downloading files using dropbox url android - android

I am trying to download files using dropbox url. I copied a code from Download a file with Android, and showing the progress in a ProgressDialog which uses DownloadManager class.
public void downloadFromDropBoxUrl(View view) {
//verfying if the downloadmanager is available first.
if (isDownloadManagerAvailable(getApplication())) {
String url = "https://www.dropbox.com/s/m4z5u9qstxdtbc3/AllExams22.pdf?dl=0";
DownloadManager.Request request = new DownloadManager.Request(Uri.parse(url));
request.setDescription("Some descrition");
request.setTitle("Some title");
// in order for this if to run, you must use the android 3.2 to compile your app
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
request.allowScanningByMediaScanner();
request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
}
request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, "my-map.pdf");
// get download service and enqueue file
DownloadManager manager = (DownloadManager) getSystemService(Context.DOWNLOAD_SERVICE);
manager.enqueue(request);
}
}
public static boolean isDownloadManagerAvailable(Context context) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.GINGERBREAD) {
return true;
}
return false;
}
It is working on achiving direct files with urls but this time I am trying to do it with dropbox share links but its not working out. I don't want to connect to dropbox api. I think it is useless. Is there any way I can download files directly from the dropbox url?

just replace
String url = "https://www.dropbox.com/s/m4z5u9qstxdtbc3/AllExams22.pdf?dl=0";
by:
String url = "https://dl.dropboxusercontent.com/s/m4z5u9qstxdtbc3/AllExams22.pdf";
Then:
final DownloadTask downloadTask = new DownloadTask(YourActivity.this);
downloadTask.execute(url);

Please see this link on how to download a shared file from Dropbox

Android DownloadManager error Unsuccessful

I'm working with Android downloadmanager. I got this error when passing url to downloadmanager. It's said that Download unsuccessfully, But I tried to use my browser then paste url . It's response file mp3. I don't know why downloadmanager did not recognize file to download.
Here is example URL to test:
http://htstar.design/mp3zing.php?q=320&link=http://mp3.zing.vn/bai-hat/Tired-Alan-Walker-Gavin-James/ZW7FA7WA.html
Update Here is my method download:
private void downloadFile(String url, String name) {
DownloadManager.Request request = new DownloadManager.Request(Uri.parse(url));
request.setTitle(name.replace(ext, ""));
request.setMimeType("audio/MP3");
request.setDescription(name);
request.setDestinationInExternalPublicDir("/Music", name);
request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
downloadManager.enqueue(request);
fabOpenDownload.setVisibility(View.VISIBLE);
}

Download Unsuccessful when using DownloadManager.Request to download the file from url

I'm trying to download the file from the server using DownloadManager but It fail's to download and say's Download unsuccessful, I have read that there is a issue with Download Manager in the below link
android-chrome-browser-unnecessarily-renames-names-types-of-downloaded-files so I tried to download the file by adding the RequestHeader to the DownloadManagerRequest using below method but nothing happened. please find the below code part of my Downloader class anyone please suggest me the right way to download the file from url using DownloadManager.
url:
http://-storage..net/95-****/95-3194.pdf?AWSAccessKeyId=T9YG9HWQC1LHE5G5VF38&Expires=1483443248&Signature=Z%2BkWzfEI2VawbCx%2F2Yto1kPcJKA%3D
Thanks
public void download(Uri uri) {
if (!isDownloading()) {
String fileName=getName(uri);
DownloadManager.Request request = new DownloadManager.Request(uri);
request.setTitle(fileName);
request.setNotificationVisibility(1);
request.allowScanningByMediaScanner();
request.addRequestHeader("Content-Type", "application/octet-stream");
request.addRequestHeader("Content-Disposition", "attachment; filename=\""+fileName.split("\\.")[0]+"."+fileName.split("\\.")[1].toUpperCase()+"\"");
String cookieContent = getCookieFromAppCookieManager(uri.getHost());
request.addRequestHeader("Cookie", cookieContent);
downloadId = downloadManager.enqueue(request);
register();
}
}
and below block returns the File name
private String getName(Uri uri) {
String name=uri.toString().split("jabord/")[1].split("\\?")[0];
return name;
}
returns the appcookie manager
public String getCookieFromAppCookieManager(String url) {
android.webkit.CookieManager cookieManager = android.webkit.CookieManager.getInstance();
if (cookieManager == null) {
return null;
}
String rawCookieHeader = null;
// Extract Set-Cookie header value from Android app CookieManager for this URL
rawCookieHeader = cookieManager.getCookie(url);
if (rawCookieHeader == null) {
return null;
}
return rawCookieHeader;
};
Please remove the headers and set the mimetype and then it will work. For example
public void download(Uri uri) {
if (!isDownloading()) {
String fileName=getName(uri);
DownloadManager.Request request = new DownloadManager.Request(uri);
request.setTitle(fileName);
request.setNotificationVisibility(1);
request.allowScanningByMediaScanner();
request.setMimeType("application/pdf");
Log.e("Extension with ","UpperCase-->"+"\""+fileName.split("\\.")[0]+"."+fileName.split("\\.")[1].toUpperCase()+"\"");
downloadId = downloadManager.enqueue(request);
register();
}
}
I was also facing the same issue. I solved it by removing the cookies.

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;
}

im not getting default file name when i download

i have created a webview app i added downloader inside which download the file end with m4a..the app downloads the file but file name changes...how can get title from the file...
public boolean shouldOverrideUrlLoading(WebView view, String url) {
// handle different requests for different type of files
// this example handles downloads requests for .m4a and .mp3 files
// everything else the webview can handle normally
if (url.endsWith(".m4a")) {
Uri source = Uri.parse(url);
// Make a new request pointing to the .apk url
DownloadManager.Request request = new DownloadManager.Request(source);
// appears the same in Notification bar while downloading
request.setDescription("Description for the DownloadManager Bar");
request.setTitle(getTitle());
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
request.allowScanningByMediaScanner();
request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
}
// save the file in the "Downloads" folder of SDCARD
request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, "filename");
// get download service and enqueue file
DownloadManager manager = (DownloadManager) getSystemService(Context.DOWNLOAD_SERVICE);
manager.enqueue(request);
}
else if(url.endsWith(".mp3")) {
// if the link points to an .mp3 resource do something else
}
// if there is a link to anything else than .m4a or .mp3 load the URL in the webview
else view.loadUrl(url);
return true;
}
});
This will give you your file name
final String[] separated = url.split("/");
final String myFile = separated[separated.length - 1];
It will split the url using the / character and you take the last element in the returned array.
Arrays are 0 based, so the last element is the one located at the vector's length - 1.
Put the above code just before this line: if (url.endsWith(".m4a")) {, where you want to get your file name.
Then, use it so:
request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, myFile);
Full code for downloading file inside webview without calling web-browser
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
// handle different requests for different type of files
// this example handles downloads requests for .m4a and .mp3 files
// everything else the webview can handle normally
if (url.endsWith(".m4a"))
{
Uri source = Uri.parse(url);
final String[] separated = url.split("/");
final String myFile = separated[separated.length - 1];
// Make a new request pointing to the .apk url
DownloadManager.Request request = new DownloadManager.Request(source);
// appears the same in Notification bar while downloading
request.setDescription("Description for the DownloadManager Bar");
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
request.allowScanningByMediaScanner();
request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
}
// save the file in the "Downloads" folder of SDCARD
request.setDestinationInExternalPublicDir(Environment.DIRECTORY_MUSIC, myFile);
// get download service and enqueue file
DownloadManager manager = (DownloadManager) getSystemService(Context.DOWNLOAD_SERVICE);
manager.enqueue(request);
}
else if (url.endsWith(".pdf"))
{
Uri source = Uri.parse(url);
final String[] separated = url.split("/");
final String myFile = separated[separated.length - 1];
// Make a new request pointing to the .apk url
DownloadManager.Request request = new DownloadManager.Request(source);
// appears the same in Notification bar while downloading
request.setDescription("Description for the DownloadManager Bar");
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
request.allowScanningByMediaScanner();
request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
}
// save the file in the "Downloads" folder of SDCARD
request.setDestinationInExternalPublicDir(Environment.DIRECTORY_MUSIC, myFile);
// get download service and enqueue file
DownloadManager manager = (DownloadManager) getSystemService(Context.DOWNLOAD_SERVICE);
manager.enqueue(request);
}
// if there is a link to anything else than .m4a or .mp3 load the URL in the webview
else view.loadUrl(url);
return true;
}
});

How to replace files in same location using Download manager in Android?

In my app I need to download some files(images,Pdf&txt). I am successful to save files through download manager in Downloads folder, But I want if file already exist in downloads folder and user again click on same file then it delete older one in download folder and replace with new file. Please let me know how it is possible?
My code:
database = new DMS_Database(Files_Folders_Activity.this);
if(!database.dididExist((doc_Id))) // if file does not exist then it will save file in the database and in downloads folder.
{
database.Save_Doc(doc_Id, name, url); //Database method
System.out.println("you are here: Save Files");
DownloadManager.Request request = new DownloadManager.Request(Uri.parse(url));
request.setTitle(name);
// in order for this if to run, you must use the android 3.2 to compile your app
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB)
{
request.allowScanningByMediaScanner();
request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
}
request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS + "/Downloads", name);
DownloadManager manager = (DownloadManager) getSystemService(Context.DOWNLOAD_SERVICE);
manager.enqueue(request);
}
else
{
database.update_Doc(Doc_Id,name,url);
//But if file already exist then How to delete file and again save on same location. I don't want duplicate file. Right now it is creating two websites also not updating database.
System.out.println("you are here: update files");
DownloadManager.Request request = new DownloadManager.Request(Uri.parse(url));
request.setTitle(name);
// in order for this if to run, you must use the android 3.2 to compile your app
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB)
{
request.allowScanningByMediaScanner();
request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
}
request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS + "/Downloads", name);
DownloadManager manager = (DownloadManager) getSystemService(Context.DOWNLOAD_SERVICE);
manager.enqueue(request);
}
database.close();
