enricobuehler	3167c936c0	feat(android): mDNS host discovery (NsdManager) in the connect screen ... M4 Android stage 1 (discovery). Kotlin-only — browse _punktfunk._udp and present a tappable host list above the manual Host/Port fields. - clients/android/kit: HostDiscovery — NsdManager browse + resolve (registerServiceInfoCallback on API 34+ for reliable TXT, legacy resolveService on 31-33), MulticastLock while running, and a pure parseTxt(proto/fp/pair/id). Exposes the live host set via an onChange callback (NSD callbacks land on the main thread). DiscoveredHost(name, host, port, fingerprint?, pairingRequired). + a JVM unit test of parseTxt. - clients/android/app: ConnectScreen renders discovered hosts (tap -> fill host/port + connect); discovery scoped to the screen (start on enter, stop on connect/leave). Manifest adds CHANGE_WIFI_MULTICAST_STATE + ACCESS_WIFI_STATE (NEARBY_WIFI_DEVICES already declared). Trust stays TOFU (pin=None); fp shown advisory; pairingRequired shown (SPAKE2 PIN wiring is later). Verified: parseTxt unit test (5/5 green); on the emulator a loopback NsdManager.registerService of a fake _punktfunk._udp host was discovered + resolved + TXT-parsed and rendered as a card (name/host:port/TOFU/fp) -- the full browse->resolve->parse->UI path. Real cross-LAN discovery needs a physical device on the host LAN (the emulator's SLIRP NAT drops mDNS multicast).

enricobuehler	8c8d576e52	feat(android): host→client audio — Opus → AAudio (LowLatency) ... M4 Android stage 1 (audio). An audio thread pulls Opus packets from the connector (next_audio), decodes to interleaved f32 stereo, and feeds AAudio via its realtime data callback through a jitter ring ported from the Linux client (prime ~3 quanta, drop-oldest cap, re-prime on drain). All in Rust on native threads — symmetric with the video decode path. - crates/punktfunk-android: audio.rs (Opus decode + jitter ring + AAudio callback); SessionHandle gains an audio slot; nativeStartAudio/nativeStopAudio JNI; Drop stops it. Android-only deps: opus 0.3 (libopus via cmake, static) + ndk "audio" (AAudio) — pure C/NDK, no libc++_shared to bundle. - clients/android: NativeBridge start/stop audio, called in the SurfaceView lifecycle. - kit/build.gradle.kts: cargo-ndk env for the libopus cmake build (NDK root, Ninja, LIBOPUS_STATIC/NO_PKG) + --platform 31 (libaaudio is API 26+). Verified live (emulator -> gamescope host on the LAN box): AAudio opened 48k/stereo/f32; a 440 Hz tone played into the host capture sink reached the client decoded -- opus ~200/s, pcm_frames climbing in lockstep, peak=0.089 (real content, not silence), with video streaming concurrently. Some underruns under emulator jitter (verify on hardware). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-15 09:25:24 +02:00
enricobuehler	79217eb93d	feat(android): scaffold the native Android client (Rust-heavy JNI bridge) ... Rust-heavy client model (like punktfunk-client-linux): a new cdylib crate crates/punktfunk-android links punktfunk-core and exposes the JNI seam; Kotlin (clients/android) owns only the Android-framework surface. Kotlin can't import the C header the way Swift can, so the bridge is written in Rust to reuse the Linux client's orchestration rather than re-port it. - crates/punktfunk-android: JNI bridge — abiVersion/coreVersion native-link proof + session connect/close handle; plane pumps stubbed for M4 stage 1. - clients/android: Gradle project — :app (Compose) + :kit (Android library with a cargo-ndk Exec task -> jniLibs). AGP 9.2 / Gradle 9.4.1 / Kotlin 2.3.21 / Compose BOM 2026.05.01 / compileSdk 37 / targetSdk 36 / minSdk 31, shipping arm64-v8a + x86_64. Phone + TV (leanback) installable. README rewritten. - .gitea/workflows/android.yml: CI mirroring apple.yml on a Linux runner. - punktfunk-core: switch rcgen to the ring backend so the whole quic tree is aws-lc-free (smaller client .so, cmake-free cross-compile; a win for all targets). Validated on this box: :app:assembleDebug -> APK with both ABIs; emulator first-light renders the bridge linked (core ABI v2) with logcat confirmation; clippy -D warnings + cargo fmt clean; core tests green on the ring backend.
