HarmonyOS 鸿蒙Next App版本升级后应用更新时间

获取应用包更新时间updateTime推荐使用getBundleInfoForSelf获取，参考：

https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V5/js-apis-bundlemanager-V5#bundlemanagergetbundleinfoforself

获取demo如下：

hljs import bundleManager from ‘@ohos.bundle.bundleManager’; import { BusinessError } from ‘@ohos.base’; import hilog from ‘@ohos.hilog’;

@Entry @Component struct Index { @State message: string = ‘getUpdateTime’;

build() { Row() { Column() { Text(this.message).fontSize(50).fontWeight(FontWeight.Bold).onClick(() => { let bundleFlags = bundleManager.BundleFlag.GET_BUNDLE_INFO_DEFAULT; try { bundleManager.getBundleInfoForSelf(bundleFlags).then((data) => { hilog.info(0x0000, ‘testTag’, ‘getBundleInfoForSelf successfully. Data: %{public}s’, JSON.stringify(data.updateTime)); }).catch((err: BusinessError) => { hilog.error(0x0000, ‘testTag’, ‘getBundleInfoForSelf failed. Cause: %{public}s’, err.message); }); } catch (err) { let message = (err as BusinessError).message; hilog.error(0x0000, ‘testTag’, ‘getBundleInfoForSelf failed: %{public}s’, message); } }) }.width(‘100%’) }.height(‘100%’) } }
