Download file in android studio with the original file name

How to write the code to download file in android studio with the original file name?
I am trying to create a very simple webview mobile android application as I am a beginner in this field. I am almost done but I am stuck at a problem. It is working perfectly with .pdf but it is saving .lrc files with .txt extension.
My code is:
MainActivity.java
webview.setDownloadListener(new DownloadListener() {
#Override
public void onDownloadStart(String url, String userAgent, String contentDisposition, String fileExtenstion, long contentLength) {
DownloadManager.Request request = new DownloadManager.Request(Uri.parse(url));
MimeTypeMap.getFileExtensionFromUrl(url);
String cookies = CookieManager.getInstance().getCookie(url);
request.addRequestHeader("cookie",cookies);
request.addRequestHeader("User-Agent",userAgent);
request.setDescription("Downloading file....");
request.setTitle(URLUtil.guessFileName(url,contentDisposition,fileExtenstion));
request.allowScanningByMediaScanner();
request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, URLUtil.guessFileName(url, contentDisposition, fileExtenstion));
DownloadManager dm = (DownloadManager) getSystemService(DOWNLOAD_SERVICE);
dm.enqueue(request);
Toast.makeText(getApplicationContext(),"Downloading File",Toast.LENGTH_SHORT).show();
}
}); ```
**AndroidManiFest.xml**
```
Can you guys help me to make it right please.

Download Path of file from a website loaded in WebView Android

I am working on a project where use case is we have to load a web page url in webview which has a button when user clicks on button it will download pdf file. And we have to open that downloaded PDF. currently, i am not finding which path does the file got Downloaded.

You can use the webview download listener and set the path manually using DownloadManager.
An example where the file will be download to /Downloads folder would be:
myWebview.setDownloadListener(new DownloadListener() {
#Override
public void onDownloadStart(String url, String userAgent, String contentDisposition, String mimeType, long contentLength) {
DownloadManager.Request request = new DownloadManager.Request(Uri.parse(url));
request.setMimeType(mimeType);
request.allowScanningByMediaScanner();
String fileExtenstion = MimeTypeMap.getFileExtensionFromUrl(url);
String filename = URLUtil.guessFileName(url, contentDisposition, fileExtenstion);
request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, filename);
DownloadManager dm = (DownloadManager) getSystemService(DOWNLOAD_SERVICE);
dm.enqueue(request);
}
});
Also add the below permissions to AndroidManifest.xml .
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

Android Webview Download manager To Download PDF Files

I have an android application which uses a single WebView which loads a website inside it.
setContentView(R.layout.activity_main);
WebView webView = (WebView) this.findViewById(R.id.webview);
Then i used download manager to Download my files from server
webView.setDownloadListener(new DownloadListener() {
public void onDownloadStart(String url, String userAgent, String contentDisposition, String mimetype, long contentLength) {
// ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, REQUEST_CODE);
//for downloading directly through download manager
DownloadManager.Request request = new DownloadManager.Request(Uri.parse(url));
request.allowScanningByMediaScanner();
Environment.getExternalStorageDirectory();
getApplicationContext().getFilesDir().getPath(); //which returns the internal app files directory path
request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, "download");
DownloadManager dm = (DownloadManager) getSystemService(DOWNLOAD_SERVICE);
dm.enqueue(request);
}
});
when i try to download a file which is created dynamically by the website i get to download the websites HTML instead of the PDF.
webView.loadUrl("http://bookboon.com/");
Thanks in Advance

Actually that HTML page is showing the login page for authentication. So you need a session key which is inside the cookies of that website.
So you need to add three lines in onDownloadListener
webView.setDownloadListener(new DownloadListener() {
public void onDownloadStart(String url, String userAgent, String contentDisposition, String mimetype, long contentLength) {
// ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, REQUEST_CODE);
//for downloading directly through download manager
DownloadManager.Request request = new DownloadManager.Request(Uri.parse(url));
//This three lines will do your work
CookieManager cookieManager = CookieManager.getInstance();
String cookie = cookieManager.getCookie("<Your website url>"); // which is "http://bookboon.com"
request.addRequestHeader("Cookie", cookie);
//................................................
request.allowScanningByMediaScanner();
Environment.getExternalStorageDirectory();
getApplicationContext().getFilesDir().getPath(); //which returns the internal app files directory path
request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, "download");
DownloadManager dm = (DownloadManager) getSystemService(DOWNLOAD_SERVICE);
dm.enqueue(request);
}
});

webview, download file on finish prepared document

I'm using webview android.
I want to do basically is to download a file, when the server offers it to me.
Whatever happens, that until just the last post, "in a browser" does not give you the option to save the file.
Therefore, when I try to save the file in android, I never get save.
As you can see, it does not end until the last post, the browser does not have the file. It seems a method asynchronous
webView.setDownloadListener(new DownloadListener()
{
public void onDownloadStart(String url, String userAgent, String contentDisposition, String mimetype, long contentLength)
{
//for downloading directly through download manager
Request request = new Request(Uri.parse(url));
request.allowScanningByMediaScanner();
request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, "download");
DownloadManager dm = (DownloadManager) getSystemService(DOWNLOAD_SERVICE);
dm.enqueue(request);
}
});
And these code, but can't open in browser because have Get and Post request to download PDF.
webView.setDownloadListener(new DownloadListener() {
public void onDownloadStart(String url, String userAgent,
String contentDisposition, String mimetype,
long contentLength) {
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(url));
startActivity(i);
}
});
I can not think of other ways

How to change default download location in android

I have a webview and i want to download files to the sdcard custom folder when user clicking download link from webview.
I'm using the following code for downloading file from webview:
webView.setDownloadListener(new DownloadListener() {
public void onDownloadStart(String url, String userAgent,
String contentDisposition, String mimetype,
long contentLength) {
strurl = url;
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(url));
startActivity(i);
}
It works properly. But it directly downloads to the /sdcard/download/ folder. But i want it to download to some other folder on the sdcard. How can I accomplish this?
