应用appName 该如何获取到值, 而不是资源引用值 $string:app_name

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’))) 
console.info("testTag, app name is " + this.context.resourceManager.getStringSync(data.appInfo.labelId)) 
})
