DownloadManager.Request


public static class DownloadManager.Request
extends Object

java.lang.Object
   ↳ android.app.DownloadManager.Request


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(android.net.Uri).

By default, downloads are saved to a generated filename in the shared download cache and may be deleted by the system at any time to reclaim space.

For applications targeting Build.VERSION_CODES.Q or above, WRITE EXTERNAL_STORAGE permission is not needed and the uri must refer to a path within the directories owned by the application (e.g. Context#getExternalFilesDir(String)) or a path within the top-level Downloads directory (as returned by Environment#getExternalStoragePublicDirectory(String) with Environment#DIRECTORY_DOWNLOADS).
