i m使用以下代码,但不知道文件在哪里下载。没有存储在给定路径的文件。代码需要什么更正。代码在开始时创建文件夹。
String path = Environment.getExternalStorageDirectory().getPath() + "/Myapp/Videos";
System.out.println(path);
File folder = new File(path);
if (folder.canExecute()) {
System.out.println("Video Folder Found");
} else {
folder.mkdirs();
}
DownloadManager.Request request = new DownloadManager.Request(uri);
request.setDescription("Selected Video is being downloaded");
request.allowScanningByMediaScanner();
request.setTitle("Downloading Video");
request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
request.setDestinationInExternalFilesDir(mContext, null, title + ".mp4");
DownloadManager manager = (DownloadManager) mContext.getSystemService(Context.DOWNLOAD_SERVICE);
manager.enqueue(request);
return null;
只需使用
request.setDestinationInExternalPublicDir("/Path", "test.mp4");
这就是我解决问题的方式
request.setDestinationinexternalFilesdir(上下文,"/path/"," myfile.txt");
