Root cause of "wzp-native not loaded" at runtime on opus-DRED-v2 APK:
libwzp_native.so has a NEEDED entry for libc++_shared.so (because
crates/wzp-native/build.rs uses cpp_link_stdlib(Some("c++_shared"))),
but the APK only contained:
lib/arm64-v8a/libwzp_desktop_lib.so (192 MB)
lib/arm64-v8a/libwzp_native.so (683 KB)
No libc++_shared.so → Android's dynamic linker fails the dlopen of
libwzp_native.so at runtime with "library libc++_shared.so not found",
and every audio path that routes through wzp_native (capture, playout,
register, direct call) refuses to start.
Diagnosis:
- readelf -d libwzp_native.so shows NEEDED libc++_shared.so
- python zipfile listing of the APK confirms libc++_shared.so is
absent from lib/arm64-v8a/
- scripts/build-and-notify.sh (the legacy wzp-android build path)
already had this fix at lines 126-134 with an explicit comment:
"cargo-ndk may not copy libc++_shared.so — grab it from the NDK if
missing". That fix was never ported to build-tauri-android.sh when
the Tauri mobile pipeline was set up.
Fix: after `cargo ndk build -p wzp-native --release` produces
libwzp_native.so into jniLibs, copy libc++_shared.so from the NDK
sysroot (same find pattern as build-and-notify.sh) into the same
jniLibs dir. Abort with a clear error if the NDK doesn't have the file.
Also noting the 191 MB vs 359 MB size discrepancy the user saw: that's
almost entirely libwzp_desktop_lib.so being a 192 MB debug build. The
old working APK was probably a release build (smaller main lib) or
included multiple arches (doubling/tripling the .so count). The size
is cosmetic — the crash is the real issue, and libc++_shared.so is
~2 MB so this fix doesn't close the size gap. Can investigate the
size difference separately after register + direct call work again.

WarzonePhone
Custom lossy VoIP protocol built in Rust. E2E encrypted, FEC-protected, adaptive quality, designed for hostile network conditions.
Quick Start
# Build
cargo build --release
# Run relay
./target/release/wzp-relay --listen 0.0.0.0:4433
# Send a test tone
./target/release/wzp-client --send-tone 5 relay-addr:4433
# Web bridge (browser calls)
./target/release/wzp-web --port 8080 --relay 127.0.0.1:4433 --tls
# Open https://localhost:8080/room-name in two browser tabs
Architecture
See docs/ARCHITECTURE.md for the full system architecture with Mermaid diagrams covering:
- System overview and data flow
- Crate dependency graph (8 crates)
- Wire formats (MediaHeader, MiniHeader, TrunkFrame, SignalMessage)
- Cryptographic handshake (X25519 + Ed25519 + ChaCha20-Poly1305)
- Identity model (BIP39 seed, featherChat compatible)
- Quality profiles (GOOD/DEGRADED/CATASTROPHIC)
- FEC protection (RaptorQ with interleaving)
- Adaptive jitter buffer (NetEq-inspired)
- Telemetry stack (Prometheus + Grafana)
- Deployment topology
Features
- 3 quality tiers: Opus 24k (28.8 kbps) / Opus 6k (9 kbps) / Codec2 1200 (2.4 kbps)
- RaptorQ FEC: Recovers from 20-100% packet loss depending on tier
- E2E encryption: ChaCha20-Poly1305 with X25519 key exchange
- Adaptive jitter buffer: EMA-based playout delay tracking
- Silence suppression: VAD + comfort noise (~50% bandwidth savings)
- ML noise removal: RNNoise (nnnoiseless pure Rust port)
- Mini-frames: 67% header compression for steady-state packets
- Trunking: Multiplex sessions into batched datagrams
- featherChat integration: Shared BIP39 identity, token auth, call signaling
- Prometheus metrics: Relay, web bridge, inter-relay probes
- Grafana dashboard: Pre-built JSON with 18 panels
