Device scanning & pairing · bidirectional RFCOMM serial with directional commands · auto data logging · draggable floating receive window.
UDP/TCP multicast, KCP reliable UDP, Pub/Sub floating dialogs, 64 KB/chunk file transfer with progress, embedded HTTP server (FS & SAF) with sortable listing + in-page viewer, SSH server (Apache MINA SSHD) on port 2222 as a foreground service.
MarketActivity + market/ + KLineView; keyless public HTTPS; bar fields (time, open, high, low, close, volume, amount) match the matkline.py toolset.
Sources (QuoteSource): auto (smart pick + fallback), tencent (A-shares/indices/funds), eastmoney (A-shares/futures/HK), gold/xau/gc, crude/brent/ng, usd (USD index), binance (crypto). Intervals span 1m…1M per source.
Features: code / name / pinyin input with picker · candles + MA5/10/20 + last-price line · indicators (MA / Volume / MACD / RSI / KDJ) · drag-pan, pinch-zoom, crosshair tooltip · 15s auto-refresh · persisted prefs · home widgets — 📈 Quotes (2×2 resizable, per-instance source+symbol) and the 行情曲线 chart widget (single-symbol trend sparkline, resizable, 2×2-friendly; 黄金标的额外标注人民币价 元/克).
Thread-safe queue (Message.h) + MASSAGER enum bridging native and UI: toast/status/hint, pub-sub feedback, file progress, texture, UDP server/client, KCP status. SelectActivity shows dual status (txt_hint / txt_status) with day/night-aware colors.
GPU (EGL/GLES2) & CPU image/video rendering · 16 kHz PCM recording with live waveform · WAV/MP4/OGG/MP3/AAC/AMR playback + waveform · built-in STT.
On-device parametric model (no cloud). A photo contributes appearance + silhouette proportions; the user supplies the absolute scale. Engine picker on entry:
| Engine | Description |
|---|---|
Native (原生) |
SDF implicit surface + SurfaceNets — fully procedural body & face |
High-res (高分) |
Anny (naver/anny, Apache-2.0, MakeHuman/CC0): phenotype params drive prototype blendshapes; baked offline by tools/export_anny_targets.py → anny.mhb, solved on device as w = Π c; falls back to Native if missing |
Regenerate
anny.mhb:python3 tools/export_anny_targets.py export --anny-dir /path/to/anny --out app/src/main/assets/anny/anny.mhb(or--syntheticfor a placeholder;selftestchecks byte-exactness). Bakes gender/muscle/weight/height into 56 multi-linear blendshapes.
Features: photo / cloud (Tripo3D) input · silhouette & color extraction · body params (gender/height/weight/head ratio + girth tuning) · face shapes & 8 hairstyles · life-size mesh + measurements (BMI, circumferences, inseam) · OpenGL ES preview (grid/ruler/shadow) · OBJ+MTL export & PNG screenshot · persisted prefs.
Multi-provider AI chat (Chat / Reasoner) · acceleration alert at 7.0 m/s².
ChatBox providers: DeepSeek (falls back to the built-in key) · Ollama — self-hosted (host/IP editable, port defaults to 11434) or Ollama Cloud · OpenRouter. Ollama and OpenRouter fetch the model list from the service on demand — OpenRouter is filtered down to free models — and the chosen model is remembered per provider. Text attachments are read and sent with the message.
Observer event bus · native time sync · global 3s toast · one-tap exit.
