使用android下载管理器下载多个文件

I want to download say 5 zip files from url so right now I am calling the DownloadManger 5 times.Is this approach ok or I should call the logic of downloading the files inside for loop by just calling the DownloadManger class once. And also is this possible to download multiple files using Download manager and broadcast after last file completed the downloading.Please suggest some idea.I want to download say 5 zip files from url so
