I want to download some audio files from the internet. I want to use downloadmanager to download this file but I don't know how to save these files to a specific internal storage location in android. InternalStorage/folder/filename.mp3 (so I can access them easily).

manager = (DownloadManager) getSystemService(Context.DOWNLOAD_SERVICE);
                Uri uri = Uri.parse("URL");
                DownloadManager.Request request = new DownloadManager.Request(uri);
                request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE);
                long reference = manager.enqueue(request);

It is useful for downloading. But we cannot specify the location for these files.

So how to specify these files to be saved in the internal storage at a specific location. And also, how to access and delete these files.

Please don't devote this question as I got confused while going through many articles.

if any other better alternative or any suggestion comment down

Check the request.setDestination functions here To Store file in External App-Specific Directory [example: "external/Android/data/your_app_name/filePath_you_set_in_function”], use like below:

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);
//Set the local destination for the downloaded file to a path within the application's external files directory
request.setDestinationInExternalFilesDir(context, Environment.DIRECTORY_DOWNLOADS, fileName); //To Store file in External Public Directory use "setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, fileName)"
DownloadManager manager = (DownloadManager)
mContext.getSystemService(Context.DOWNLOAD_SERVICE);
manager.enqueue(request);

And if you want to download it to another place you need to move it after your download gets finished, by using IO streams. You can use a broadcast receiver to perform this task once the DownloadManager has finished downloading. You can use FileProvider to open the file with another app in Android version 10 or above.

  • "Path" is not a public dir so that will not go. And they are no callbacks. – blackapps Jun 10 '21 at 12:06

    Sorry, but your update makes it even worse by supplying a full parh. And the legacy permission request is not needed. Never. – blackapps Jun 10 '21 at 12:42

    @blackapps, This working well at my end. Please share the other option if you have one. – Akki Jun 10 '21 at 18:24
  • @Akki but how to retrieve and delete that specific file. (I am using `request.setDestinationInExternalFilesDir`) – Sachin Burdak Jun 11 '21 at 09:14
  • @SachinBurdak, You have already answered!. yes, to get the specific file use "context.getExternalFilesDir(Environment.DIRECTORY_DOWNLOADS), fileName)" – Akki Jun 11 '21 at 18:02

simply add this line to save file:

request.setDestinationInExternalFilesDir(context,Environment.DIRECTORY_ALARM,mp3name);

to delete this file

File file = new 
File(context.getExternalFilesDir(Environment.DIRECTORY_ALARMS),"Fav_Ringtone.mp3");

file.delete();

to read this file

File file= newFile(context.getExternalFilesDir(Environment.DIRECTORY_ALARMS),"Fav_Ringtone.mp3");
