如何将下载的文件保存到android的内部存储中？ [英] how to save a downloaded file into internal storage in android?

问题描述

我已经使用下面的代码从android studio服务器中下载了视频，并且可以正常工作，但是当我在设备中搜索视频时，在任何地方都找不到它...它在哪里保存以及如何更改目的地

i have used the below code to download a video from server in android studio and it works correctly , but when i search the video in my device i cant find it anywhere ... where does it save and how can i change destination directory on "internal storage"?

private DownloadManager downloadManager;

btn_download_video.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            downloadManager = (DownloadManager) getSystemService(Context.DOWNLOAD_SERVICE);
            Uri uri = Uri.parse(urlVideo);
            DownloadManager.Request request = new DownloadManager.Request(uri);
            request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
            request.setDestinationInExternalFilesDir(Video_detail_Activity.this, Environment.DIRECTORY_DOWNLOADS, videoName);
            Long reference = downloadManager.enqueue(request);

        }
 });

我在项目中也使用了以下权限：

i used below permissions in my project too:

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

推荐答案

感谢您的帮助... ... pskink 说我更改了

thanks for helping ... as pskink said i changed

request.setDestinationInExternalFilesDir(Video_detail_Activity.this, Environment.DIRECTORY_DOWNLOADS, videoName);

至

request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS.toString(), videoName+".mp4");

现在我可以在下载文件夹中看到下载的文件。

and now i can see downloaded file in "Download" folder.
