# WorkSchedulerExtensionAbility(延迟任务调度回调
# 延迟任务调度回调开发指导(WorkSchedulerExtensionAbility
## 延迟任务概述
对于实时性要求不高的任务或持久性任务,可以使用延迟调度任务,该机制在满足应用设定条件的时候,会根据系统当前状态,如内存、功耗、温度等统一决策调度时间。
对于实时性要求不高的任务或持久性任务,可以使用延迟调度任务,该机制会在应用满足应用设定条件(包括网络类型、充电类型、存储状态、电池状态、定时状态)时,根据系统当前状态,由系统统一决策调度时间。
WorkSchedulerExtensionAbility提供了延迟任务回调能力,在延迟任务开始和结束时,系统会通过接口回调应用,开发者可在回调接口里面处理自己的任务逻辑。

### 开发延迟任务调度接口
1. 在library对应的ets目录(./library/src/main/ets)下,新建ts文件并命名为DelayWork.ts,用于实现延迟任务API。

```ts
import workScheduler from '@ohos.resourceschedule.workScheduler'

```ts
export default class DelayWork {
private workInfo = {
workId: 1,
networkType: workScheduler.NetworkType.NETWORK_TYPE_WIFI,
bundleName: '',
abilityName: ''
}
// 注册延迟调度任务
startWork(bundleName: string, abilityName: string) {
this.workInfo.bundleName = bundleName
this.workInfo.abilityName = abilityName
try {
workScheduler.startWork(this.workInfo)
Logger.info(TAG, `startWork success`)
} catch (error) {
Logger.error(TAG, `startWork startwork failed. code is ${error.code} message is ${error.message}`)
prompt.showToast({
message: `${error.message}`
})
}
}
```ts
export default class DelayWork {
private workInfo = {
workId: 1,
networkType: workScheduler.NetworkType.NETWORK_TYPE_WIFI,
bundleName: '',
abilityName: ''
}
// 注册延迟调度任务
startWork(bundleName: string, abilityName: string) {
this.workInfo.bundleName = bundleName
this.workInfo.abilityName = abilityName
try {
workScheduler.startWork(this.workInfo)
Logger.info(TAG, `startWork success`)
} catch (error) {
Logger.error(TAG, `startWork startwork failed. code is ${error.code} message is ${error.message}`)
prompt.showToast({
message: `${error.message}`
})
}
}
// 停止延迟调度任务
stopWork(bundleName: string, abilityName: string) {
this.workInfo.bundleName = bundleName
this.workInfo.abilityName = abilityName
workScheduler.stopWork(this.workInfo, false)
Logger.info(TAG, `stopWork`)
}
}
```
// 停止延迟调度任务
stopWork(bundleName: string, abilityName: string) {
this.workInfo.bundleName = bundleName
this.workInfo.abilityName = abilityName
workScheduler.stopWork(this.workInfo, false)
Logger.info(TAG, `stopWork`)
}
}
```
3. 在工程entry Module对应的index页面(./entry/src/main/ets/pages/index.ets)下,增加“升级”按钮,调用library封装的延迟任务注册接口。

```ts
aboutToDisappear() {
this.work.stopWork('ohos.samples.workscheduler', 'WorkTest')
}
```
```ts
aboutToDisappear() {
this.work.stopWork('ohos.samples.workscheduler', 'WorkTest')
}
```
### 配置文件
1. 在工程entry Module对应的[module.json5配置文件](../quick-start/module-configuration-file.md)中注册WorkSchedulerExtensionAbility,type标签需要设置为“workScheduler”,srcEntrance标签表示当前ExtensionAbility组件所对应的代码路径。
```json
{
"module": {
```json
{
"module": {
"extensionAbilities": [
{
"name": "WorkTest",
......@@ -193,9 +191,9 @@ import { workAbility } from '@ohos/library'
"type": "workScheduler"
}
]
}
}
```
}
}
```
