedLyricsView

03Word-by-word lyrics on the cover page, too

Under the controls sits a strip of synced lyrics: the current line lights up word by word, its translation follows only that line, and the rest fade quietly to the side. Tap a line to jump there, long-press to share. If it feels crowded, the cover-page lyrics and the bottom toolbar can each be turned off.

0118 sp on the cover page, 14 sp for translations, sized separately from the lyrics page
02Swipe left for the full lyrics page

PlaybackEffectsController

04Audio effects & speed

Tap “More” in the top-right corner, then “Audio Effects & Speed”: speed and pitch are set independently, loudness enhancement steps in dB, and the equalizer binds to the current playback session with 23 built-in system presets — or drag the manual bands from 60 Hz to 14 kHz one by one. Playback settings add per-track real-time loudness normalization, channel balance, 32-bit hi-res output, fades and crossfades.

Press play first, then try a preset or a speed — you'll actually hear it change ↗

02Lyrics · 歌词

Original and translation, lit as one.

The full lyrics page hands the whole screen to the words: the current line turns bold and bright, the translation sits right beneath it, and distant lines slowly blur away with depth of field. The “Trans” chip in the lower left tucks translations away or brings them back.

Fig. 02 — Lyrics page, the word-level timeline of “星轨”

LRC / YRC / TTML

02Deep lyrics, in the spirit of Apple Music

Line-synced and word-synced LRC (including line-end times and bracketed word timestamps), YRC and TTML are all supported. The lyrics page only shows options the current song can actually use, and after a track change it waits until lyrics are resolved before fading in — no flash of empty space.

01Tap a line to jump to it; long-press to select lyrics, copy text, share the song or render a 1080px lyric card
02Lyric offsets can default per source; font sizes are set separately for the cover page and the lyrics page
03Source preference: Auto / NetEase / Kugou / QQ Music / LRCLIB / AMLL TTML, with word-synced lyrics preferred when matching by hand
04Floating lyrics, status-bar lyrics, SuperLyric, Lyricon and Bluetooth lyrics all reuse the same playback data

Fig. 02b — with romanization (illustration)

星の線路をそっと辿って

hoshi no senro wo sotto tadotte

For Japanese songs that ship with romanization, the secondary line can switch to it: it also sits right beneath the original, taking the translation's place instead of floating above. When a song has no romanization, the option simply isn't there — like “星轨” above, which only has “Trans”.

03Sources · 多源

One player, four lines.

Each platform is searched on its own and never mixed in — yet playback, downloads, playlists, history and stats share one set of local data and one playback core. Source resolution, failure recovery and automatic fallback are all orchestrated by PlayerManager.

07Sync & Privacy · 同步与隐私

Your data, in your hands only.

NeriPlayer has no central server. Metadata such as playlists, favorites, recent plays and play stats only syncs to your own GitHub repository (private by default when created in the app) or WebDAV.

04Atomic publishingGitHub updates conditionally via GraphQL beforeOid; WebDAV uploads immutable objects first, then writes the manifest with a strong ETag

Four promises

01
No ads, no tracking.
No ad SDKs, third-party analytics or crash-reporting SDKs.
02
No public music library.
No cloud media distribution, and no personal data gathered into the maintainers' hands.
03
Credentials stay on the device.
Audio cache, downloads, cookies and playback tokens are never uploaded.
04
Your accounts, protected.
Local play history is never written back to third-party platforms, so it won't trip risk controls or suspicious-login checks.

07bPlay stats

Play counts, listening time and daily buckets are recorded against each song's stable identity, and they take part in sync merges too.

plays: 186
hours listened: 11.2
songs: 74

Listening time

Week / month / year use rolling 7 / 30 / 365-day windows; the weekly hot list only counts songs with at least 10 minutes of total listening, and the monthly list needs 30. Neither the GitHub repository nor the WebDAV files are end-to-end encrypted, so keep them safe.

Phones stay locked to portrait, and only Now Playing can rotate; tablets held upright get a Now Playing layout of their own.

10Details · 细节

The little details you meet every day.

Easy to overlook, but you run into them every day — so they got the same care.

10.1

Home screen widgets

4×2 · 2×2 · 4×1

Material You rounded cards colored from the cover, adapting to light and dark themes, large fonts and both orientations. The wide card adds favorite and desktop-lyrics buttons; even the narrow sizes keep previous, play and next, and elapsed time ticks every second while playing.

Shown: the widget previews bundled with the app.

10.2

Launcher shortcuts

Long-press the app icon to jump straight in; when there's no queue to restore, you get feedback instead of a silent failure.

10.3

Mini player, swipe to skip

Swipe the bottom mini player left or right for the previous / next track; tap to expand and play / pause work as usual.

10.4

Floating & status-bar lyrics

Floating lyrics let you set color, outline, size, position and alignment; Meizu status-bar lyrics, SuperLyric, Lyricon and Bluetooth lyrics are supported.

10.5

In the car

Android Auto and devices with AVRCP browsing can browse the queue and playlists and search the library; connecting never starts playback by itself.

10.6

Safe mode

$ launch moe.ouom.neriplayer
! ANR on last launch
→ entering safe mode
  Preview · Copy · Export logs

JVM crashes, native crashes and system ANRs are all recorded; after an abnormal exit, full initialization is skipped and the app goes straight into safe mode.

10.7

Resume long audio

Long podcasts and multi-part videos pick up where you left off; an explicitly requested position always wins over the remembered one.

10.8

Developer mode

It works the same on a real device: tap the version 7 times in Settings and a Debug tab appears in the nav bar, with per-platform probes and a log viewer.

11Inside · 构造

Fourteen modules, each minding its stretch.

The in-house Android libraries are split by domain, with dependency direction enforced in CI: :model depends on no implementation, :common on no business logic, and no library may depend on the app or form a cycle. The colored dots match the feature sections they serve.

iFAQ · 常见问题

Anything you'd like to ask?

Q.Does NeriPlayer cost anything? Can I donate?

It's completely free and open source under GPL-3.0. Because of the nature of the project, the maintainers don't accept sponsorships, donations or commercial funding of any kind. If you'd like to support it, open an issue or a PR, or share it with someone who needs it.

Q.Does it come with music?

No. NeriPlayer doesn't run a public cloud library or any media distribution service. Online features rely on your own authorized accounts on third-party platforms, and premium or restricted content still follows each platform's rules. Only access, play or save content you own the rights to, are authorized for, or that the platform's rules allow.

Q.Where does my data get uploaded?

Nowhere, by default: playback cache, downloads, playlists, history, stats, settings and credentials all stay on your device. Only when you turn on GitHub or WebDAV sync does metadata — playlists, favorites, recent plays and play stats — get written to a remote you control. Audio cache, downloads, cookies and playback tokens are never uploaded to anyone.

Q.Why not sync play history back to NetEase and other platforms?

It's not that the app can't. But clients of centralized music platforms usually come with risk controls and behavior sampling, and reporting local play history directly could trigger suspicious-login flags, abnormal-playback flags or even a frozen account. To keep your account safe, NeriPlayer doesn't upload local play history or stats to these platforms for now.

Q.Which Android versions are supported?

Android 9 (API 28) and later. The RuntimeShader fluid background and advanced blur on Now Playing need Android 13+, and cover blur needs Android 12+; older versions fall back gracefully without affecting playback itself.

Q.Where is lyric romanization?

It only appears when the current song has romanization data. When it's on, romanization sits right beneath the original, in the translation's place; songs without it (Chinese songs, for example) only show “Trans”.

Q.Do I have to host my own server for Listen Together?

Not necessarily. You can use a server someone else has deployed, or deploy your own NeriPlayer-LTW to Cloudflare Workers in one click, then enter its address in Settings and test it. Room codes are 6 readable characters; local songs can't start a Listen Together room.

Q.Is GitHub / WebDAV sync end-to-end encrypted?

No. Credentials are stored on the device encrypted with Android Keystore, but files synced to the remote aren't end-to-end encrypted, so keep your repository and WebDAV account safe. A full config export includes credentials — it's meant for moving your own setup, so don't share it publicly.

Q.Will USB exclusive work with my DAC?

It currently targets UAC1.0 devices and UAC2.0-compatible Type I PCM devices. UAC2 asynchronous links only accept devices with a single resolvable explicit feedback endpoint and a supported clock topology; anything else takes the compatible fallback. If the system restricts playback with the screen off, lift the battery and background restrictions as Settings suggests.

Q.Found a problem — what's the best way to report it?

First tap the version 7 times in Settings to turn on developer mode; the app then writes file logs, with crash logs saved separately. Then open a GitHub issue with your Android version, device model, app version, steps to reproduce and the relevant logs. You can also filter logs with adb:

adb logcat | findstr NeriPlayer   # Windows
adb logcat | grep NeriPlayer      # Linux / macOS

Also note that a global proxy can make some third-party APIs return bad data, so set up your proxy rules sensibly.

Many sources, local first, native Android.
