Feat: Android client Phase 0-3 full implementation

Feat: Sub-license count limit - LicenseLimit field in licenses.ini + context menu
- Add LicenseLimit field to LicenseInfo struct (0 = not set, unlimited) - Add GetLicenseLimit/SetLicenseLimit: read/write LicenseLimit key in licenses.ini - Append |lic:N to reserved field in TOKEN_AUTH response only when LicenseLimit > 0; absent |lic: means no limit (client defaults to 9999), so super admin authenticating to its own server is never falsely terminated - Add "Sub-license limit" item in CLicenseDlg right-click menu (1-9999, empty = clear limit); menu label shows current value in real time - Limit change takes effect when sub-client re-authenticates Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

-## 免责声明
+## 本版本亮点：全平台闭环
-**请在使用本软件前仔细阅读以下声明：**
+本项目长期以 **C++ MFC 主控**（`YAMA.exe`）为核心交付形态——经典 Gh0st 架构、IOCP 高性能内核、完整的远程桌面 / 文件 / 进程 / 媒体功能栈、多层授权体系、品牌定制——**至今仍是主要使用的主控**。MFC 主控内置了基于 WebSocket 的 Web 远程桌面服务，从 v1.3.1 起就已经支持**任意平台的浏览器**远控被管设备（手机/平板/Linux/macOS 桌面均可）。
-1. **合法用途**：本项目仅供合法的技术研究、学习交流和授权的远程管理使用。严禁将本软件用于未经授权访问他人计算机系统、窃取数据、监控他人隐私等任何违法行为。
+本版本（v1.3.4）补上了最后一块拼图——**Go 主控**：一个**功能简单、聚焦于"远程桌面 + 远程终端 + 多用户分级"** 的轻量服务端，跨 Windows / Linux / macOS 编译运行。它的定位**不是替代 MFC**，而是为那些**不便于跑 Windows VPS** 的用户提供一个原生的 Linux/macOS 主控落点——例如纯 Linux 服务器、ARM Mac 长驻、嵌入式主控箱等场景。
-2. **使用者责任**：使用者必须遵守所在国家/地区的法律法规。因使用本软件而产生的任何法律责任，由使用者自行承担。
+### 两种主控形态如何选择
-3. **无担保声明**：本软件按"现状"提供，不附带任何明示或暗示的担保，包括但不限于适销性、特定用途适用性的担保。
+| 形态 | GUI | 功能覆盖 | 平台 | 定位 |
 |---|---|---|---|---|
 | **C++ MFC 主控** (`YAMA.exe`) | 原生 Windows GUI + 内置 Web 服务 | ✅ **全部功能** | Windows | **主推方案**。日常运维、文件管理、媒体采集、多层授权、品牌定制等都用它 |
 | **Go 主控**（新） | Web UI（任何浏览器） | 远程桌面 + 远程终端 + 多用户 | Windows / Linux / macOS | **补充方案**。需要"零 Windows 依赖"的纯 Linux/macOS 主控部署 |
-4. **免责条款**：开发者不对因使用、误用或无法使用本软件而造成的任何直接、间接、偶然、特殊或后果性损害承担责任。
+> [!TIP]
 > 两种主控**用的是同一套客户端**——可以混搭，例如一台 Windows MFC 主控 + 一台 Linux Go 主控并行管理同一批设备群。
-5. **版权声明**：本项目采用 MIT 协议开源，允许自由使用、修改和分发，但必须保留原始版权声明。
+### Go 主控的核心能力（v1.3.4 新增）
-**继续使用本软件即表示您已阅读、理解并同意上述所有条款。**
+- **远程桌面**：H.264 流通过 WebSocket 直发浏览器，WebCodecs 硬解，1080P @ 20fps 流畅
 - **远程终端**：xterm.js + ConPTY/PTY，支持调整尺寸、Tab 补全
 - **多用户体系**：管理员 / 普通用户分级、Challenge-Response 登录、不透明 token、按设备组授权
 - **生产部署**：Nginx 反代 + Let's Encrypt + Keyboard Lock + 全屏控制、防止 ESC / F11 误退出
 - **故意保持轻量**：不包含文件管理、媒体采集、注册表、服务管理等 MFC 主控专属功能——这些请走 MFC 主控
 ### 全平台支持矩阵
 |  | **客户端 (受控端)** | **主控端** |
 |---|---|---|
 | **Windows** | ✅ 完整功能 | ✅ MFC `YAMA.exe`（推荐）/ Go |
 | **Linux** (X11) | ✅ 屏幕 + 终端 + 文件 + 剪贴板 | ✅ Go |
 | **macOS** (Intel + Apple Silicon) | ✅ 屏幕 + 终端 + 文件 + 剪贴板 | ✅ Go |

-## 免責聲明
+## 本版本亮點：全平台閉環
-**請在使用本軟件前仔細閱讀以下聲明：**
+本專案長期以 **C++ MFC 主控**（`YAMA.exe`）為核心交付形態——經典 Gh0st 架構、IOCP 高效能核心、完整的遠端桌面 / 檔案 / 程序 / 媒體功能堆疊、多層授權體系、品牌客製化——**至今仍是主要使用的主控**。MFC 主控內建了基於 WebSocket 的 Web 遠端桌面服務，從 v1.3.1 起就已經支援**任意平台的瀏覽器**遠控被管裝置（手機 / 平板 / Linux / macOS 桌面均可）。
-1. **合法用途**：本專案僅供合法的技術研究、學習交流和授權的遠端管理使用。嚴禁將本軟件用於未經授權存取他人電腦系統、竊取資料、監控他人隱私等任何違法行為。
+本版本（v1.3.4）補上了最後一塊拼圖——**Go 主控**：一個**功能簡潔、聚焦於「遠端桌面 + 遠端終端 + 多使用者分級」** 的輕量伺服端，跨 Windows / Linux / macOS 編譯執行。它的定位**不是取代 MFC**，而是為那些**不方便執行 Windows VPS** 的使用者提供原生的 Linux / macOS 主控落腳點——例如純 Linux 伺服器、ARM Mac 長駐、嵌入式主控盒等情境。
-2. **使用者責任**：使用者必須遵守所在國家/地區的法律法規。因使用本軟件而產生的任何法律責任，由使用者自行承擔。
+### 兩種主控形態如何選擇
-3. **無擔保聲明**：本軟件按「現狀」提供，不附帶任何明示或暗示的擔保，包括但不限於適銷性、特定用途適用性的擔保。
+| 形態 | GUI | 功能覆蓋 | 平台 | 定位 |
 |---|---|---|---|---|
 | **C++ MFC 主控** (`YAMA.exe`) | 原生 Windows GUI + 內建 Web 服務 | ✅ **全部功能** | Windows | **主推方案**。日常運維、檔案管理、媒體擷取、多層授權、品牌客製化等都用它 |
 | **Go 主控**（新） | Web UI（任何瀏覽器） | 遠端桌面 + 遠端終端 + 多使用者 | Windows / Linux / macOS | **補充方案**。需要「零 Windows 依賴」的純 Linux / macOS 主控部署 |
-4. **免責條款**：開發者不對因使用、誤用或無法使用本軟件而造成的任何直接、間接、偶然、特殊或後果性損害承擔責任。
+> [!TIP]
 > 兩種主控**使用同一套用戶端**——可以混搭，例如一台 Windows MFC 主控 + 一台 Linux Go 主控並行管理同一批裝置群。
-5. **版權聲明**：本專案採用 MIT 協議開源，允許自由使用、修改和分發，但必須保留原始版權聲明。
+### Go 主控的核心能力（v1.3.4 新增）
-**繼續使用本軟件即表示您已閱讀、理解並同意上述所有條款。**
+- **遠端桌面**：H.264 流透過 WebSocket 直接推送瀏覽器，WebCodecs 硬體解碼，1080P @ 20fps 流暢
 - **遠端終端**：xterm.js + ConPTY/PTY，支援調整尺寸、Tab 自動補全
 - **多使用者體系**：管理員 / 一般使用者分級、Challenge-Response 登入、不透明 token、按裝置群授權
 - **生產部署**：Nginx 反向代理 + Let's Encrypt + Keyboard Lock + 全螢幕控制，防止 ESC / F11 誤退出
 - **刻意保持輕量**：不包含檔案管理、媒體擷取、登錄檔、服務管理等 MFC 主控專屬功能——這些請走 MFC 主控
 ### 全平台支援矩陣
 |  | **用戶端 (受控端)** | **主控端** |
 |---|---|---|
 | **Windows** | ✅ 完整功能 | ✅ MFC `YAMA.exe`（推薦）/ Go |
 | **Linux** (X11) | ✅ 螢幕 + 終端 + 檔案 + 剪貼簿 | ✅ Go |
 | **macOS** (Intel + Apple Silicon) | ✅ 螢幕 + 終端 + 檔案 + 剪貼簿 | ✅ Go |

 # YAMA 使用方法与技巧
 ## 编译程序
 编译此程序需要Visual Studio 2019及以上版本。如果编译Go服务端，需要Go 1.25及以上版本。
 除了直接通过Visual Studio打开项目文件进行编译，也可以通过以下命令进行编译:
 - build.cmd: 编译YAMA.exe（自动提前编译客户端程序）
 - build.cmd publish：编译YAMA.exe且通过upx压缩，所生成的可执行文件较小。
 - buld.cmd server：只编译YAMA.exe，需保证所依赖的客户端程序已经编译。
 - build.cmd go-server：编译 Go 服务端，可以选择带publish 参数进行upx压缩。
 ## Go 服务端
 支持在Windows、Linux、MacOS系统运行，使得用户不再依赖Windows服务器来搭建远程控制系统，且部署Go服务端在Linux或MacOS具有更高安全性。
 但是用户仍然需要有一台Windows电脑，使用YAMA生成客户端程序。
 ## 生成客户端
 自版本v1.3.4起，不论是服务端/主控端，还是客户端/受管端，都支持在全平台运行（Windows、Linux、MacOS）。
 关于在生成客户端时怎么填参数，参考早期在 GitHub 的[文档](https://github.com/yuanyuanxiang/SimpleRemoter/wiki#生成参数)。
 此文档也许已经过时，但新文档没有准备好。因为生成客户端的逻辑没有改变，所以这篇文档仍然具有参考价值。
 ## 更新内嵌资源
 参看 "server\2015Remote\BuildDlg.cpp" 描述，YAMA作为一个功能强大的远程管理系统，内嵌了包含客户端、开源工具在内的10多个资源。
 较新版本的YAMA支持在不修改源代码、不重新编译的情况下，更新内嵌的这些资源。用户只需要在当前YAMA进程的目录下，增加res子目录，
 将资源命名为如下所述的名称即可。例如编译了新版本的 frpc.dll， 将其放到 res/frps.dll 位置即可，重启YAMA即会使用该磁盘上的资源。
 ```
 namespace ResFileName {
    // Ghost 主程序
    const char* GHOST_X86         = "ghost_x86.exe";
    const char* GHOST_X64         = "ghost_x64.exe";
    const char* GHOST_LINUX       = "ghost_linux";
    const char* GHOST_MACOS       = "ghost_macos";
    // TestRun 加载器
    const char* TESTRUN_X86       = "testrun_x86.dll";
    const char* TESTRUN_X64       = "testrun_x64.dll";
    // ServerDll
    const char* SERVERDLL_X86     = "serverdll_x86.dll";
    const char* SERVERDLL_X64     = "serverdll_x64.dll";
    // TinyRun
    const char* TINYRUN_X86       = "tinyrun_x86.exe";
    const char* TINYRUN_X64       = "tinyrun_x64.exe";
    // SCLoader (Shellcode加载器)
    const char* SCLOADER_X86      = "scloader_x86.bin";
    const char* SCLOADER_X64      = "scloader_x64.bin";
    const char* SCLOADER_X86_OLD  = "scloader_old_x86.bin";
    const char* SCLOADER_X64_OLD  = "scloader_old_x64.bin";
    // FRP 相关 (无架构区分，64位DLL)
    const char* FRPC_DLL          = "frpc.dll";
    const char* FRPS_DLL          = "frps.dll";
    // 工具
    const char* UPX_EXE           = "upx.exe";
    const char* RCEDIT_EXE        = "rcedit.exe";
 }
 ```
 ## 使用插件
 将64位的Windows DLL放到Plugins目录，主控程序会加载DLL，且可以通过在线主机的右键菜单，将DLL发送的目标主机执行。
 开发自定义插件需要遵循一些规范：https://simpleremoter.com/plugins
 ## 载荷分离
 通过设置 Web 端口（默认值8080），来开启Web远程桌面，且本机会提供文件下载服务。将文件放置于该目录，从外部访问链接即可下载。
 比如，生成服务端时，选择 Shellcode+AES, 开启文件下载，将载荷生成为单独的文件 "1.bin"，将此文件放置于Payloads 目录。
 访问 http://127.0.0.1:8080/payloads/1.bin 即可下载此载荷文件。如果本机具有公网IP，则127.0.0.1可替换为公网IP。在有公网IP的计算机开启Web功能，必须设置登录密码，否则存在安全风险。
 采用载荷分离方式生成的程序，只有7KB，运行此程序会下载载荷，解密载荷中的Shellcode并执行。加载器源代码见 client\SimpleSCLoader.c，采用了高级编程技巧，无导入函数。本项目不提供任何“面纱”保证，且使用场景只限技术研究和学习。
 ## Web 远程桌面
 通过设置 Web 端口（默认值8080），即开启Web远程桌面，在浏览器地址栏访问本机8080端口就进入Web远程桌面，默认的密码是admin。
 如果本机有公网IP，务必修改默认密码，设置为较复杂的密码，否则可能被别人登录。Web登录已做防护，连续3次输入错误密码会冻结。
 从外部访问Web远程桌面，需要域名和证书（浏览器H264解码硬性要求）；Web 远程桌面支持2个主机同时在线，如需突破此限制，请联系管理员。

 # Android 客户端开发计划书
 > 目标功能：屏幕浏览 + 操作控制（触控/键盘输入注入）
 > 参考实现：`linux/` 与 `macos/`，两者已验证的共用策略同样适用于 Android
 ---
 ## 一、代码复用分析
 ### 1.1 可 100% 直接复用（NDK 无改动）
 | 文件 | 用途 | 依赖 |
 |------|------|------|
 | `common/ikcp.c/.h` | KCP 可靠 UDP 传输 | 纯 C，无 OS 依赖 |
 | `common/aes.c/.h` | AES 加密 | 纯 C |
 | `common/commands.h` | 协议定义（全平台共享） | 无 |
 | `common/client_auth_state.h` | 认证状态机 | 无 |
 | `common/posix_net_helpers.h` | POSIX socket 辅助函数 | POSIX（Android NDK 支持） |
 | `common/sub_conn_thread.h` | 子连接线程 | POSIX |
 | `common/rtt_estimator.h` | RTT 估计器 | 无 |
 | `common/logger.h` | 日志 | 无 |
 | `common/locker.h` | 互斥锁 | `std::mutex` |
 | `common/FileTransferV2.h` | V2 文件传输协议 | 无 |
 | `common/xxhash.h` | xxHash 校验 | 纯头文件 |
 | `client/IOCPClient.cpp/.h` | TCP/KCP 连接管理（Linux 已复用） | POSIX socket |
 | `client/Buffer.cpp/.h` | 数据缓冲区 | 无 |
 | `client/sign_shim_unix.cpp` | 签名垫片（Linux/macOS 已复用） | `libsign.a` |
 ### 1.2 可参考逻辑、重新实现 Android 版本
 | 现有文件 | Android 对应实现 | 原因 |
 |----------|-----------------|------|
 | `linux/ScreenHandler.h` | `android/cpp/ScreenHandler.h` | 捕获 API 不同（MediaProjection vs X11） |
 | `macos/InputHandler.mm` | `ControlService.kt` + `main.cpp::DispatchControlEvent` | 注入方式不同（AccessibilityService vs CGEvent） |
 | `linux/SystemManager.h` | `android/cpp/SystemManager.cpp`（Phase 4） | 系统 API 不同 |
 | `macos/H264Encoder.mm` | Android MediaCodec 路径（Java 侧） | 硬件编码器 API 不同 |
 | `linux/main.cpp` | `android/cpp/main.cpp` | 参考连接逻辑，逐段移植 |
 ### 1.3 不复用（Windows 专属）
 - `client/ScreenCapturerDXGI.h`、`client/IOCPBase.h`、`client/ScreenSpy.cpp`（Windows GDI/DXGI）
 - `client/KeyboardManager.cpp`（SendInput API）
 - `client/KernelManager.cpp`、`client/ServicesManager.cpp`
 ---
 ## 二、技术选型
 ### 2.1 屏幕捕获
 **方案**：`MediaProjection` API（Android 5.0+）
 ```
 MediaProjection
  └── VirtualDisplay (Surface)
        └── MediaCodec (Surface input，零拷贝)
              └── H.264 NALU → JNI → C++ ScreenHandler → 网络发送
 ```
 - 无需 root，官方公开 API
 - 通过 `ForegroundService` + `FOREGROUND_SERVICE_MEDIA_PROJECTION` 维持后台运行
 - **实际采用零拷贝路径（Path A）**：VirtualDisplay 的 Surface 直接绑定 `MediaCodec` 输入 Surface，无 ImageReader 中间环节
 ### 2.2 视频编码
 **已采用**：Android `MediaCodec`（硬件 H.264 加速）✅
 - VirtualDisplay Surface → MediaCodec Surface input → H.264 NALU，零拷贝
 - 关键帧前自动拼接 SPS+PPS，确保解码器可初始化
 - 每 2 秒强制触发一次 IDR（兼容忽略 `KEY_I_FRAME_INTERVAL` 的软编码器）
 - 编码分辨率：长边限制 1080，保持宽高比，宽高各自 2 对齐（H.264 要求）
 **编码流水线**：
 ```
 VirtualDisplay → MediaCodec(Surface input) → CODEC_CONFIG(SPS/PPS) + IDR+P 帧
  → onOutputBufferAvailable → JNI nativeOnH264Frame → C++ g_screenHandlers (broadcast) → TCP
 ```
 ### 2.3 输入控制
 **已采用**：`AccessibilityService`（`ControlService.kt`）✅
 | 事件 | 映射 |
 | --- | --- |
 | `WM_LBUTTONDOWN/MOVE/UP` | 累积路径，UP 时判断：位移 < 10px → 单击（dispatchTap），否则 → 拖拽（dispatchTouchGesture） |
 | `WM_LBUTTONDBLCLK` | 双击：两次 80ms 手势，间隔 200ms |
 | `WM_RBUTTONDOWN` | 长按 600ms |
 | `WM_MOUSEWHEEL` | delta > 0（滚轮上）→ 手指下划 +400px；delta < 0 → 手指上划 -400px |
 | `WM_KEYDOWN` Backspace/ESC | `GLOBAL_ACTION_BACK` |
 | `WM_KEYDOWN` VK_HOME (0x24) | `GLOBAL_ACTION_HOME` |
 | `WM_KEYDOWN` VK_APPS (0x5D) | `GLOBAL_ACTION_RECENTS` |
 | `WM_KEYDOWN` PrtSc (0x2C) | `GLOBAL_ACTION_TAKE_SCREENSHOT` |
 **关键实现细节**：
 - 协议：`COMMAND_SCREEN_CONTROL` + MSG64（固定 48 字节），**坐标从 lParam（offset 24）读取**，与 Windows/Linux/macOS 客户端完全一致；不读 pt.x/pt.y（64-bit MSG 与 MSG64 的 pt 偏移不同，直接读会得到错误 Y 坐标）
 - 坐标映射：`phys = enc * physSize / encSize`（编码空间 → 物理屏幕空间）
 - 单击路径非退化：`moveTo(x,y); lineTo(x+1,y)`，避免 Android 静默拒绝零长度手势路径
 - C++ → Kotlin 回调：`DispatchControlEvent()` 全局函数通过 JNI AttachCurrentThread → `ControlService.onControlEvent(@JvmStatic)` → post 到主线程 Handler
 ### 2.4 网络传输
 与 Linux 完全相同的 POSIX socket 路径：
 - TCP 控制通道（`IOCPClient.cpp` 已在 Linux 验证）
 - KCP over UDP 视频流（`ikcp.c` 纯 C，NDK 直接编译，当前未启用）
 - TLS/AES 加密复用 `common/aes.c`

 ---
 ## 四、开发阶段
 ### Phase 0：工程初始化 ✅ 已完成
 - 创建 Android Studio 项目，配置 NDK + CMake
 - `CMakeLists.txt` 引入 `common/`、`client/` 源文件（与 `linux/CMakeLists.txt` 同构）
 - 编译验证 `IOCPClient.cpp + Buffer.cpp + sign_shim_unix.cpp + ikcp.c` 在 NDK 下无错误
 - `SimplePlugins/sign_lib/` 新增 `sha256_portable.h`（纯 C，零外部依赖）和 `build_android.sh`，在 WSL + NDK r27c 下成功交叉编译，产物已复制至 `android/app/src/main/cpp/lib/{arm64-v8a,armeabi-v7a}/libsign.a`
 ### Phase 1：连接与协议 ✅ 已完成
 - 移植 `linux/main.cpp` 的连接逻辑到 `android/cpp/main.cpp`
 - `CaptureService.kt` 通过 `YamaBridge.nativeInit()` 启动 C++ 网络线程
 - 实现登录握手（`LOGIN_INFOR`）、心跳（`TOKEN_HEARTBEAT` + `CMD_HEARTBEAT_ACK` RTT 估算）、认证状态机（`client_auth_state.h`）
 - 设备信息上报：ANDROID_ID（XXH64 作为 ClientID）、型号、OS 版本、分辨率
 - 心跳日志限流：60 秒最多打印一次，避免 logcat 刷屏
 ### Phase 2：屏幕捕获与编码 ✅ 已完成
 - `CaptureService.kt`：申请 `MediaProjection`，建立 `VirtualDisplay`，Surface 直连 `MediaCodec`
 - SPS/PPS 缓存，IDR 帧发送前自动拼接，子连接 `COMMAND_NEXT` 后开始推流
 - `ScreenHandler.h`：发送 `TOKEN_BITMAPINFO`（含 `ScreenSettings.QualityLevel=H264`），`SendH264` 封装帧头
 - 服务端 H264 解码器正常显示 Android 屏幕 ✅
 - 服务端适配：`ScreenSpyDlg.cpp` 新增 `ComputeAdaptiveLayout()` 自适应缩放和信箱黑边，`m_offsetX/Y` 修正坐标映射（已合入 `main` 分支）
 ### Phase 3：操作控制 ✅ 已完成（branch: feature/android-remote-control）
 - `ControlService.kt`（`AccessibilityService`）：手势注入、全局键、双击/长按/滚轮
 - `main.cpp::DispatchControlEvent()`：JNI 反向调用，将 `COMMAND_SCREEN_CONTROL` 路由到 Kotlin
 - `ScreenHandler.h::OnReceive`：子连接也可接收 `COMMAND_SCREEN_CONTROL`，统一调用 `DispatchControlEvent`
 - 坐标 Bug 修复：64-bit MSG 与 MSG64 的 `pt.x/pt.y` 偏移不同（MSG: offset 36，MSG64: offset 40）；改为从 lParam（两者均在 offset 24）提取坐标，与其他所有客户端保持一致
 - 单击无效 Bug 修复：零长度手势路径被 Android 静默拒绝；tap 改用 `lineTo(x+1, y)` 非退化路径
 - 代码审查修复：JNI `ExceptionClear()`
 ### Phase 3 后期修复 ✅ 已完成
 发现并修复的生产问题：
 | 问题 | 根因 | 修复文件 |
 |------|------|---------- |
 | 静止屏幕首帧黑屏 10-60 秒 | SurfaceFlinger 空闲优化：无脏区时不向 VirtualDisplay 推帧，`REQUEST_SYNC_FRAME` 永远排队等不到输入帧 | `CaptureService.forceFirstFrame()`：VirtualDisplay 临时 resize +2px 触发强制合成；`main.cpp` 在 `SendBitmapInfo` 后调用 `ForceFirstFrameFromJava()` |
 | 部分硬件编码器 IDR 帧未被识别 | 高通等 SoC 对强制 IDR 不设置 `BUFFER_FLAG_KEY_FRAME`，`SendLoop` 将其当作 P 帧丢弃，首帧永远发不出 | `CaptureService.isNaluKeyframe()`：扫描 Annex-B NALU type 5/7/8 补充判断 |
 | H.264 推流在 `SendBitmapInfo` 前卡住 | 推送模式下服务端 `COMMAND_NEXT` 到达时 `setManagerCallBack` 尚未注册消息被丢弃，`m_started` 永远为 `false` | `ScreenHandler.h::SendBitmapInfo()` 末尾直接 `m_started=true; m_cond.notify_all()` |
 | 多用户不能同时观看/控制 | `g_screenHandler` 单指针 + `g_screenSpyRunning` 互斥锁，只允许一条子连接 | `main.cpp`：改为 `std::set<AndroidScreenHandler*> g_screenHandlers`，`nativeOnH264Frame` 广播给全部 handler；每个 `COMMAND_SCREEN_SPY` 独立建立子连接，对齐 Windows/Linux/macOS 客户端行为 |
 ### Phase 4：系统信息与稳定性（进行中）
 **已完成：**
 | 功能 | 说明 |
 |------|------|
 | 活动窗口上报 | `ControlService` 监听 `TYPE_WINDOW_STATE_CHANGED`，通过 JNI `getActiveWindow()` 上报当前前台包名；锁屏时上报 `"Locked"` |
 | 心跳间隔下限 | Android 侧将服务端下发的 `ReportInterval` 强制限制为 `max(收到值, 30)`，防止 5s 高频心跳耗电 |
 | 服务端心跳超时延长 | `CheckHeartbeat()` 超时阈值从 `max(60, interval*3)` 改为 `max(120, interval*3)`，与 30s 心跳间隔留出 4 倍余量 |
 | CPU 频率上报 | `GetCpuMHz()` 优先读 `/sys/devices/system/cpu/*/cpufreq/cpuinfo_max_freq`，虚拟机无此节点时回退读 `/proc/cpuinfo` 的 `BogoMIPS` |
 | 后台保活 | `ForegroundService` + 持久通知（Phase 2 已完成），豁免 Doze 模式网络限制 |
 | 应用图标 | 自定义眼睛图标，支持 Android 8+ Adaptive Icon（前景层 + 浅灰背景），兼容各厂商形状裁切 |
 | Release 签名 | `yama-release.jks` 随仓库分发，密码通过 `YAMA_PWD` 环境变量或交互输入，保证多机一致签名 |
 **待完成：**
 - 处理 `MediaProjection` 被用户撤销的情况（弹出通知，引导重授权）
 - 连接断线自动重连后子连接同步重建（目前 `ScreenSpyThread` 有 20 次重试，但主连接重连后子连接未同步恢复）
 - `WM_MBUTTONDOWN`（中键）手势映射（目前静默丢弃）
 - `SystemManager` 封装：将 Java 层已上报的设备信息（型号、版本、IP）统一封装为独立模块
 ---
 ## 五、关键约束与风险
 | 风险 | 影响 | 状态 |
 |------|------|------|
 | ~~`libsign.a` 无 ARM 构建~~ | ~~Phase 0 阻塞~~ | ✅ 已解决：`sha256_portable.h` + `build_android.sh` |
 | Android 12+ `MediaProjection` 需每次重新申请 | 后台录屏被中断 | `ForegroundService` 保活 + 通知引导重授权 |
 | `AccessibilityService` 用户需手动开启 | 操作控制功能受限 | UI 引导流程，说明开启步骤 |
 | 某些厂商 ROM 限制后台 Service | 连接断开 | 电池优化白名单申请 |
 | H.264 Baseline Level 对齐 | 服务端解码兼容性 | `MediaCodec` 输出指定 `profile=Baseline`，与 x264 现有配置一致 |
 | `AccessibilityService` 无法向系统设置页面注入手势 | 设置界面无法远程操作 | Android 安全限制，无解，提示用户 |
 ---
 ## 六、代码审查注意事项
 ### 最高原则：既有功能无破坏
 增加 Android 客户端支持时，Windows/Linux/macOS 客户端的全部既有功能必须保持正常。每次改动上线前须验证：
 | 检查项 | 说明 |
 | --- | --- |
 | `isAndroidRemote` 初始值为 `false` | 非 Android 客户端走原有代码路径，不受影响 |
 | `updateUIForOrientation()` Android 分支有 `isAndroidRemote &&` 守卫 | 非 Android 客户端不会进入沉浸模式分支 |
 | `NotifyResolutionChange` 新参数有默认值 `= ""` | 现有调用点即便漏传也能正常编译和运行 |
 | `FindHostByClientID` 与 `FindHostByIP` 一致的指针返回约定 | ScreenSpyDlg 在 UI 线程（OnInitDialog）调用，OnReceiveComplete 在 IO 线程调用，后者读 `additonalInfo[]` 为只读操作，低概率竞争 |
 | Web 端坐标映射 `getTouchPos` 使用 `getBoundingClientRect()` | 动态取 canvas 实际显示尺寸，CSS 拉伸不影响坐标精度 |
 | Android 边缘手势检测有时间和距离双重门槛 | 普通慢速拖拽不会被误识别为系统手势 |
 ### 审查流程
 1. `git diff HEAD` 逐文件审查，重点关注非 Android 代码路径的改动
 2. 确认所有新增条件分支均以 `isAndroidRemote`、`client_type === 'APK'` 等 Android 专有标志守卫
 3. 共享协议结构体（`commands.h`、`LOGIN_INFOR`、`szReserved`）改动需确认向前/向后兼容
 4. 服务端 C++ 改动在 Windows 下编译，前端 `index.html` 在桌面和移动浏览器两端验证
 ---
 ## 七、不在本期范围
 - 音频监听（`AudioRecord` + Opus 编码）
 - 文件管理（已有 `FileTransferV2`，后期可直接接入）
 - 摄像头（前/后摄）
 - Shell 终端（`/system/bin/sh` + PTY，可参考 `PTYHandler.h`）
 - Root 特权功能（uinput、内核注入）

 # YAMA Android 客户端
 YAMA 的 Android 客户端，允许服务端将 Android 设备作为受控主机进行远程查看和操控。功能包括：
 - 屏幕实时截图并推流给服务端
 - 接收服务端的触控/按键指令并注入到系统
 - 后台保持心跳连接，支持长期驻留
 ---
 ## 编译前：配置服务端地址
 服务端 IP 和端口在源码中硬编码，编译前必须修改：
 文件：`app/src/main/java/com/yama/client/MainActivity.kt`
 ```kotlin
 private val serverIp   = "91.99.165.207"   // 改为你的服务端 IP
 private val serverPort = 443                // 改为你的服务端端口
 ```
 改完再执行编译，否则客户端连不上服务端。
 ---
 ## 编译环境
 在 **WSL（Ubuntu）或原生 Linux** 上编译，Windows 原生环境不支持。
 | 依赖 | 版本要求 | 安装命令 |
 |---|---|---|
 | Java | 17+ | `sudo apt install openjdk-17-jdk` |
 | CMake | 3.22+ | `sudo apt install cmake` |
 | Ninja | 任意 | `sudo apt install ninja-build` |
 | Android SDK | 含 build-tools | 见下方说明 |
 | Android NDK | 30.x（Linux 版） | 见下方说明 |
 ### Android SDK
 推荐通过 Android Studio 安装，安装后 SDK 默认在：
 - Windows：`%USERPROFILE%\AppData\Local\Android\Sdk`
 - Linux：`~/Android/Sdk`
 WSL 环境下脚本会自动检测 Windows 侧的 SDK，也可以手动指定：
 ```bash
 export ANDROID_HOME=/mnt/c/Users/<用户名>/AppData/Local/Android/Sdk
 ```
 ### Android NDK（Linux 版）
 > **重要**：必须使用 **Linux 版 NDK**，Windows NDK 的 `.exe` 工具无法在 WSL 内执行。
 ```bash
 # 下载 Linux NDK（约 600 MB）
 wget https://dl.google.com/android/repository/android-ndk-r30b-linux.zip
 unzip android-ndk-r30b-linux.zip -d $HOME
 # 解压目录名可能带字母后缀（r30、r30b 等），统一重命名
 mv $HOME/android-ndk-r30* $HOME/android-ndk
 ```
 脚本会自动检测 `~/android-ndk`，也可以通过环境变量指定：
 ```bash
 export ANDROID_NDK_HOME=$HOME/android-ndk
 ```
 ---
 ## 签名密钥（一次性准备）
 Release APK 需要签名密钥。密钥库文件 `yama-release.jks` 已在仓库中，**密码需向仓库维护者获取**，或通过以下方式传入：
 ```bash
 # 方式一：环境变量（推荐，避免每次输入）
 export YAMA_PWD=密钥库密码
 # 方式二：编译时脚本会交互提示输入
 ```
 如需重新生成密钥库（密码遗失等情况）：
 ```bash
 cd android/
 keytool -genkeypair -keystore yama-release.jks \
  -alias yama -keyalg RSA -keysize 2048 -validity 10000 \
  -dname 'CN=YAMA,O=Internal,C=CN'
 ```
 > 密钥库文件本身不含私密信息，可以提交到 git；密码不要提交。
 > 重新生成密钥库后，已安装旧版本的设备需要先卸载再安装。
 ---
 ## 编译
 在 WSL 或 Linux 终端中，进入 `android/` 目录：
 ```bash
 cd android/
 # 编译 Release（默认，约 1.7 MB，推荐部署用）
 ./build_apk.sh
 # 编译 Debug（约 4 MB，含调试符号，开发排查用）
 ./build_apk.sh debug
 # 清理所有编译产物（切换配置或遇到奇怪错误时使用）
 ./build_apk.sh clean
 ```
 编译成功后产物：
 | 类型 | 路径 |
 |---|---|
 | Release | `ghost.apk` |
 | Debug | `ghost-debug.apk` |
 ---
 ## 安装到设备
 ### 1. 传输 APK
 将 `ghost.apk` 拷贝到手机（USB 传输、微信文件传输等均可）。
 ### 2. 安装
 在手机上用文件管理器找到 APK，点击安装。
 如提示"禁止安装未知来源应用"，需先开启允许：
 - **Android 8+**：设置 → 应用 → 找到你使用的文件管理器 → 允许安装未知应用
 - **MIUI/ColorOS 等**：设置 → 隐私/安全 → 安装未知应用
 ### 3. 解除受限设置（Android 13+ 必须）
 Android 13 及以上系统对手动安装的 APK 有额外限制，若不解除，无法授权 Accessibility Service：
 1. 打开 **设置 → 应用 → YAMA**
 2. 点击右上角 **三点菜单**
 3. 选择 **"允许受限设置"**（Allow restricted settings）
 4. 使用 PIN 或指纹确认
 > 此步骤每次重新安装 APK 后都需要重复执行一次。
 ### 4. 授权必要权限
 **Accessibility Service**（必须，用于注入触控/按键）
 设置 → 无障碍 → 已安装的应用 → YAMA → 开启
 > 重装 APK 后此权限会被重置，需重新授权。
 ### 5. 启动
 点击桌面 YAMA 图标启动，系统会弹出屏幕录制确认框，点击 **"立即开始"** 授权。
 授权后应用进入后台运行，通知栏会显示一条持久通知表示服务正在运行。此后服务端即可在主机列表中看到该设备。
 > 屏幕录制确认在每次应用重启后都会弹出，这是 Android 系统的强制要求，无法跳过。
 ---
 ## 注意事项
 - 建议在电池优化设置中将 YAMA 设为 **"不限制"**（或"不优化"），防止系统在后台将其杀掉
  - 路径：设置 → 应用 → YAMA → 电池 → 不限制
 - 心跳间隔最小 30 秒，长期后台运行耗电量与微信后台相当
 - 服务端可在设置中调大上报间隔（建议不超过 60 秒）以进一步降低耗电

 #
 #   Gradle start up script for POSIX generated by Gradle.
 #
 #   Important for running:
 #
 #   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
 #       noncompliant, but you have some other compliant shell such as ksh or
 #       bash, then to run this script, type that shell name before the whole
 #       command line, like:
 #
 #           ksh Gradle
 #
 #       Busybox and similar reduced shells will NOT work, because this script
 #       requires all of these POSIX shell features:
 #         * functions;
 #         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
 #           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
 #         * compound commands having a testable exit status, especially «case»;
 #         * various built-in commands including «command», «set», and «ulimit».
 #
 #   Important for patching:
 #
 #   (2) This script targets any POSIX shell, so it avoids extensions provided
 #       by Bash, Ksh, etc; in particular arrays are avoided.
 #
 #       The "traditional" practice of packing multiple parameters into a
 #       space-separated string is a well documented source of bugs and security
 #       problems, so this is (mostly) avoided, by progressively accumulating
 #       options in "$@", and eventually passing that to Java.
 #
 #       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
 #       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
 #       see the in-line comments for details.
 #
 #       There are tweaks for specific operating systems such as AIX, CygWin,
 #       Darwin, MinGW, and NonStop.
 #
 #   (3) This script is generated from the Groovy template
 #       https://github.com/gradle/gradle/blob/HEAD/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
 #       within the Gradle project.
