HarmonyOS appRecovery.restartApp()方法无效

请参考以下步骤：

1、创建Ability，目录：ets/abilityStage/MyAbilityStage.ets

import appRecovery from '@ohos.app.ability.appRecovery';
import AbilityStage from '@ohos.app.ability.AbilityStage';
import { Want } from '@kit.AbilityKit';

export default class MyAbilityStage extends AbilityStage {
  onCreate() {
    appRecovery.enableAppRecovery(appRecovery.RestartFlag.ALWAYS_RESTART, appRecovery.SaveOccasionFlag.SAVE_WHEN_ERROR,
      appRecovery.SaveModeFlag.SAVE_WITH_FILE);
    let want: Want = {
      bundleName: 'com.example.restartapptest', abilityName: "EntryAbility"
    }
    appRecovery.setRestartWant(want)
  }
}

2、配置Ability作为启动ability。在module.json5文件中的module子级中配置srcEntry，如：

"module": {
"name": "entry",
"srcEntry": "./ets/abilityStage/MyAbilityStage.ets",
"type": "entry",
...
}

3、设置需要重启的UIAiblity。在module.json5文件中，如下：

"abilities": [
  {
"name": "EntryAbility",
"srcEntry": "./ets/entryability/EntryAbility.ets",
"recoverable": true,
...
  }
]

4、在页面执行重启APP的操作。

Button('restartApp')
  .onClick(() => {
    console.log('restartApp clicked')
    appRecovery.restartApp();
  })

appRecovery.restartApp()两次重启的间隔应大于一分钟，一分钟之内重复调用此接口只会退出应用不会重启应用，参考文档：https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V5/js-apis-app-ability-apprecovery-V5#apprecoveryrestartapp
