title: Error in download manager android
body: <p>Using Android Download Manager i am trying to implement multiple download of pdf files synchronously (ie,an instance of the request is generated after successful completion of the previous request),soon after a DOWNLOAD_SUCCESS notification in the broadcast receiver,a duplicate copy of the same request(with the same request id ) is generated and the DownlaodManager is initiated implicitly.For the second time the download fails,and DownlaodManager gives DownloadManager.status = ERROR CANNOT RESUME.Hence,pdf is not downloaded.This happens only when i try synchronized multiple download.
  Any help is appreciated.</p>
