I want to download image from my webview, a notification comes and it downloads the file but when i go to Gallery then the file is not there.What i'm doing wrong ... ??
DownloadManager.Request request = new DownloadManager.Request(Uri.parse(geturl));
request.setTitle("File Download");
request.setDescription("File is being downloaded...");
request.allowScanningByMediaScanner();
request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
String nameOfFile = URLUtil.guessFileName(geturl, null, MimeTypeMap.getFileExtensionFromUrl(geturl));
request.setDestinationInExternalFilesDir(this,Environment.DIRECTORY_DCIM,nameOfFile);
DownloadManager manager = (DownloadManager)getApplication().getSystemService(Context.DOWNLOAD_SERVICE);
manager.enqueue(request);
While geturl is the Override url by which i am taking the url of an image.
public boolean shouldOverrideUrlLoading(WebView view, String url) {
//Get url for downloading
geturl = url;

Good day. I am creating an application that downloads a file from firebase. Next, this file will have to open in the application that is installed in advance on the phone. How can I find this file after installation and open it in a new application. Thanks for any answer. sorry for my English
Download code:
public void downloadFiles(Context context, String fileName, String fileExtension, String destinationDirectory, String url) {
DownloadManager downloadManager = (DownloadManager) context.getSystemService(Context.DOWNLOAD_SERVICE);
Uri uri = Uri.parse(url);
DownloadManager.Request request = new DownloadManager.Request(uri);
request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
request.setDestinationInExternalFilesDir(context, destinationDirectory, fileName + fileExtension);
downloadManager.enqueue(request);
What i tried.
open code:
public void openFile() {
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setType("file/*");
File download = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS),"king.mcpack");
intent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(download));
startActivity(Intent.createChooser(intent, "Open with"));
}
I try to download file inside a WebView. File is downloaded using browser but when I try to download through mobile WebView. It is download as .bin file. I checked this in android 10 device. It is working in below android 10. I was using Advance WebView library to open the WebView. I am using below code for that. Any help will be highly appreciated.
#Override
public void onDownloadRequested(String url, String suggestedFilename, String mimeType, long contentLength, String contentDisposition, String userAgent) {
DownloadManager.Request request = new DownloadManager.Request(
Uri.parse(url));
request.setMimeType(mimeType);
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,
mimeType));
request.allowScanningByMediaScanner();
request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
request.setDestinationInExternalPublicDir(
Environment.DIRECTORY_DOWNLOADS, URLUtil.guessFileName(
url, contentDisposition, mimeType));
DownloadManager dm = (DownloadManager) getSystemService(DOWNLOAD_SERVICE);
dm.enqueue(request);
Toast.makeText(getApplicationContext(), "Downloading File",
Toast.LENGTH_LONG).show();
Log.d("dsfgh", "onDownloadRequested: "+url);
}

Kindly Help
I'm developing a simple webview app using Android Studio. The webview app is booting a website that contains downloadable media files. For now, after downloading a file it save the file as fileName.
This is my Download manager
String myCurrentUrl;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
superWebView = findViewById(R.id.myWebView);
superProgressBar.setMax(100);
superWebView.loadUrl("http://www.hausadownload.blogspot.com");
superWebView.getSettings().setJavaScriptEnabled(true);
superWebView.setWebViewClient(new WebViewClient(){});
superWebView.setWebChromeClient(new WebChromeClient());
superWebView.setDownloadListener(new DownloadListener() {
#Override
public void onDownloadStart(String url, String userAgent, String contentDisposition, String mimetype, long contentLength) {
DownloadManager.Request myRequest = new DownloadManager.Request(Uri.parse(url));
myRequest.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, "fileName");
myRequest.allowScanningByMediaScanner();
myRequest.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
DownloadManager myManager = (DownloadManager) getSystemService(DOWNLOAD_SERVICE);
myManager.enqueue(myRequest);
Toast.makeText(MainActivity.this, "Your file is downloading...", Toast.LENGTH_SHORT).show();
}
});
}
I don't want it to be saving all files with the name "fileName". I want it to be saving files with their default names
You should somehow be able to get the file name from the url like so:
String fileName = url.substring(url.lastIndexOf('/') + 1, url.length());
Then just pass that in this line instead of hardcoded String "filename":
myRequest.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, fileName);
I am using DownloadManager but it puts the download somewhere I don't know. I want to download the file in a specific folder like "mp3" in sdcard.
Here is the code I am using :
private class HelloWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView webview, String url)
{
if(url.endsWith(".mp3") || !url.startsWith("http://xnm")) {
String servicestring = Context.DOWNLOAD_SERVICE;
DownloadManager downloadmanager;
downloadmanager = (DownloadManager) getSystemService(servicestring);
Uri uri = Uri.parse(url);
DownloadManager.Request request = new Request(uri);
Long reference = downloadmanager.enqueue(request);
setProgressBarIndeterminateVisibility(false);
}
else {
mWebView.loadUrl(url);
setProgressBarIndeterminateVisibility(true);
}
return true;
}
#Override
public void onPageFinished(WebView webview, String url){
super.onPageFinished(webview, url);
setProgressBarIndeterminateVisibility(false);
}
}
Thanks in advance !!
Use
File file = new File(Environment.getExternalStorageDirectory(), "mp3")
request.setDestinationUri(Uri.fromFile(file));
to set the download path
Actually I got it working after searching a lot and here it is the code to add in existing.
File folder = new File(Environment.getExternalStorageDirectory() + "/any");
if (!folder.exists()) {
folder.mkdir();
}
DownloadManager.Request request = new DownloadManager.Request(Uri.parse(url));
request.setDestinationInExternalPublicDir("/Download/Global Mp3", nameOfFile);
And we need this permission in manifest file
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
Thats it !!! Maybe it will help someone else
request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, fileName);
