   ↳ android.app.DownloadManager.Request

Class Overview

This class contains all the information necessary to request a new download. The URI is the only required parameter. Note that the default download destination is a shared volume where the system might delete your file if it needs to reclaim space for system use. If this is a problem, use a location on external storage (see setDestinationUri(Uri).
