I am downloading files from server using DownloadManager class
Here is what i am doing
public void downloadPdf(String url, String sem, String title, String branch) {
Uri Download_Uri = Uri.parse(url);
DownloadManager.Request request = new DownloadManager.Request(Download_Uri);
//Restrict the types of networks over which this download may proceed.
request.setAllowedNetworkTypes(DownloadManager.Request.NETWORK_WIFI | DownloadManager.Request.NETWORK_MOBILE);
//Set whether this download may proceed over a roaming connection.
request.setAllowedOverRoaming(false);
//Set the title of this download, to be displayed in notifications (if enabled).
request.setTitle("Downloading");
//Set a description of this download, to be displayed in notifications (if enabled)
request.setDescription("Downloading File");
//Set the local destination for the downloaded file to a path within the application's external files directory
request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, title + "_" + branch + "_" + sem + "Year" + System.currentTimeMillis() + ".pdf");
//Enqueue a new download and same the referenceId
downloadReference = downloadManager.enqueue(request);
}
thing is when download is complete if then user clicks on notification it should open that file what should i do in this code
BroadcastReceiver onNotificationClick = new BroadcastReceiver() {
public void onReceive(Context ctxt, Intent intent) {
}
};

Finally fixed this by just 2 lines
request.allowScanningByMediaScanner();

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

Show On Going Download progress in a RecyclerView in Android

I am currently working on app where you can download video files. I am using Download manager for downloading files and everything is working fine as the files are being downloaded properly and I can see the progress of downloading in my notifications. Now I want to show those downloading files in another class (containing recyclerview) with the progress. So what should i do to implement this module?
Currently my downloading file code is:
public static long fileDownloader(Activity context, Video video) {
File direct = new File(Environment.getExternalStorageDirectory()
+ "/FWV Videos");
if (!direct.exists()) {
direct.mkdirs();
}
DownloadManager mgr = (DownloadManager) context.getSystemService(Context.DOWNLOAD_SERVICE);
Uri downloadUri = Uri.parse(video.getVideoURL());
DownloadManager.Request request = new DownloadManager.Request(
downloadUri);
request.setAllowedNetworkTypes(
DownloadManager.Request.NETWORK_WIFI
| DownloadManager.Request.NETWORK_MOBILE)
.setAllowedOverRoaming(false).setTitle(video.getName())
.setDescription("Downloading file...")
.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED)
.setVisibleInDownloadsUi(false)
.setDestinationInExternalPublicDir("/FWV Videos", video.getName() + ".mp4")
.allowScanningByMediaScanner();
Toast.makeText(context, "Download started", Toast.LENGTH_SHORT).show();
return mgr.enqueue(request);
}
I just want a separate list where i can show on going downloads and completed downloads

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);

How I can download video in my application like we download or install apk file on google play?

I want to download video from URL in background like we install apk file in background from Google play. I want to show downloading indicator on notification bar same like it showing while we download or install apk file. if any suggestion or idea then suggest me how I can achieve this task in my project.
You can prefer android DownLoadManager. somehow want to do like this in your activity
String mUrl="your video url";
DownloadManager manager = (DownloadManager) getSystemService(DOWNLOAD_SERVICE);
Request request = new Request(Uri.parse(mUrl));
request.setDestinationInExternalFilesDir(getApplicationContext(), Environment.DIRECTORY_DOWNLOADS, your_fileName);
request.setNotificationVisibility(Request.VISIBILITY_VISIBLE);
request.setAllowedOverRoaming(false);
request.setAllowedNetworkTypes(DownloadManager.Request.NETWORK_WIFI | DownloadManager.Request.NETWORK_MOBILE);
manager.enqueue(request);
setNotificationVisibility() -> show download notification in notification bar(window) with download progress also.
below are three methods where you can choose destination for your downloaded file path.
1. setDestinationInExternalFilesDir(Context context, String dirType, String subPath)
Set the local destination for the downloaded file to a path within the application's external files directory (as returned by getExternalFilesDir(String).
2. setDestinationInExternalPublicDir(String dirType, String subPath)
Set the local destination for the downloaded file to a path within the public external storage directory (as returned by getExternalStoragePublicDirectory(String)).
3. setDestinationUri(Uri uri)
Set the local destination for the downloaded file.
Use Download Manager,
private void for_call_download() {
File folder = Environment.getExternalStoragePublicDirectory(DOWNLOAD_FOLDER_NAME);
if (!folder.exists() || !folder.isDirectory()) {
folder.mkdirs();
}
try {
DownloadManager.Request request = new DownloadManager.Request(Uri.parse(APK_URL));
request.setDestinationInExternalPublicDir(DOWNLOAD_FOLDER_NAME, DOWNLOAD_FILE_NAME);
request.setTitle(SessionName);
request.setDescription("" + SessionDesc);
request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
request.setVisibleInDownloadsUi(false);
request.setMimeType("application/cn.trinea.download.file");
downloadId = downloadManager.enqueue(request);
} catch (IllegalStateException i) {
showAlert(context, "Sorry Some Problem");
i.printStackTrace();
}
updateView();
status_download = true;
}

Android downloading file through DownloadManager not working correctly

I'm trying to download files thru DownloadManager, it works perfectly on most of the phones (Nexus family, S3, etc) but on Galaxy S2 for some reason the download works, but the name of the file is set wrong and when I try to open it (either from notification, either downloads app) it says that the file cannot be opened, even for files like jpeg, gif, png, etc.
Here is the code:
DownloadManager downloadManager = (DownloadManager) service
.getSystemService(Context.DOWNLOAD_SERVICE);
DownloadManager.Request downloadReq = new DownloadManager.Request(
Uri.parse(URL));
downloadReq
.setAllowedNetworkTypes(DownloadManager.Request.NETWORK_WIFI
| DownloadManager.Request.NETWORK_MOBILE);
downloadReq.allowScanningByMediaScanner();
downloadReq.setMimeType(attachment.mimeType);
downloadReq.setTitle(attachment.fileName);
downloadReq.setDescription("attachment");
downloadReq.setDestinationInExternalFilesDir(service,
Environment.DIRECTORY_DOWNLOADS, "");
downloadReq
.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE
| DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
downloadIDs.add(downloadManager.enqueue(downloadReq));
Also please note that all the URLs are https, and the phone's android version is 4.1.2
Any idea?
Many Thanks!
Update: if I add the file name in this call:
downloadReq.setDestinationInExternalFilesDir(service,
Environment.DIRECTORY_DOWNLOADS, attachment.fileName);
the good name is displayed in the notification center.
You should register yourself to receive a broadcast when the file download is complete. Over there you can also grab the filename. This will need some changes to the code:
Retain the ID returned from enqueue call:
long enqueue = downloadManager.enqueue(downloadReq);
Register a receiver to get the broadcast:
getApplicationContext().registerReceiver(receiver, new IntentFilter(DownloadManager.ACTION_DOWNLOAD_COMPLETE));
declare the receiver:
BroadcastReceiver receiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if (!DownloadManager.ACTION_DOWNLOAD_COMPLETE.equals(action)) {
return;
}
context.getApplicationContext().unregisterReceiver(receiver);
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)) {
String uriString = c.getString(c.getColumnIndex(DownloadManager.COLUMN_LOCAL_URI));
Log.i(TAG, "downloaded file " + uriString);
} else {
Log.i(TAG, "download failed " + c.getInt(columnIndex));
}
}
}
};
Assuming a filename for download is not good practice. If you download it again without removing the previous one it will automatically get a suffix.
