+# 分布式数据对象多端协同 (DataObject)指南文档示例
+
+### 介绍
+
+
+本示例通过调用端拉起对端Ability后创建分布式数据对象并加入组网，被调用端被拉起后创建和恢复分布式数据对象。
+
+### 效果预览
+
+不涉及页面展示效果。
+
+### 使用说明
+
+1. 准备两台设备，一台作为发起端，一台作为接收端。
+
+2. 使用IDE自动签名，编译，安装（两台设备都需要安装）。
+
+3. 两台设备登录同一个华为账号，连接同一个wifi。
+
+4. 发起端设备保存数据到分布式数据对象，并将分布式数据对象同步给接收端设备，对端能够感知到数据变化。
+
+### 工程目录
+```
+entry/src/
+|   |--- main/
+|       |---ets/
+|           |---entryability/EntryAbility.ets   // 应用启动加载的入口ability
+|           |---entrybackupability/EntryBackupAbility.ets  // extensionAbility。
+|           |---pages/index.ets                 // entry主应用入口页面及接口调用实现
+```
+
+
+### 具体实现
+
+* 调用端调用startAbilityByCall接口拉起对端Ability：
+    
+    * 调用genSessionId接口创建一个sessionId，通过分布式设备管理接口获取对端设备networkId。
+
+    * 组装want，并将sessionId放入want。
+
+    * 调用startAbilityByCall接口拉起对端Ability。
+
+* 调用端拉起对端Ability后创建分布式数据对象并加入组网：
+    
+    * 创建分布式数据对象实例。
+
+    * 注册数据变更监听。
+
+    * 设置同步sessionId加入组网。
+
+* 被调用端被拉起后创建和恢复分布式数据对象：
+    
+    * 创建分布式数据对象实例。
+
+    * 注册数据变更监听。
+
+    * 从want中获取源端放入的sessionId，使用这个sessionId加入组网。
+
+
+### 相关权限
+
+ohos.permission.DISTRIBUTED_DATASYNC。
+
+### 依赖
+
+不涉及。
+
+### 约束与限制
+
+1.本示例仅支持标准系统上运行, 支持设备：RK3568。
+
+2.本示例为Stage模型，支持API20版本SDK，版本号：6.0.0.53，镜像版本号：OpenHarmony_6.0.0.53。
+
+3.本示例需要使用DevEco Studio 6.0.0 Release (Build Version: 6.0.0.858, built on September 5, 2025)及以上版本才可编译运行。
+
+### 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/DocsSample/ArkData/DataObject/CrossDeviceCollaboration > .git/info/sparse-checkout
+git remote add origin https://gitcode.com/openharmony/applications_app_samples.git
+git pull origin master

+# 分布式数据对象跨端迁移 (DataObject)指南文档示例
+
+### 介绍
+
+
+本示例通过迁移发起端创建分布式数据对象并保存数据到接收端，接收端创建分布式数据对象并注册恢复状态监听，实现跨设备数据迁移。
+
+### 效果预览
+
+不涉及页面展示效果。
+
+### 使用说明
+
+1. 准备两台设备，一台作为发起端，一台作为接收端。
+
+2. 使用IDE自动签名，编译，安装（两台设备都需要安装）。
+
+3. 两台设备登录同一个华为账号，连接同一个wifi。
+
+4. 发起端设备保存数据到分布式数据对象，并将分布式数据对象同步给接收端设备。
+
+### 工程目录
+```
+entry/src/
+|   |--- main/
+|       |---ets/
+|           |---entryability/EntryAbility.ets   // 应用启动加载的入口ability
+|           |---entrybackupability/EntryBackupAbility.ets  // extensionAbility。
+|           |---pages/index.ets                 // entry主应用入口页面及接口调用实现
+```
+
+
+### 具体实现
+
+* 迁移发起端在onContinue接口中创建分布式数据对象并保存数据到接收端：
+    
+    * 调用create接口创建并得到一个分布式数据对象实例。
+
+    * 调用genSessionId接口创建一个sessionId，调用setSessionId接口设置同步的sessionId，并将这个sessionId放入wantParam。
+
+    * 从wantParam获取接收端设备networkId，使用这个networkId调用save接口保存数据到接收端。
+
+* 接收端在onCreate和onNewWant接口中创建分布式数据对象并注册恢复状态监听：
+    
+    * 调用create接口创建并得到一个分布式数据对象实例。
+
+    * 调用genSessionId接口创建一个sessionId，调用setSessionId接口设置同步的sessionId，并将这个sessionId放入wantParam。
+
+    * 从wantParam获取接收端设备networkId，使用这个networkId调用save接口保存数据到接收端。
+
+### 相关权限
+
+不涉及。
+
+### 依赖
+
+不涉及。
+
+### 约束与限制
+
+1.本示例仅支持标准系统上运行, 支持设备：RK3568。
+
+2.本示例为Stage模型，支持API20版本SDK，版本号：6.0.0.53，镜像版本号：OpenHarmony_6.0.0.53。
+
+3.本示例需要使用DevEco Studio 6.0.0 Release (Build Version: 6.0.0.858, built on September 5, 2025)及以上版本才可编译运行。
+
+### 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/DocsSample/ArkData/DataObject/CrossDeviceMigration > .git/info/sparse-checkout
+git remote add origin https://gitcode.com/openharmony/applications_app_samples.git
+git pull origin master
