How to get the downloaded file path using the download manager

I am able to download a video from the server using the download manager. However when I log the path using below code.

 String path = Environment.getExternalStoragePublicDirectory(directory).getAbsolutePath() + subpath;
 Log.e("PATH", path);

I get

12-15 13:29:36.787 22807-22807/com.ezyagric.extension.android E/PATH: /storage/sdcard0/EZYAGRIC/Soil Testing.mp4.

Now this is different from the path on the phone which is

/storage/sdcard0/Android/data/com.ezyagric.extension.android/files/EZYAGRIC/Crop Insurance.mp4

What brings that difference and how can obtain the path in the phone the way it is?

To download file without callback you can just enqueue it.

val fileUrl = "https://example.com/myfile.pdf"
val fileName = "myfile.pdf"
val fileExtension = File(fileName).extension
 val request = DownloadManager.Request(fileUrl.toUri()).apply {
            setDestinationInExternalPublicDir(
                Environment.DIRECTORY_DOWNLOADS,
                fileName
            )
            setMimeType(
                MimeTypeMap.getSingleton()
                    .getMimeTypeFromExtension(fileExtension)
            )
            allowScanningByMediaScanner()
            setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_ONLY_COMPLETION)
            setAllowedNetworkTypes(DownloadManager.Request.NETWORK_WIFI or DownloadManager.Request.NETWORK_MOBILE)
        }

        val idDownloded = downloadManager?.enqueue(request) ?: return

But if you make the same downloads many times, then downloaded files will be stored as : "myfile-1.pdf", "myfile-2.pdf", "myfile-3.pdf"...

So, to get downloaded file path you need to do this:

val fileDownloadedUri = downloadManager.getUriForDownloadedFile(idDownloded)//content://downloads/all_downloads/43
val mimeType = downloadManager.getMimeTypeForDownloadedFile(idDownloded)

val fileDownloadedPath = FilesUtils.getPath(
            context = activity,
            uri = fileDownloadedUri
        )

where FilesUtils (https://github.com/coltoscosmin/FileUtils/blob/master/FileUtils.java) from here (https://stackoverflow.com/a/53021624/2425851)

Then you may share the downloaded file:

val file = File(fileDownloadedPath)
        if (!file.exists()) {
            //error
            return
        }

        val uriForFile = FileProvider.getUriForFile(
            activity,
            BuildConfig.APPLICATION_ID,
            file
        )

        val intent = Intent().apply {
            action = Intent.ACTION_SEND
            type = mimeType
            putExtra(Intent.EXTRA_STREAM, uriForFile)
            addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION)
        }

        activity.startActivity(
            Intent.createChooser(
                intent,
                "Share"
            )
        )

When you call --> downloadManager.enqueue(request) method before set their path 

request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS,"Google.gif");

File file = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS),"google.gif"); // Set Your File Name
if (file.exists()) {
    Bitmap myBitmap = BitmapFactory.decodeFile(file.getAbsolutePath());
    pro28_imageView.setImageBitmap(myBitmap);
}

Code snippet to download file in default download directory.

DownloadManager.Request dmr = new DownloadManager.Request(Uri.parse(url));

// If you know file name
String fileName = "filename.xyz"; 

//Alternative if you don't know filename
String fileName = URLUtil.guessFileName(url, null,MimeTypeMap.getFileExtensionFromUrl(url));

dmr.setTitle(fileName);
dmr.setDescription("Some descrition about file"); //optional
dmr.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, fileName);
dmr.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
dmr.setAllowedNetworkTypes(DownloadManager.Request.NETWORK_WIFI | DownloadManager.Request.NETWORK_MOBILE);
DownloadManager manager = (DownloadManager) mContext.getSystemService(Context.DOWNLOAD_SERVICE);
manager.enqueue(dmr);

Note For mContext.getSystemService

  • Activity= getSystemService();
  • Fragment= getActivity.getSystemService();
  • Adapter= mContext.getSystemService(); //pass context in adapter

UPDATE

As OP want to check file exist or not

File file = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS), fileName); 
if(file.exists()){//File Exists};

You should try to download in download folder

        String url = "url you want to download";
        DownloadManager.Request request = new 
        DownloadManager.Request(Uri.parse(url));
        request.setDescription("Some descrition");
        request.setTitle("Some title");
        request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, "name-of-the-file.ext");

        // get download service and enqueue file
        DownloadManager manager = (DownloadManager) getSystemService(Context.DOWNLOAD_SERVICE);
        manager.enqueue(request);
