a23d9f5e41 feat: foreground service, dB gain sliders, speaker routing, live network stats
- Wire CallService foreground service for background calls (microphone type)
- Add Voice Volume + Mic Gain sliders (-20 to +20 dB) applied in Kotlin
- Connect AudioRouteManager for real speaker toggle via AudioManager
- Feed quinn QUIC RTT into PathMonitor, display Loss/RTT/Jitter from live data
- Nuclear teardown between calls — recreate engine + audio pipeline each call
- Fix re-entrant teardown loop from CallService notification callback
- Park audio threads as daemons to avoid libcrypto TLS destructor crash on exit
- Remove duplicate wakelocks from Activity (service owns them now)
- Strip AEC + denoise from capture path, keep AGC only (incremental approach)
- Fix .so copy target: libwzp_android.so not libwzp.so

b3e56ecbd8 feat: add AGC to capture + playout paths, add server UI, DNS resolve
- Wire AutoGainControl on both capture (mic → encode) and playout
  (decode → speaker) paths to normalize volume levels
- Add server list with add/remove custom server dialog
- Add IPv4/IPv6 preference toggle for DNS resolution
- Resolve DNS hostnames to IP in Kotlin before passing to Rust engine
- Revert to IP addresses for default servers (DNS still broken on QUIC)

AGC confirmed working — voice levels noticeably improved in testing.

2fa07286c3 feat: wakelock for background calls, server selector UI
- Partial wake lock + WiFi high-perf lock during calls — audio
  continues when screen is off / phone is locked
- Server selector: toggle between LAN (172.16.81.175) and Pangolin
  (pangolin.manko.yoga) before connecting
- Room name editable in idle screen

bf91cf25bd feat: add real audio pipeline with Opus + RaptorQ FEC
- AudioPipeline: Kotlin AudioRecord/AudioTrack on JVM threads, PCM
  shuttled to Rust via lock-free ring buffers + JNI
- FEC: RaptorQ fountain codes on encode (5 frames/block, 20% repair
  ratio for GOOD profile), decoder feeds repair symbols for recovery
- Real audio level meter from mic RMS (replaces fake animation)
- Room name editable in UI (default: "android")
- Relay changed to pangolin.manko.yoga:4433
- Stats overlay shows FEC recovered count
- CallState now synced from polled stats (fixes "Connecting" stuck bug)

af85a49e86 fix: eliminate all native thread creation — run everything single-threaded
pthread_create crashes on Android due to static bionic __init_tcb stubs
in the Rust std prebuilt rlibs. This is unfixable without rebuilding std.

Solution: run the entire call (QUIC connect, handshake, media send/recv)
on a single tokio current_thread runtime. The JNI startCall() now blocks,
so Kotlin dispatches it to Dispatchers.IO (JVM thread, not pthread).

Audio pipeline temporarily simplified to silence frames — will restore
once threading is solved (either via Java Thread or rebuilding std).

bae03365da fix: restore getauxval_fix.c + current_thread tokio — both needed
The getauxval override (dlsym wrapper) fixes SIGSEGV in
init_have_lse_atomics at library load time. The current_thread
tokio runtime avoids SEGV_ACCERR in pthread_create/__init_tcb.
Both fixes are required together.

9d9ce4706d fix: use current_thread tokio runtime — avoid pthread_create SEGV on Android
Multi-thread tokio runtime crashes with SEGV_ACCERR in __init_tcb
during pthread_create on Android (static bionic stubs from CRT).
Switch to current_thread runtime which runs network I/O on the
calling thread without spawning additional OS threads.

Also: clean up build.rs — use only libc++_shared.so (dynamic),
remove getauxval_fix.c hack, remove static c++/c++abi linking.

9098e28a1f fix: SIGSEGV in getauxval — override broken CRT stub with dlsym wrapper
compiler-rt's init_have_lse_atomics calls getauxval(AT_HWCAP) at
library load time. The static getauxval from the CRT reads from
__libc_auxv which is NULL in shared libraries → SIGSEGV at 0x0.

Fix: compile getauxval_fix.c that provides a getauxval() which uses
dlsym(RTLD_DEFAULT) to find the real bionic getauxval at runtime.
Also switch to libc++_shared.so (bundled in APK) to avoid pulling
in static libc stubs.

f6d51fce61 fix: target API 26 in ELF — pthread_atfork blocked by bionic at API 21
The .note.android.ident ELF section had API level 0x15 (21), causing
Android's bionic linker to block pthread_atfork (used by rand crate).
Fix: pass -P 26 to cargo-ndk and set linker to android26-clang.
Verified: ELF now shows 0x1a (26).

a8dd0c2f57 fix: also link libc++abi for RTTI — resolve missing __class_type_info vtable
- Compile all 62 Oboe source files (was headers-only, missing symbols)
- Link libc++_static + libc++abi with NDK sysroot search path
- Bump linker target from android21 to android26 (fixes pthread_atfork)
- Link liblog + libOpenSLES for Oboe runtime deps

778f4dd428 fix: link libc++ statically — crash on launch due to missing libc++_shared.so
- Set cpp_link_stdlib(None) to suppress cc crate's automatic linking
- Explicitly link both c++_static and c++abi with NDK sysroot search path
- Fixes RTTI vtable symbol (_ZTVN10__cxxabiv117__class_type_infoE) error
- Verified: only liblog.so remains as dynamic dependency

Closes #001

b204213a01 build: rebuild APK with static libc++ linking (fixes #001)
libc++_shared.so is no longer a runtime dependency — verified
via llvm-readelf. Only system libs (libdl, liblog, libm, libc) remain.

8d5f6fe044 feat: wire QUIC transport, JNI bridge, connect UI + add docs
- Replace raw FFI with proper `jni` crate for string marshalling
- Wire QUIC transport in engine: connect to relay, crypto handshake
  (CallOffer/CallAnswer, X25519+Ed25519), send/recv MediaPackets
- Feed received packets into jitter buffer (was previously ignored)
- Add connect screen UI with CALL button (idle state) and in-call
  controls (mute, speaker, hang up, live stats)
- Hardcode relay 172.16.81.125:4433, room "android"
- Add comprehensive docs in docs/android/:
  architecture.md (8 mermaid diagrams), build-guide.md,
  debugging.md, maintenance.md, roadmap.md

780309fede fix: crash on launch — don't auto-start call, handle null JNI strings, remove stdout tracing
- CallActivity no longer auto-starts a call on launch
- CallViewModel lazily inits engine only when startCall() is called
- nativeGetStats nullable return handled safely in Kotlin
- Removed tracing_subscriber::fmt() which panics on Android (no stdout)
- All JNI calls wrapped in try/catch on Kotlin side
