HarmonyOS 如何通过代码获取应用名称

获取应用名称demo如下：

import { bundleManager, common } from '@kit.AbilityKit';

@Entry
@Component
struct Page4 {
  @State message: string = 'Hello World';

  build() {
    Row() {
      Column() {
        Text(this.message)
          .fontSize(50)
          .fontWeight(FontWeight.Bold)
          .onClick(() => {
            this.appName();
          })
      }
      .width('100%')
    }
    .height('100%')
  }

  appName(): Promise<string> {
    return new Promise((resolve, reject) => {
      bundleManager.getBundleInfoForSelf(bundleManager.BundleFlag.GET_BUNDLE_INFO_WITH_APPLICATION)
        .then((data: bundleManager.BundleInfo) => {
          console.info("testTag, app name is " + this.context.resourceManager.getStringSync($r('app.string.app_name').id));
          console.info("testTag, app name is " + this.context.resourceManager.getStringSync($r('app.string.app_name')))
          console.info("testTag, app name is " + this.context.resourceManager.getStringSync(data.appInfo.labelId))
          console.info("testTag, app name is " + JSON.stringify(data.appInfo.label))

        })
    })
  }
}

label就是获取 标识应用的名称，使用示例：“label”: “$string: mainability_description”。 规格如此通过获取labelId能实现获取应用名称

this.context.resourceManager.getStringSync(data.appInfo.labelId))
