DownloadManager not storing Downloaded files in Download Folder
提问by architjn
Whenever i try to download any file through the code below
每当我尝试通过下面的代码下载任何文件时
dm = (DownloadManager) context.getSystemService(context.DOWNLOAD_SERVICE);
request = new Request(
Uri.parse(finalurl));
enqueue = dm.enqueue(request);
BroadcastReceiver receiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if (DownloadManager.ACTION_DOWNLOAD_COMPLETE.equals(action)) {
long downloadId = intent.getLongExtra(
DownloadManager.EXTRA_DOWNLOAD_ID, 0);
Query query = new Query();
query.setFilterById(enqueue);
Cursor c = dm.query(query);
if (c.moveToFirst()) {
int columnIndex = c
.getColumnIndex(DownloadManager.COLUMN_STATUS);
if (DownloadManager.STATUS_SUCCESSFUL == c
.getInt(columnIndex)) {
Toast.makeText(context, "download finished", Toast.LENGTH_LONG).show();
}
}
}
}
};
context.registerReceiver(receiver, new IntentFilter(
DownloadManager.ACTION_DOWNLOAD_COMPLETE));
The file downloaded shows in Download Manager Application and can be played from there any time but that is not storing the downloaded file in Downloads folder.
下载的文件显示在下载管理器应用程序中，可以随时从那里播放，但不会将下载的文件存储在下载文件夹中。
If i use
如果我使用
.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, "filename.extention"));
i get the same result.
我得到相同的结果。
My question is- Where are my downloads going and how can i bring them to downloads folder?
我的问题是 - 我的下载去哪里了，我怎样才能把它们带到下载文件夹？

To see the downloaded files, you must have File Manager app installed in your phone. Steps to view downloaded files:
要查看下载的文件，您必须在手机中安装文件管理器应用程序。查看下载文件的步骤：
- Open File Manager app.
- Go to storage -> sdcard
- Go to Android -> data -> "Your package name" eg. com.xyx.abc
- Here are all your downloads.
- 打开文件管理器应用程序。
- 转到存储 - > SD卡
- 转到 Android -> 数据 -> “您的包名称”，例如。com.xyx.abc
- 这是你所有的下载。
Path is: storage/sdcard/Android/data/"your package"
路径为：storage/sdcard/Android/data/“你的包”
Use below methos to save files in Download folder

这会将文件保存到
Environment.getExternalStorageDirectory() + "/folder"

If you try to find where the DownloadManager stored the file using
如果您尝试使用以下方法查找 DownloadManager 存储文件的位置
String file = <Cursor>.getColumnIndex(DownloadManager.COLUMN_LOCAL_URI)
you get a ficticious path: "context://downloads/my_downloads/{number}". To see the actual path, use:
你会得到一个虚构的路径：“context://downloads/my_downloads/{number}”。要查看实际路径，请使用：
String file = <Cursor>.getColumnIndex(DownloadManager.COLUMN_LOCAL_FILENAME)
You then get: "/data/user/0/com.android.providers.downloads/cache/{filename}" (or something similar) and you can access the file from there.
然后你会得到：“/data/user/0/com.android.providers.downloads/cache/{filename}”（或类似的东西），你可以从那里访问文件。
