使用保管箱下载文件 url android

Question

我正在尝试使用保管箱 url 下载文件。我从 Download a file with Android, and showing the progress in a ProgressDialog 复制了一个使用 DownloadManager class.

的代码

    public void downloadFromDropBoxUrl(View view) {
        //verfying if the downloadmanager is available first.
        if (isDownloadManagerAvailable(getApplication())) {
            String url = "https://www.dropbox.com/s/m4z5u9qstxdtbc3/AllExams22.pdf?dl=0";
            DownloadManager.Request request = new DownloadManager.Request(Uri.parse(url));
            request.setDescription("Some descrition");
            request.setTitle("Some title");
// in order for this if to run, you must use the android 3.2 to compile your app
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
                request.allowScanningByMediaScanner();
                request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
            }
            request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, "my-map.pdf");

// get download service and enqueue file
            DownloadManager manager = (DownloadManager) getSystemService(Context.DOWNLOAD_SERVICE);
            manager.enqueue(request);
        }
    }
    public static boolean isDownloadManagerAvailable(Context context) {

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.GINGERBREAD) {
            return true;
        }
        return false;
    }

它正在使用 urls 获取直接文件，但这次我尝试使用 Dropbox 共享链接来实现，但没有成功。我不想连接到保管箱 api。我觉得没用。有什么方法可以直接从保管箱下载文件吗url?

Answer 2

只是替换

String url = "https://www.dropbox.com/s/m4z5u9qstxdtbc3/AllExams22.pdf?dl=0";

作者：

String url = "https://dl.dropboxusercontent.com/s/m4z5u9qstxdtbc3/AllExams22.pdf";

然后：

final DownloadTask downloadTask = new DownloadTask(YourActivity.this);
downloadTask.execute(url);
