name = "punktfunk_android"

[dependencies]
# The whole protocol/transport/FEC/crypto + the embeddable NativeClient connector. `quic` pulls
# the punktfunk/1 control plane, whose TLS runs on aws-lc-rs (see punktfunk-core/Cargo.toml) —
# aws-lc-sys cross-compiles for all three ABIs with the NDK clang cargo-ndk already exports.
punktfunk-core = { path = "../../../crates/punktfunk-core", features = ["quic"] }
# 0.22, NOT 0.21 — and the version is load-bearing beyond currency: `rustls-platform-verifier`
# (via quinn-proto, for Android cert verification) already depends on jni 0.22, so pinning 0.21
# here compiled TWO jni copies into the one .so. Matching it collapses them and, with them, the
# whole windows-rs 0.42 generation jni 0.21 dragged in behind `cfg(windows)` (windows-sys 0.45 —
# the oldest crate in the tree — plus windows-targets 0.42.2 and its seven per-arch import libs)
# and jni 0.21's `cesu8`: 11 crates, for a dependency that never even builds on Android.
#
# NOTE for whoever next tries to retire thiserror 1.0 or the jni-sys 0.3/0.4 split: jni is no
# longer why they are here. Both now come solely from `vendor/ndk` 0.9.0 (thiserror 1.0.23,
# jni-sys 0.3) and the crates.io `ndk-sys` 0.6 (jni-sys 0.3). jni-sys 0.3.1 is itself a facade
# over 0.4.1, so the "split" cannot close until ndk + ndk-sys move — and ndk is vendored for one
# visibility patch, so bumping its deps would mean rewriting the vendor rather than a version edit.
jni = "0.22"
log = "0.4"
# LAN host discovery: browse the host's `_punktfunk._udp` mDNS advert — the SAME crate + service the
# Linux/Windows clients use (`crates/pf-client-core/src/discovery.rs`), replacing Android's per-OEM
# `NsdManager` system daemon with one tested browse path. Pure Rust (socket2/if-addrs/mio), so it
# cross-compiles to the Android targets AND builds on the host (the JNI seam links into
# `cargo build --workspace`). Kotlin keeps only the Wi-Fi `MulticastLock` + permission UX.
mdns-sd = "0.21"
# Android-only deps. Gated so `cargo build --workspace` on the Linux/macOS dev boxes + CI still
# compiles this crate (as a host cdylib) — the Android-framework glue (logging, AMediaCodec + AAudio
# via `ndk`, the Opus codec) is only pulled in for the real `*-linux-android` targets.
[target.'cfg(target_os = "android")'.dependencies]
# Default features only, DELIBERATELY: 0.15 added an opt-in `android-api-30` feature that routes
# level filtering through `__android_log_is_loggable_len` so logcat's system-wide/process-wide
# level overrides (`setprop log.tag.*`) are honoured. That symbol is API 30 and the feature
# HARD-LINKS it — on our minSdk-28 floor (Android 9/10) `System.loadLibrary` would fail outright,
# the same way ndk 0.9.0 hard-linking `AMediaCodec_setOnFrameRenderedCallback` broke every
# pre-Android-13 device (see the `ndk-sys` note below). Do not enable it while minSdk is 28.
android_logger = "0.15"
# Feature bridge, no code here: punktfunk-core logs through `tracing`, but this client only
# installs `android_logger` (a `log` backend). Core transport warnings (e.g. "UDP socket buffer
# capped well below target") reach logcat only via tracing's "log" feature, which forwards events
# as `log` records when no tracing subscriber is set (always, here). Today that feature happens to
# be enabled transitively — quinn's default `log` feature unifies `tracing/log` onto the whole
# graph — but nothing about this client's logging should hinge on a QUIC crate's default feature
# set, so declare it explicitly.
tracing = { version = "0.1", default-features = false, features = ["std", "log"] }
# NDK bindings. "media" = AMediaCodec/ANativeWindow (video); "audio" = AAudio (audio playback).
# Pure-Rust FFI to libmediandk/libnativewindow/libaaudio — no C++/libc++_shared to bundle. Decode +
# audio run entirely in Rust on native threads (the "no async on the hot path" invariant).
# api-level-28 matches the app's minSdk floor (Android 9). AAudio (26), AMediaCodec (21) and
# ANativeWindow_setBuffersDataSpace (28) are all ≤28; every call above the floor —
# ANativeWindow_setFrameRate (30), …WithChangeStrategy (31), AMediaCodec_setOnFrameRenderedCallback
# (33), the ADPF hints — is dlsym-resolved at runtime (decode::try_set_frame_rate,
# decode::install_render_callback, adpf), never linked, so the .so still loads on API 28+.
ndk = { version = "0.9", features = ["media", "audio", "nativewindow", "api-level-28"] }
# Raw FFI *types* for the one AMediaCodec entry point the `ndk` wrapper lacks:
# `AMediaCodec_setOnFrameRenderedCallback` — the per-frame render-timestamp callback behind the
# HUD's `display` stage (see decode::DisplayTracker). The symbol is API 33 ("Available since
# Android T"), ABOVE the minSdk-28 floor, so it is dlsym-resolved at runtime
# (decode::install_render_callback), NEVER hard-linked: 0.9.0 hard-linked it and
# `System.loadLibrary` failed on every pre-Android-13 device. Only ndk-sys's pointer/typedef
# types are referenced, which creates no import. Reaching it needs the codec's raw pointer, which
# is why the workspace pins `ndk` to the vendored copy whose only patch makes `MediaCodec::as_ptr`
# public (vendor/ndk, wired in the root Cargo.toml).

# Opus decode for the host→client audio plane (0xC9: 48 kHz stereo, 5 ms frames). Same crate the
# host + Linux client use. audiopus_sys vendors libopus (pure C) and builds it static via cmake —
# the cargo-ndk build sets LIBOPUS_STATIC=1/LIBOPUS_NO_PKG=1 so it links the bundled lib, not the host's.
opus = "0.3"
# Tier-A pad audio (WP9). Android's audio framework denylists the DualSense's output by VID/PID,
# so the pad's isochronous endpoint is driven directly on the fd `UsbDeviceConnection` hands over.
# Our own crates, developed openly because the hole they fill — isochronous USB in Rust — is an
# ecosystem-wide one: https://github.com/unom-io/usbfs-iso
# Pinned by revision rather than floating: this is a transport under a real-time deadline and it
# should move when we choose to. Becomes a plain version dependency once the crates are published.
