Image downloaded from DownloadManager queuing on Android - android

I have this code that downloads an image but for some reason the image is in my downloads as "queued" instead of downloading.
String url = file.public_url;
getContext();
DownloadManager manager = (DownloadManager) getContext().getSystemService(Context.DOWNLOAD_SERVICE);
Uri uri = Uri.parse(url);
DownloadManager.Request request = new DownloadManager.Request(uri);
request.setTitle(file.filename);
request.setDescription(file.filename + " description.");
request.allowScanningByMediaScanner();
request.setAllowedOverRoaming(true);
request.setAllowedNetworkTypes(DownloadManager.Request.NETWORK_WIFI | DownloadManager.Request.NETWORK_MOBILE);
request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, file.filename + file.file_extension);
manager.enqueue(request);


I have successfully downloaded the images with this Async version that doesn't use DownloadManager https://stackoverflow.com/a/3028660/6136947

I have used DownloadManager class for image download. When I have used below image url in browser it is working fine. but when i have downloaded that image url using DownloadManager it is getting .zip format.
Image Url : Here
Below is my code of download Manager :
private void startDownload(String url) {
DownloadManager downloadManager = (DownloadManager) getSystemService(DOWNLOAD_SERVICE);
Uri Download_Uri = Uri.parse(url);
DownloadManager.Request request = new DownloadManager.Request(Download_Uri);
request.setAllowedNetworkTypes(DownloadManager.Request.NETWORK_WIFI | DownloadManager.Request.NETWORK_MOBILE);
request.setAllowedOverRoaming(true);
MimeTypeMap mimeTypeMap = MimeTypeMap.getSingleton();
String mimeString = mimeTypeMap.getMimeTypeFromExtension(MimeTypeMap.getFileExtensionFromUrl(url));
request.setMimeType(mimeString);
request.setTitle(getString(R.string.app_name));
request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
//Set a description of this download, to be displayed in notifications (if enabled)
request.setDescription("Downloading " + txtDocName.getText().toString());
//Set the local destination for the downloaded file to a path within the application's external files directory
request.setDestinationInExternalFilesDir(this, Environment.DIRECTORY_DOWNLOADS, System.currentTimeMillis() + ".jpeg");
downloadManager.enqueue(request);
AppLog.showD(TAG, "downloadind started");
}

The provided URL returns zip as a type. You can check that using any dev tool on your browser as demonstrated in this screen shot

How to detect the extension of file to download using DownloadManager in Android?

I start developing my very first Android project. In my project, I need to download media files, especially mp3 or mp4. I am downloading file using DownloadManager.
Here is my download code for mp3
private void downloadPodcast(int id)
{
String url = context.getResources().getString(R.string.api_endpoint)+"podcast/download?id="+String.valueOf(id);
DownloadManager.Request request = new DownloadManager.Request(Uri.parse(url));
request.setDescription("Downloading...");
request.setTitle("Podcast");
request.setMimeType("audio/MP3");
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
request.allowScanningByMediaScanner();
request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
}
request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, "audio.mp3");
DownloadManager manager = (DownloadManager) context.getSystemService(Context.DOWNLOAD_SERVICE);
manager.enqueue(request);
}
As you can see in my code, I am downloading only mp3 and setting the MIME type is constant. The file name and its extension is constant as well. What I want to do is to detect the file extension I will download. So can I set the MIME type programmatically and set the extension of file name. How can I achieve it in DownloadManager?

Though its quite late, however here is the answer:
You can get the extension of the file to download using the code below and add the extension to your file name.
String fileUrl = "http://someurl";
String fileName = "foobar";
String fileExtension = MimeTypeMap.getFileExtensionFromUrl(fileUrl);
// concatinate above fileExtension to fileName
fileName += "." + fileExtension;
DownloadManager.Request request = new DownloadManager.Request(Uri.parse(fileUrl))
.setTitle(context.getString(R.string.app_name))
.setDescription("Downloading " + fileName)
.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE | DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED)
.setAllowedNetworkTypes(DownloadManager.Request.NETWORK_WIFI | DownloadManager.Request.NETWORK_MOBILE)
.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, fileName);
DownloadManager dm = (DownloadManager) context.getSystemService(Context.DOWNLOAD_SERVICE);
dm.enqueue(request);
