title: Resume download from Download Manager android when download is failed
body: <p>I am using DownloadManager service to download files. I want it to resume the download if it is failed by any case(for example internet got disconnected). I am saving the download id generated when we enqueue the request for download. Can I resume download using that id? Or with any other method?</p>
