 # 跨端迁移
 
-
 ## 功能描述
 
 跨端迁移的主要工作是实现将应用当前任务（包括页面控件状态变量等）迁移到目标设备，能在目标设备上接续。主要功能包括：
 
 - 支持用户自定义数据存储及恢复。
-
 - 支持页面路由信息和页面控件状态数据的存储及恢复。
-
 - 支持应用兼容性检测。
-
-- 支持应用根据实际使用场景动态设置迁移状态（默认迁移状态为ACTIVE激活状态）。如编辑类应用在编辑文本的页面下才需要迁移，其他页面不需要迁移，则可以通过[setMissionContinueState](../reference/apis/js-apis-inner-application-uiAbilityContext.md#uiabilitycontextsetmissioncontinuestate10)进行控制。

+## 迁移功能可选配置
+
+### 1.动态配置迁移能力
+
+从API 10 起，提供了支持动态配置迁移能力的功能。即应用可以根据实际使用场景，在需要迁移功能时，设置开启应用迁移能力；在业务不需要迁移时，则可以关闭迁移能力。开发者可以通过调用[setMissionContinueState](../reference/apis/js-apis-inner-application-uiAbilityContext.md#uiabilitycontextsetmissioncontinuestate10)接口对迁移能力进行设置。默认状态下，可迁移应用的迁移能力为**ACTIVE**状态，即迁移能力开启，可以迁移。

+| 接口状态值                             | 含义                   |
+| :------------------------------------- | ---------------------- |
+| AbilityConstant.ContinueState.ACTIVE   | 应用当前可迁移能力开启 |
+| AbilityConstant.ContinueState.INACTIVE | 应用当前可迁移能力关闭 |
+
+**设置迁移能力的时机**
+
+迁移能力的改变可以根据实际业务需求和代码实现，发生在应用生命周期的绝大多数时机。本文介绍常用的几种配置方式。
+
+在ability的onCreate函数中调用接口，可以在应用创建时设置应用的迁移状态。
+
+```ts
+// EntryAbility.ets
+import UIAbility from '@ohos.app.ability.UIAbility';
+import AbilityConstant from '@ohos.app.ability.AbilityConstant';
+import Want from '@ohos.app.ability.Want';
+export default class EntryAbility extends UIAbility {
+  onCreate(want: Want, launchParam: AbilityConstant.LaunchParam): void {
+    // ...
     this.context.setMissionContinueState(AbilityConstant.ContinueState.INACTIVE, (result) => {
       console.info(`setMissionContinueState: ${JSON.stringify(result)}`);
     });
+    // ...
   }
-        ```
-    - 示例：应用在后续的业务流程中需要流转了
-
-        ```ts
-        import UIAbility from '@ohos.app.ability.UIAbility';
-        import AbilityConstant from '@ohos.app.ability.AbilityConstant';
-
+}
+```
+
+在页面的onPageShow函数中调用接口，可以设置单个页面出现时应用的迁移状态。
+
+```ts
+// PageName.ets
+import AbilityConstant from '@ohos.app.ability.AbilityConstant';
+import common from '@ohos.app.ability.common'
+@Entry
+@Component
+struct PageName {
+  private context = getContext(this) as common.UIAbilityContext;
+  build() {
+    // ...
+  }
+  // ...
+  onPageShow(){
+  // 进入该页面时，将应用设置为可迁移状态
     this.context.setMissionContinueState(AbilityConstant.ContinueState.ACTIVE, (result) => {
+      console.info('setMissionContinueState ACTIVE result: ', JSON.stringify(result));
+    });
+  }
+}
+```
+
+在某个组件的触发事件中设置应用迁移能力。如下例中，使用 **Button** 组件的 **onClick** 事件，触发迁移能力的改变。
+
+```ts
+// PageName.ets
+import AbilityConstant from '@ohos.app.ability.AbilityConstant';
+import common from '@ohos.app.ability.common'
+@Entry
+@Component
+struct PageName {
+  private context = getContext(this) as common.UIAbilityContext;
+  build() {
+    // ...
+    Button() {
+      //...
+    }.onClick(()=>{
+    //点击该按钮时，将应用设置为可迁移状态
+      this.context.setMissionContinueState(AbilityConstant.ContinueState.ACTIVE, (result) => {
+        console.info('setMissionContinueState ACTIVE result: ', JSON.stringify(result));
+      });
+    })
+  }
+}
+```
+
+**保证迁移连续性**
+
+由于迁移加载时，目标端拉起的应用可能执行过自己的迁移状态设置命令（如：冷启动时目标端在onCreate中设置了 **INACTIVE** ；热启动时对端已打开了不可迁移的页面，迁移状态为 **INACTIVE** 等情况）。为了保证迁移过后的应用依然具有可以迁移回发起端的能力，应在 onCreate和onNewWant的迁移调用判断中，将迁移状态设置为 **ACTIVE** 。
+
+```ts
+// EntryAbility.ets
+import UIAbility from '@ohos.app.ability.UIAbility';
+import AbilityConstant from '@ohos.app.ability.AbilityConstant';
+import Want from '@ohos.app.ability.Want';
+export default class EntryAbility extends UIAbility {
+  // ...
+  onCreate(want: Want, launchParam: AbilityConstant.LaunchParam): void {
+    // ...
+    // 调用原因为迁移时，设置状态为可迁移，应对冷启动情况
+    this.context.setMissionContinueState(AbilityConstant.ContinueState.INACTIVE, (result) => {
       console.info(`setMissionContinueState: ${JSON.stringify(result)}`);
     });
-        ```
+  }
+  onNewWant(want: Want, launchParam: AbilityConstant.LaunchParam): void {
+    // ...
+    // 调用原因为迁移时，设置状态为可迁移，应对热启动情况
+    if (launchParam.launchReason == AbilityConstant.LaunchReason.CONTINUATION) {
+      this.context.setMissionContinueState(AbilityConstant.ContinueState.ACTIVE, (result) => {
+        console.info('setMissionContinueState ACTIVE result: ', JSON.stringify(result));
+      });
+    }
+  }
+  // ...
+}
+```
+
+
 
-7. **可选配置：** 支持应用动态选择是否进行页面栈恢复（默认进行页面栈信息恢复）。如果应用不想使用系统默认恢复的页面栈，则可以设置不进行页面栈迁移，而需要在`onWindowStageRestore`设置流转后进入的页面，参数定义见[SUPPORT_CONTINUE_PAGE_STACK_KEY](../reference/apis/js-apis-app-ability-wantConstant.md#wantconstantparams)。

+## 验证指导
+
+为方便开发者验证已开发的可迁移应用，当前OpenHarmony提供了一个全局任务中心demo作为迁移的入口。下面介绍通过安装全局任务中心来验证迁移的方式。
+
+### 1. 编译安装全局任务中心
+
+#### **配置环境**
+
+public-SDK不支持开发者使用所有的系统API，例如：全局任务中心使用的[**@ohos.distributedDeviceManager**](https://gitee.com/openharmony/docs/blob/master/zh-cn/application-dev/reference/apis/js-apis-distributedDeviceManager.md)不包括在public_SDK中。因此为了正确编译安装全局任务中心，开发者需要替换full-SDK，具体操作可参见[替换指南](https://gitee.com/openharmony/docs/blob/master/zh-cn/application-dev/faqs/full-sdk-switch-guide.md)。
+
+**说明**：本文中的截图仅为参考，具体的显示界面请以实际使用的DevEco Studio和SDK的版本为准。
+
+#### **下载MissionCenter_Demo[示例代码](https://gitee.com/openharmony/ability_dmsfwk/tree/master/services/dtbschedmgr/test/missionCenterDemo/dmsDemo/entry/src/main)**
+
+#### **编译工程文件**
+
+**新建OpenHarmony 空的工程，找到对应的文件夹替换下载文件**
+
+![hop-cross-device-migration](figures/hop-cross-device-migration2.png)

+
+①打开A，B两设备的计算器
+
+②点击右上角箭头选择B设备
+
+③在B设备选择信任设备，弹出PIN码
+
+④在A设备输入PIN码
+
+⑤已组网成功，验证方法：在A设备输入数字，B设备同步出现则证明组网成功
+
+### 3.发起迁移
+
+1.在B设备打开多设备协同权限的应用，A设备打开全局任务中心demo，A设备出现A设备名称(即：本机:OpenHarmony 3.2)和B设备名称(OpenHarmony 3.2)。
+

+
+2.点击B设备名称，然后出现B设备的应用。

+
+3.最后将应用拖拽到A设备名称处，A设备应用被拉起，B设备应用退出。

    2. 获取Caller通信接口。
        Ability的context属性实现了startAbilityByCall方法，用于获取指定通用组件的Caller通信接口。如下示例通过this.context获取Ability实例的context属性，使用startAbilityByCall拉起Callee被调用端并获取Caller通信接口，注册Caller的onRelease和onRemoteStateChange监听。应用开发者根据实际业务需要做相应处理。

    1. 向被调用端发送Parcelable数据有两种方式，一种是不带返回值，一种是获取被调用端返回的数据，method以及序列化数据需要与被调用端协商一致。如下示例调用Call接口，向Callee被调用端发送数据。
       
        ```ts
+       import UIAbility, { Caller } from '@ohos.app.ability.UIAbility';
+       import { BusinessError } from '@ohos.base';

             }
         }
+        // ...
+       }
        ```
    2. 如下示例调用CallWithResult接口，向Callee被调用端发送待处理的数据originMsg，并将’CallSendMsg’方法处理完毕的数据赋值给backMsg。
       
         ```ts

 6. 释放Caller通信接口。
    Caller不再使用后，应用开发者可以通过release接口释放Caller。
 
    ```ts
+   import UIAbility, { Caller } from '@ohos.app.ability.UIAbility';
+   export default class EntryAbility extends UIAbility {
+    caller: Caller | undefined;
     releaseCall() {
         try {

                 this.caller.release();
-           this.caller = undefined
+                this.caller = undefined;
+            }
             console.info('caller release succeed');
         } catch (error) {
             console.info(`caller release failed with ${error}`);
