I am using DownloadManager service to download files. 我正在使用DownloadManager服务来下载文件。 I want it to resume the download if it is failed by any case(for example internet got disconnected). 我希望它在任何情况下都失败（例如，Internet断开连接）时恢复下载。 I am saving the download id generated when we enqueue the request for download. 当我们将下载请求加入队列时，我将保存生成的下载ID。 Can I resume download using that id? 我可以使用该ID恢复下载吗？ Or with any other method? 或其他方法？

It's good habit to check documentation first. 首先检查文档是个好习惯。 DownloadManager documentation says: DownloadManager 文档说：

The download manager will conduct the download in the background, taking care of HTTP interactions and retrying downloads after failures or across connectivity changes and system reboots. 下载管理器将在后台进行下载，处理HTTP交互，并在出现故障或在连接更改和系统重新启动后重试下载。

Thanks to @Marcin's suggestion, I checked the documentation for DownloadManager. 感谢@Marcin的建议，我检查了DownloadManager的文档。 The problem with the link I posted was that it was not having resume capability. 我发布的链接的问题在于它没有恢复功能。 That's why after it failed due to internet disconnection, it won't resume. 这就是为什么在由于Internet断开而失败后，它将无法恢复的原因。 I tried other links with resume capability, and they all resume perfectly after internet re-connection. 我尝试了其他具有恢复功能的链接，并且它们在重新连接互联网后都能完美恢复。
