+# Android 端显示 “Not Found” 排查计划（TodoList.Maui）
+
+## 目标
+
+- 找出 Android 模拟器里只显示 `Not Found` 的根因（是 Web 资源缺失、内嵌 Web Server 路由/解析问题，还是 WebView 加载了错误地址）
+- 给出可验证的修复方案，并确保修复后能在 Android 上正常加载前端页面
+
+## 背景（当前实现快速定位）
+
+- Android 使用自建 TCP HTTP Server，静态资源从 APK 的 `Assets/wwwroot/*` 读取：[MobileEmbeddedWebServerService](file:///d:/Proj/TodoList/src/TodoList.Maui/Platforms/Android/MobileEmbeddedWebServerService.cs)
+- WebView 默认加载内嵌服务器地址（`IsUsingStatic=true` 时）：[MainPage.xaml.cs](file:///d:/Proj/TodoList/src/TodoList.Maui/Views/MainPage.xaml.cs)
+- Android 端静态文件找不到时返回纯文本 `Not Found`：[HandleStaticAsync](file:///d:/Proj/TodoList/src/TodoList.Maui/Platforms/Android/MobileEmbeddedWebServerService.cs#L214-L255)
+
+## 排查顺序（从“最可能 & 最省时间”到“深入原因”）
+
+### 1) 确认 WebView 实际加载的 URL
+
+- 在 Android Debug 输出里确认 WebView Source（期望是 `http://localhost:5057` 或 `http://localhost:5057/`）
+- 如果不是内嵌地址，检查 `appsettings.json` 的 `WebServer.IsUsingStatic` 与 `ForEndUrl` 配置：[appsettings.json](file:///d:/Proj/TodoList/src/TodoList.Maui/appsettings.json)
+
+判定：
+- 若加载的是内嵌地址 → 继续第 2 步
+- 若加载的是外部地址（ForEndUrl）→ 重点查 ForEndUrl 对应服务是否启动/路由是否正确
+
+### 2) 确认前端 dist 是否存在且可用于打包
+
+- 检查 `src/TodoList.Web/dist/index.html` 是否存在
+- 如果不存在：在 `src/TodoList.Web` 下执行 `npm ci` + `npm run build`，确保产物生成
+
+判定：
+- dist 不存在/为空 → “Not Found”高概率来自 Android 静态资源根本没被构建或没被打进 APK
+
+### 3) 确认 Android APK 内是否真的包含 `Assets/wwwroot/index.html`
+
+- 重点验证打包结果是否存在：
+  - `assets/wwwroot/index.html`
+  - `assets/wwwroot/assets/*`（至少有 js/css）
+- 项目里通过 MSBuild 目标把 `TodoList.Web/dist` 映射为 AndroidAsset（Link 到 `wwwroot/...`）：[TodoList.Maui.csproj](file:///d:/Proj/TodoList/src/TodoList.Maui/TodoList.Maui.csproj#L150-L175)
+
+判定：
+- APK 内没有 `wwwroot/index.html` → 修复构建/打包流程（第 6 步会给方案）
+- APK 内有 `wwwroot/index.html` → 继续第 4 步
+
+### 4) 记录 Android 内嵌服务器的“收到的请求 Path”与“找不到的 assetPath”
+
+目的：判断是否是“请求行解析不兼容”或“路径格式异常”导致找不到资源。
+
+- 在 `ReadRequestAsync`、`HandleStaticAsync` 临时输出：
+  - requestLine / target / path
+  - 计算出的 assetPath
+  - TryOpenAsset 失败的 assetPath
+
+高频根因候选：
+- WebView 请求行使用 absolute-form（例如 `GET http://localhost:5057/ HTTP/1.1`），当前解析逻辑会把整个 URL 当作 path，最终拼成无效 `wwwroothttp://...`，导致 404
+
+### 5) 排除 WebView/网络限制类问题（只在必要时做）
+
+- 如果看到的不是纯文本 `Not Found`，而是加载错误/空白：
+  - 检查 Android 明文 HTTP（`http://localhost`）是否被允许
+  - 检查 `network_security_config.xml` 与 Manifest 配置：[network_security_config.xml](file:///d:/Proj/TodoList/src/TodoList.Maui/Platforms/Android/Resources/xml/network_security_config.xml)、[AndroidManifest.xml](file:///d:/Proj/TodoList/src/TodoList.Maui/Platforms/Android/AndroidManifest.xml)
+
+### 6) 修复与验证（根据前面判定选择）
+
+#### A. 资源缺失/未打包
+
+- 让构建流程更“硬性”：
+  - 若 dist 不存在则强制构建，或在 Debug 也保证 `AndroidAsset` 包含 dist
+  - 可选：把 dist 复制进 `TodoList.Maui/wwwroot` 再用 `<Content Include="wwwroot\**" />`/`<MauiAsset />` 统一打包（减少条件目标的不确定性）
+
+验证：
+- APK 内能看到 `assets/wwwroot/index.html`，启动后不再返回 `Not Found`
+
+#### B. 请求路径解析不兼容（absolute-form 等）
+
+- 改进 `ReadRequestAsync`：当 target 是 `http(s)://...` 时解析出其中的 Path + Query，再走现有逻辑
+
+验证：
+- 记录到的 path 变为 `/` 或 `/index.html`，能成功打开 `wwwroot/index.html`
+
+#### C. 资源引用路径问题（js/css 请求 404）
+
+- 检查 dist 中 `index.html` 对 `assets/*` 的引用路径是否与 AndroidAsset 的 Link 一致
+- 若 Vite 输出含子目录（例如 `assets/chunks/...`），需要在 csproj 里用 `dist\**\*` 并保留 `%(RecursiveDir)`，避免扁平化导致引用断裂
+
+验证：
+- WebView 网络请求里 js/css 全部 200，页面正常渲染
+
+## 本次排查的“最短闭环”
+
+- 先确认 dist 是否存在 + APK 是否包含 `assets/wwwroot/index.html`
+- 若存在仍 Not Found，再用日志确认 requestLine/target/path 是否被解析成异常值（absolute-form 是最高优先级怀疑点）
+

+└─────────────────────────────────────┘
+```
+
+## 3. 功能需求
+
+### 3.1 核心功能：快速记录 (Quick Entry)
+- **全局快捷键**: 
+  - Windows: 允许用户注册/使用系统级全局快捷键（例如 `Ctrl + Alt + A`）
+  - macOS: 支持系统级快捷键（例如 `Cmd + Option + A`）
+  - 移动端: 通过通知快捷方式或小组件实现快速记录
+  - 支持在应用后台运行时响应快捷键
+- **快速唤起**: 
+  - 按下快捷键时，若应用最小化或隐藏，应立即弹出"新建任务"窗口或主界面
+  - 窗口弹出后，输入框应自动获取焦点，用户可直接打字
+
+### 3.2 任务模型 (Task Model)
+每个任务需包含以下核心字段：
+1. **任务名称 (Title/Content)**: 任务的具体描述
+2. **紧急程度 (Priority/Urgency)**: 
+   - 用于区分任务优先级（如：高、中、低）
+   - 需在界面上有直观的视觉区分（如颜色标记）
+3. **完成状态 (IsCompleted)**: 
+   - 标记任务是否已完成
+
+### 3.3 任务列表与视图 (Task List & View)
+- **列表展示**: 展示当前所有未完成的任务
+- **默认过滤**: 
+  - 应用启动或刷新时，**默认隐藏已完成的任务**
+  - (可选) 提供"显示已完成任务"的切换开关以便查看历史记录
+
+### 3.4 离线与同步 (Offline & Sync)
+- **离线记录**: 支持完全离线使用，数据优先保存于本地
+- **数据同步**: 在网络可用时（或特定时机），自动将本地数据同步到服务端（预留同步机制）
+
+### 3.5 跨平台适配需求
+- **响应式设计**: Vue.js 界面需适配不同平台的屏幕尺寸和分辨率
+- **平台特定功能**: 
+  - Windows: 利用 WebView2 特性，如文件访问、剪贴板等
+  - macOS: 遵循 macOS 设计规范
+  - 移动端: 支持触摸手势、通知等移动端特性
+- **原生功能集成**: 
+  - 通过 MAUI 调用平台原生 API
+  - WebView 与 C# 代码的双向通信
+
+### 3.6 UI设计原则
+- **紧凑设计**: UI界面需采用紧凑布局，减少不必要的留白和装饰元素，最大化信息展示空间
+- **高信息密度**: 在有限的屏幕空间内展示更多任务信息，提高用户浏览效率
+- **简洁高效**: 去除冗余的视觉元素，聚焦核心功能，让用户快速完成操作
+- **紧凑列表**: 任务列表项应采用紧凑的行高和间距，支持在单屏内显示更多任务
+- **精简控件**: 使用紧凑的按钮、图标和输入框，减少控件占用的空间
+- **高效布局**: 采用合理的网格或弹性布局，充分利用屏幕空间，避免大面积空白
+
+## 4. 非功能需求
+- **性能**: 
+  - 启动速度快，快捷键响应低延迟
+  - WebView 加载性能优化
+- **持久化**: 
+  - 任务数据需保存到本地（如 SQLite, JSON, 或 XML）
+  - 保证关闭应用后数据不丢失
+- **跨平台一致性**: 
+  - 各平台功能体验保持一致
+  - UI 界面风格统一
+- **兼容性**: 
+  - Windows: WebView2 运行时要求
+  - macOS: 系统版本要求
+  - 移动端: Android/iOS 最低版本要求
+
+## 5. 技术实现要点
+
+### 5.1 WebView 通信机制
+- **C# → Vue**: 通过 HTTP API 接口提供数据
+- **Vue → C#:** 通过 HTTP 请求调用 C# 后端接口
+- **数据序列化**: 使用 JSON 格式进行数据交换
+- **本地服务器**: C# 后端启动本地 HTTP 服务器（如 Kestrel）
+- **跨域处理**: 配置 CORS 支持跨域请求
+- **API 设计**: RESTful API 设计风格
+
+### 5.2 平台特定实现
+- **Windows**: 
+  - 使用 `Microsoft.Web.WebView2.Wpf` 或 MAUI 的 WebView2 控件
+  - 全局快捷键使用 Windows API
+- **macOS**: 
+  - 使用 `WKWebView` 
+  - 全局快捷键使用 AppKit API
+- **移动端**: 
+  - 使用平台原生 WebView
+  - 快速记录通过通知快捷方式实现
+
+### 5.3 构建与部署
+- **统一构建**: 使用 MAUI 单一项目构建多平台应用

+    tasks.value.filter(task => task.isCompleted)
+  );
+
+  // Actions
+  async function fetchTasks() {
+    loading.value = true;
+    try {
+      const response = await fetch('/api/tasks');
+      tasks.value = await response.json();
+    } catch (err) {
+      error.value = 'Failed to fetch tasks';
+    } finally {
+      loading.value = false;
+    }
+  }
+
+  return {
+    tasks,
+    loading,
+    error,
+    activeTasks,
+    completedTasks,
+    fetchTasks
+  };
+});
+```
+
+## 6. API 设计规范
+
+### 6.1 RESTful API 设计
+```csharp
+// 使用名词复数形式
+[HttpGet("tasks")]
+public async Task<ActionResult<List<Task>>> GetTasks()
+{
+}
+
+// 使用资源 ID
+[HttpGet("tasks/{id}")]
+public async Task<ActionResult<Task>> GetTask(int id)
+{
+}
+
+// 使用 HTTP 方法表示操作
+[HttpPost("tasks")]
+public async Task<ActionResult<Task>> CreateTask(CreateTaskDto dto)
+{
+}
+
+[HttpPut("tasks/{id}")]
+public async Task<ActionResult<Task>> UpdateTask(int id, UpdateTaskDto dto)
+{
+}
+
+[HttpDelete("tasks/{id}")]
+public async Task<ActionResult> DeleteTask(int id)
+{
+}
+```
+
+### 6.2 响应格式
+```csharp
+// 统一的响应格式
+public class ApiResponse<T>
+{
+    public bool Success { get; set; }
+    public T Data { get; set; }
+    public string Message { get; set; }
+    public List<string> Errors { get; set; }
+}
+
+// 成功响应
+return Ok(new ApiResponse<Task>
+{
+    Success = true,
+    Data = task,
+    Message = "Task created successfully"
+});
+
+// 错误响应
+return BadRequest(new ApiResponse<object>
+{
+    Success = false,
+    Message = "Validation failed",
+    Errors = new List<string> { "Title is required" }
+});
+```
+
+## 7. Git 提交规范
+
+### 7.1 提交信息格式
+```
+<type>(<scope>): <subject>
+
+<body>
+
+<footer>
+```
+
+### 7.2 Type 类型
+- `feat`: 新功能
+- `fix`: 修复 bug
+- `docs`: 文档更新
+- `style`: 代码格式调整（不影响代码运行）
+- `refactor`: 重构（既不是新功能也不是修复 bug）
+- `perf`: 性能优化
+- `test`: 测试相关
+- `chore`: 构建过程或辅助工具的变动
+
+### 7.3 示例
+```
+feat(api): add task completion endpoint
+
+- Add PATCH /api/tasks/{id}/complete endpoint
+- Update task service to handle completion logic
+- Add unit tests for completion functionality
+
+Closes #123
+```
+
+## 8. 测试规范
+
+### 8.1 单元测试
+```csharp
+// 测试类命名: ClassName + Tests
+public class TaskServiceTests
+{
+    [Fact]
+    public async Task GetTasksAsync_ReturnsAllTasks()
+    {
+        // Arrange
+        var mockRepository = new Mock<ITaskRepository>();
+        var service = new TaskService(mockRepository.Object);
+        
+        // Act
+        var result = await service.GetTasksAsync();
+        
+        // Assert
+        Assert.NotNull(result);
+        Assert.Equal(3, result.Count);
+    }
+}
+```
+
+### 8.2 集成测试
+```csharp
+public class ApiIntegrationTests : IClassFixture<WebApplicationFactory<Program>>
+{
+    private readonly HttpClient _client;
+
+    public ApiIntegrationTests(WebApplicationFactory<Program> factory)
+    {
+        _client = factory.CreateClient();
+    }
+
+    [Fact]
+    public async Task GetTasks_ReturnsSuccessAndCorrectContentType()
+    {
+        // Act
+        var response = await _client.GetAsync("/api/tasks");
+
+        // Assert
+        response.EnsureSuccessStatusCode();
+        Assert.Equal("application/json", response.Content.Headers.ContentType?.MediaType);

+
+## 技术实现细节
+
+### Windows 平台
+- 使用 `RegisterHotKey` 和 `UnregisterHotKey` Windows API
+- 支持全局快捷键监听
+- 通过 `WindowNative` 获取窗口句柄
+
+### macOS 平台
+- 使用 `NSEvent.AddGlobalMonitorForEventsMatchingMask` 监听全局事件
+- 支持 Command、Option、Control、Shift 等修饰键
+- 需要配置 `com.apple.security.automation.apple-events` 权限
+
+### 移动端
+- Android: 使用 `ShortcutManagerCompat` 创建通知快捷方式
+- iOS: 使用 `UIApplicationShortcutItem` 实现快捷操作
+
+### 数据持久化
+- 使用 `Microsoft.Maui.Storage.Preferences` 存储配置
+- JSON 序列化保存快捷键配置
+- 支持重置为默认配置
+
+## 依赖项
+
+### NuGet 包
+- `Microsoft.Maui.Controls`
+- `Microsoft.Extensions.DependencyInjection`
+- `Microsoft.Extensions.Logging.Debug`
+
+### 平台特定
+- Windows: `Microsoft.Windows.SDK.BuildTools`
+- macOS: `Microsoft.Maui.Controls.Compatibility`
+
+## 注意事项
+
+1. **macOS 权限**: 首次运行时需要在系统设置中授予辅助功能权限
+2. **Windows UAC**: 某些情况下可能需要管理员权限
+3. **移动端限制**: 移动端不支持真正的全局快捷键，使用通知快捷方式替代
+4. **WebView**: 确保 TodoList.Api 服务在 `http://localhost:5173` 运行
+
+## 后续计划
+
+- [ ] 添加 Linux 平台支持
+- [ ] 实现云同步功能
+- [ ] 添加更多快捷键功能
+- [ ] 优化性能和响应速度
+- [ ] 添加快捷键冲突检测
