我正在尝试使用 DownloadManager 将文件从 URL 下载到 /storage/emulated/0/Download
DownloadManager downloadManager = (DownloadManager) context.getApplicationContext().getSystemService(DOWNLOAD_SERVICE);
DownloadManager.Request request = new DownloadManager.Request(Uri.parse(url));
request.allowScanningByMediaScanner();
request.setAllowedNetworkTypes(DownloadManager.Request.NETWORK_WIFI | DownloadManager.Request.NETWORK_MOBILE);
request.setAllowedOverRoaming(false);
request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
request.setTitle("blah");
String path = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS).getAbsoluteFile().toString();
System.out.println(path);
request.setDestinationInExternalPublicDir(path, title);
request.setVisibleInDownloadsUi(true);
final long downloadReference = downloadManager.enqueue(request);
我已经确认 path 确实返回了所需的下载路径。我的问题是，当文件实际下载时，它们最终会到达 /documents/blah ，如果卸载应用程序，文件将从设备中删除。
最佳答案
你试过吗
request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, file.name());
