String url = "https://www.dropbox.com/s/zf68ylazusvpnga/Cir_IMG-10-
20181025145334.jpg?raw=1";
DownloadManager.Request request = new
DownloadManager.Request(Uri.parse(url.trim()));
request.setAllowedNetworkTypes(DownloadManager.Request.NETWORK_WIFI
| DownloadManager.Request.NETWORK_MOBILE).setAllowedOverRoaming(false);
request.setDestinationInExternalFilesDir(this, "/images", "sample");
final DownloadManager manager =
(DownloadManager)getSystemService(Context.DOWNLOAD_SERVICE);
final long downloadId = manager.enqueue(request);
Log.d(SO, " download id " + downloadId);`为我工作。
