Kotlin 层三个文件（刻意零第三方依赖，纯 View 布局——阶段 1 只验证链路）： - RustBridge.kt：android-ffi 的 JNI 声明 + 帧头拆解（25 字节定长头 + Annex-B 载荷） - H264Decoder.kt：MediaCodec 同步模式 + Surface 直出；内置两条实测教训—— 只用 getInputBuffer(i)（Exynos Quirk）、awaitingIdr 状态机（R-3 跳帧断参考链） - MainActivity.kt：连接/解码循环/触摸绝对坐标映射；断开顺序遵守 「先停解码线程 join 后 destroy」的 FFI 纪律 构建链（build-android.ps1，一条命令：cargo ndk -> .so -> gradle assembleDebug -> 安装启动）： - 路径自适应（ 定位仓库根），local.properties 自动生成 - gradle.properties 固定 JDK 17，不动全局 JAVA_HOME 真机验收（vivo S6 / 192.168.1.163 -> PC / 192.168.1.180:47800）： - agent 日志：peer connected + auth ok, desktop 2560x1440 - 手机截图：Windows 桌面（WPS 文件列表）已渲染在 SurfaceView 上 证据：evidence/screen-connected.png（本地，不入库） 已知环境限制（记录在个人层 baseline）：本机 Windows 防火墙的 agent.exe 程序级放行规则对 UDP 入站不生效（临时关防火墙即通），QQPC 驱动级防护 静默拦 TCP 入站（管理员无法停止/杀死）。阶段 2 前需落定长期方案： 端口级防火墙规则或换开发机。

# Phase 1 build chain: Rust .so -> jniLibs -> Gradle debug APK -> install -> launch

# Keep this file ASCII-only (PS 5.1 reads BOM-less .ps1 as GBK; see lessons).

# Usage (from apps/android-viewer/):

# powershell -ExecutionPolicy Bypass -File build-android.ps1 [-Host_ 192.168.1.5] [-Port 47800] [-Code t] [-SkipRust]

# Prereqs (Windows dev box):
|

# - Rust + Android targets + cargo-ndk + NDK (see personal docs/baseline.md toolchain table)
|
|
# - JDK 17 + Gradle 8.14 (paths in $vars below, adjust to your machine)
|
|
# - local.properties with sdk.dir (gitignored; template: sdk.dir=<android sdk path>)
