Build #7 crashed at launch on the Pixel 6 with SIGSEGV in __init_tcb / pthread_create called from tao::ndk_glue::create in WryActivity.onCreate: #00 __init_tcb(bionic_tcb*, pthread_internal_t*)+4 #01 pthread_create+360 #02 std::sys::thread::unix::Thread::new #04 tao::platform_impl::platform::ndk_glue::create #05 Java_com_wzp_desktop_WryActivity_create Tauri scaffolds build.gradle.kts with `minSdk = 24`, which makes the tauri-cli invoke `aarch64-linux-android24-clang` as the Rust linker. That linker transitively pulls broken static stubs from libc.a for getauxval, __init_tcb and pthread_create — these stubs only work in statically- linked executables because they read bionic state (__libc_auxv, TCB) that only the libc init path sets up. In a .so loaded via dlopen they SIGSEGV the moment anything spawns a thread. API 26+ has the real runtime symbols and the NDK-26 linker resolves them against libc.so instead of the static fallback. This is also the minimum Oboe supports. Patch the generated build.gradle.kts post-init to swap `minSdk = 24` for `minSdk = 26` — the legacy wzp-android crate solved the same issue with a .cargo/config.toml linker override plus a getauxval_fix.c shim.

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
