 3. 在DataShareExtAbility.ts文件中，导入
 `@ohos.application.DataShareExtensionAbility`模块，开发者可根据应用需求选择性重写其业务实现。例如数据提供方只提供插入、删除和查询服务，则可只重写这些接口，并导入对应的基础依赖模块。
    
-```ts

-import rdb from '@ohos.data.relationalStore';
-import dataSharePredicates from '@ohos.data.dataSharePredicates';

 1. 导入基础依赖包。
    
-```ts
-import UIAbility from '@ohos.app.ability.UIAbility';
-import dataShare from '@ohos.data.dataShare';
-import dataSharePredicates from '@ohos.data.dataSharePredicates';

+   import { ValuesBucket } from '@ohos.data.ValuesBucket'
+   import window from '@ohos.window';
+   ```
 
 2. 定义与数据提供方通信的URI字符串。
    
-```ts
-// 作为参数传递的URI，与module.json5中定义的URI的区别是多了一个"/"，是因为作为参数传递的URI中，在第二个与第三个"/"中间，存在一个DeviceID的参数

 3. 创建工具接口类对象。
    
-```ts
-let dsHelper: dataShare.DataShareHelper | undefined = undefined;
-let abilityContext: Context;
-
-export default class EntryAbility extends UIAbility {
-  onWindowStageCreate(windowStage: window.WindowStage) {
