> 结合 `docs/android_app/session_state.md`(心跳)与 `docs/android_app/reverse_apk_features.md`(逆向总表)。
---
## 0. 给新模型的读取提示词
> 你是本项目的续任开发者。请先完整阅读 `C:\Project\MAG160C\docs\android_app\HANDOFF_DEVELOPMENT.md`
> 和 `C:\Project\MAG160C\docs\android_app\session_state.md`、`C:\Project\MAG160C\docs\android_app\reverse_apk_features.md`、
> `C:\Project\MAG160C\analysis\protocol_spec.md`,再继续开发。项目根目录 `C:\Project\MAG160C` 是 git 仓库,
> 源码在 `android\` 子目录(Gradle 工程,package `com.mag160c.thermal`)。当前会话状态与待办见 session_state.md。
---
## 1. 项目目标与背景
- 把 MAG160C 热像仪(160×120, 15fps, USB VID 0x833C)的官方 4 个安卓APP
(普通版 MAG-Cx / 专业版 MAG-Mx / ThermoScope 数据分析 / CoreSdkSample)逆向整合
为一款现代化安卓APP。
- 适配 **Android 16API 36**;用户反馈旧专业版在 Android 16 上花屏,重写根治。
- 逆向证据:`docs/android_app/reverse_apk_features.md`4 APP 功能总表)、
`analysis/protocol_spec.md`USB 协议/温度算法全逆向)。
- 用户要求:现代 UI、横竖屏自适应、**不建立流氓文件夹**(媒体→MediaStore DCIM/MAG160C)、
无 32 位库(纯 Kotlin,无 NDK)。
## 2. 技术栈与工具链(已部署)
- **纯 Kotlin + Jetpack Compose (Material 3)**,无 NDK、无 .so、无 native。
- Gradle 8.14.3`C:\Tools\gradle-8.14.3\bin\gradle.bat`),JDK Zulu 21`C:\Program Files\Zulu\zulu-21`)。
- Android SDK`C:\Users\ZXC\AppData\Local\Android\Sdk`platforms/android-36、build-tools 36.1.0、
platform-tools/adb、模拟器 system-images android-36.1 google_apis_playstore x86_64、AVD `Medium_Phone_API_36.1`)。
- 工程:`C:\Project\MAG160C\android\`;版本目录 `gradle\libs.versions.toml`
AGP 8.11.1 / Kotlin 2.2.0 / Compose BOM 2025.06.01 / lifecycle 2.9.1 / junit 4.13.2)。
- **磁盘轻量约定**:不装 NDK/CMake/zig(曾占用 2.4GB+,已卸载);全 Kotlin。
- 模拟器实测命令(无窗口):
```powershell
Start-Process "$env:LOCALAPPDATA\Android\Sdk\emulator\emulator.exe" -ArgumentList @('-avd','Medium_Phone_API_36.1','-no-window','-no-audio','-gpu','swiftshader_indirect') -WindowStyle Hidden

## 4. 核心知识(必须知道)
### 4.1 渲染管线(已逐字节验证)
- `core/RenderPipeline.kt` 移植自 `csdk/src/mag160c_render.c`(官方管线,像素级验证)。
- 输入:USB 帧(0x38 头 + 38400B u16 小端 + 尾部);输出 320×240 ARGB。
- FFC 状态机:暖机20帧内暂停;第75帧强制FFCFFC(0)→5隐藏→FFC(1)→4参考帧→4隐藏→正常。
- **移植陷阱(已解决,改代码时务必保持)**:
1. C 的 32 位无符号回绕:所有 `u32()` 掩码必须保留(cdf*denom、0xffc0000-iv7*0x40000、(v-lo)*S 等)。
2. lutRebuild 里 `u12` 的基址是常量 `iv7*0x10+0x10`**不是**链式 u21v。
3. ByteArray 存 255=-1:判 0xFF 必须 `(b.toInt() and 0xFF)`。
4. 暖机窗口检查在 ffc_step **之前**(顺序不能改)。
- 验证方式:`android/app/src/test/.../RenderPipelineTest.kt`JVM 差分测试,参照 `analysis/render_offline.c` 的 C 输出,60帧序列与官方DDT)。
### 4.2 USB 协议(analysis/protocol_spec.md 全文)
- 命令:普通 4 字节 magicFFC 8 字节 {magic, param}。
- 初始化:66b→66c→66f4B)→FFC(0)×2→300ms→START(73);停止 STOP(74)。
- 帧流:EP 0x81 bulk0x1BB1B11B 头 + 0x1C 起像素 + 尾部 shutter 于 +0x24。
- 相机信息块 0x5BB5B55B+0x00 pid、+0x08 序列号、+0x10 宽、+0x14 高、+0x18 fps。
### 4.3 实时画面渲染(本轮设计约定)
- **图像恒旋转90°CW绘制为 3:4 竖向**,填满可用区域(顶栏下~底导航上),
**不随手机旋转**(手机怎么转图像区域都不动)。
- **文字/图标恒屏幕水平**(可读);标记文字位置自动跟随(probeToScreen 固定 90° 映射:
`fx=1-sy/120, fy=sx/160`)。
- 顶栏=控制项(FFC/变倍/追踪·开/调色板/拍照/录像/调色板名),恒在顶部,`safeDrawing` 顶部inset 适配挖孔屏。
- 底栏=导航恒在底部(横竖屏一致;**没有横屏左栏**)。
- 顶栏高度经 `onSizeChanged`→`vm.uiTopPx`;底导航高度经 `UiInsets.navPx`→`vm.uiBottomPx`,渲染器据此留白。
- 演示模式:无设备时用真实管线+DDT渲染合成帧(热块场景),demo温度用局部线性显示映射
(真机温度走管线数学;绝对温度标定待真机)。
### 4.4 温度
- 温度 = 毫度 int(÷1000 = ℃)。`counts_to_temp_mc`(NUC域→T2E逆映射)用于探针/OSD,
在真机上需按 DDT 标定核对绝对值(待办)。
- 离线 MDT 温度解码(ConvertResponse2Temperature + 标定参数)未实现(待真机文件对照)。
## 5. 构建 / 测试 / 提交
```powershell
# 构建(无 --daemon 单次,约1分钟)
cd C:\Project\MAG160C\android
$env:JAVA_HOME="C:\Program Files\Zulu\zulu-21"
& "C:\Tools\gradle-8.14.3\bin\gradle.bat" :app:assembleDebug --no-daemon
# 单元测试(管线差分验证)
& "C:\Tools\gradle-8.14.3\bin\gradle.bat" test --no-daemon
# 产物
Copy-Item app\build\outputs\apk\debug\app-debug.apk C:\Project\MAG160C\build-artifacts\mag160c-app-debug.apk
# 提交(每里程碑一个 commit,不 push
git -C C:\Project\MAG160C add -A
git -C C:\Project\MAG160C commit -m "android: ..."
```
## 6. 严重教训(反复踩坑,务必遵守)
1. **编码**:所有源码必须 UTF-8。本机默认编码是 GBK!
- **python 读写文件必须显式 `encoding='utf-8'`**`open(p,'w')` 裸写会变 GBK→编译出的中文全乱码)。
- 检测/修复脚本:`C:\Users\ZXC\AppData\Local\Temp\opencode\fix_encoding.py`、
`check_mojibake.py`。改完必须跑一遍确认全 OK,再构建。
- gradle.properties 已有 `-Dfile.encoding=UTF-8`gradle + kotlin daemon)。
2. **图标**:手写 pathData 的弧线易坏,一律用双弧圆 `M x,y a r,r 0 1,0 2r,0 a r,r 0 1,0 -2r,0z` + 直线/矩形。
3. **SurfaceView 与旋转**:不要在横竖屏间切换不同布局分支(SurfaceView 会被销毁且 surface 不重建)。
用"稳定单分支 + 覆盖层"布局(当前实现即如此)。
4. **写代码要谨慎**:本会话多次因急于成稿写出语法错误/残留死代码。每写一个文件后立即编译。
## 7. 当前状态与待办
**已完成**:核心管线移植(字节级验证)、USB 层、实时画面(竖图固定+顶栏控制+底栏导航+
圆圈标记+大色标+演示模式)、拍照 MDT 容器→MediaStore、MP4 录像、媒体库、离线分析查看器、
PDF 报告、任务解析、设置页、Android16 沉浸(状态栏隐藏+挖孔适配+fullSensor)、乱码多次修复。
**待办**(记录在 session_state.md):
1. 真机 USB 实测:温度绝对值标定、FFC/录像/MDT 保存端到端。
2. 网络互连远程预览(用户需求:UDP 自动发现 + 手动内网 IP 连另一台插热像仪的手机)。
3. 离线 MDT 温度解码(ConvertResponse2Temperature + 标定参数)。
4. 厂商 12 调色板精确提取(运行时抓取或逆向)。
5. 可见光 PIP 融合、云模块(预留结构)。

encoding='utf-8';本次 LiveScreen.kt 双重乱码已重写恢复,dex 验证 CJK 正常
- [x] 模拟器验证:顶栏/左导航/图像/色标/标记布局正确,中文正常,状态栏隐藏生效
## 用户反馈修复 第四轮(2026-09-07,最终布局约定)
- [x] **顶栏/底栏位置固定**:顶栏=控制项(FFC/变倍/追踪/调色板/拍照/录像)恒在顶部;
底栏=导航恒在底部。横竖屏都不移动(**取消横屏左栏**),图标文字跟随屏幕方向(恒可读)
- [x] **图像区域永不旋转**:图像恒 90°CW 绘制为 3:4 竖向,填满顶栏~底栏之间可用区,
手机怎么转都不动;只转标记文字(文字恒屏幕水平,位置经 probeToScreen 固定90°映射)
- [x] **顶栏适配挖孔屏**`WindowInsets.safeDrawing.only(Top)` 顶部安全区 padding
- [x] 去掉 display-rotation 依赖(uiRotation/drawRotationDeg 已删,tapImage/probeToScreen
用固定 90° 映射)
- [x] 完整交接文档:docs/android_app/HANDOFF_DEVELOPMENT.md(含给新模型的读取提示词)
