HarmonyOS 防录屏

目前了解到系统并没有防录屏功能，如果想针对某页面进行防录屏截屏操作，防止截屏示例demo如下：

在module.json5中添加权限

"requestPermissions": [ { "name": "ohos.permission.PRIVACY_WINDOW" } ] 

//XXX.ets 
import { window } from '@kit.ArkUI';

@Entry
@Component
struct Index {
  @State message: string = 'Hello World';
  @State isPrivacyMode: boolean = true;

  async aboutToAppear() {
    let ww = await window.getLastWindow(getContext(this))
    await ww.setWindowPrivacyMode(true);
  }

  build() {
    RelativeContainer() {
      Text(this.message)
    }.height('100%').width('100%')
  }
}
