+# 网络场景
+
+### 介绍
+网络访问多任务依赖，完成任务A和B后，触发任务C
+
+### 效果图预览
+| 开启任务前                                                    |  
+|----------------------------------------------------------|
+| ![main](entry/src/main/resources/base/media/network.png) |
+
+**使用说明**
+1. 点击蓝色按钮"启动所有任务"
+2. 任务A或者任务B先开始运行，按钮切换到不可用状态
+3. 任务A和任务B执行完成之后，进度条进度为100%
+4. 开始执行任务C，任务C执行完成之后，进度条进度为100%，按钮切换到可用状态
+
+
+### 工程结构&模块类型
+
+   ```
+   entry/src/main/ets/
+|---pages
+|   |---index.ets                                     // 首页
+   ```
+
+### 具体实现
+
+* 网络任务依赖
+    *  点击蓝色按钮"启动所有任务"后执行函数startAllTasks()
+	*  在startAllTasks()函数中执行任务A和任务B，执行完成后将this.taskACompleted和this.taskBCompleted赋值为true，将this.lock解锁，赋值为false
+	*  每隔200ms判断this.lock的值，false为解锁状态可以执行任务C
+	*  执行任务C，清除延时器
+
+
+### 相关权限
+
+无
+
+### 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(6.0.0.21)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
+git remote add origin https://gitee.com/openharmony/applications_app_samples.git
