+ * 功能描述: 多文件下载监听在应用开发中是一个非常常见的需求。本示例将介绍如何使用request上传下载模块实现多文件下载监听，如监听每个文件下载任务的进度，任务暂停，下载完成等下载情况。
+ *         每个应用最多支持创建10个未完成的任务，相关规格说明请参考request.agent.create。
+ *
+ * 推荐场景: 多文件下载
+ *
+ * 核心组件:
+ * 1. FileDownloadItem
+ *
+ * 实现步骤：
+ * 1.配置下载参数。一个下载任务需要配置对应一套下载参数request.agent.Config。本例中使用downloadConfig方法简单配置了下载文件的url，实际业务
+ * 中请按实际情况按需配置。
+ * 2.创建多个文件下载监听实例。单个文件下载监听只需要配置下载参数，创建下载任务，注册下载任务相关监听，启动下载任务即可实现。而要实现多文件下载监听，
+ * 需要每个下载任务注册独立的下载监听回调。本例通过封装自定义组件FileDownloadItem，在每个FileDownloadItem中创建各自的下载任务和监听回调，从
+ * 而实现多文件下载监听。
+ * 3.创建下载任务，并注册下载任务相关监听。本例在每个FileDownloadItem中使用request.agent.create创建下载任务。然后在下载任务创建成功后，注
+ * 册各自下载任务相关监听。本例中注册了下载任务完成回调，下载任务失败回调，下载进度更新回调，暂停任务回调，重新启动任务回调。
+ * 4.启动下载任务。本例在每个FileDownloadItem中使用task.start方法启动各自的下载任务。
+ * 5.本例中下载任务用到的其他操作：使用request.agent.show，根据任务id可查询任务的详细信息。使用task.pause可以暂停正在等待WAITING/正在运行
+ * RUNNING/正在重试RETRYING的后台下载任务。使用task.resume可以重新启动任务，可恢复暂停的后台任务。

+# 网络场景
+
+### 介绍
+多任务依赖，要在完成任务A和完成任务B之后，才会唤醒任务C。
+
+**使用说明**
+1. 用户点击"启动所有任务"按钮
+2. 任务A和B同时开始执行
+3. 任务A完成后：
+    - 进度条更新至100%
+4. 任务B完成后：
+    - 进度条更新至100%
+    - 任务锁被释放
+5. 任务C检测到锁已释放，开始执行：
+    - 进度条开始增长
+6. 任务C完成后：
+    - 进度条更新至100%
+
+### 工程结构&模块类型
+   ```
+   entry/src/main/ets/
+|---pages
+|   |---taskDependencies.ets                    // 任务依赖
+|   |---index.ets                              // 首页(UI)
+   ```
+
+### 具体实现
+*初始状态*：
+- 任务锁 `lock` 设置为 `true`（锁定状态）
+- 任务A和B完成状态均为 `false`
+
+2. **任务执行过程**：
+    - 任务A和B并行执行
+    - 当任务A完成时，调用 `completeTaskA()` 方法：
+        - 设置 `taskACompleted = true`
+        - 更新进度
+        - 检查是否可以解锁
+    - 任务B同理
+
+3. **解锁条件**：
+    - 只有当任务A和B都完成且锁处于锁定状态时才会解锁
+
+4. **任务C触发**：
+    - 当锁被释放（`lock = false`）时执行任务C
+
+### 进度管理
+
+1. **进度分配**：
+    - 任务A完成：100%
+    - 任务B完成：100%
+    - 任务C完成：100%
+
+2. **进度更新**：
+    - 每次任务完成时增加相应进度
+
+### UI组件说明
+
+1. **进度条组件**：
+    - 使用ArkTS的`Progress`组件
+    - 线性样式直观展示进度变化
+    - 实时显示百分比数值
+
+2. **控制按钮**：
+    - "启动所有任务"：触发整个任务流程
+
+### 相关权限
+
+网络权限: ohos.permission.INTERNET
+
+### 依赖
+
+无
+
+### 约束与限制
+
+1. 本示例仅支持标准系统上运行，支持设备：Phone;
+2. 本示例为Stage模型，支持API20版本SDK，SDK版本号(API Version 20),镜像版本号(6.0.0.31)。
+3. 本示例需要使用DevEco Studio 版本号(6.0.0.6)版本才可编译运行。
+
+### 下载
+
+如需单独下载本工程，执行如下命令：
+
+```
+git init
+git config core.sparsecheckout true
+echo code/ArkTS1.2/NetworkSample/ > .git/info/sparse-checkout
