Try using download manager  which can help you download everything you want and save you time   Check those to options   Option 1 -    mWebView setDownloadListener new DownloadListener             public void onDownloadStart String url  String userAgent                  String contentDisposition  String mimetype                  long contentLength     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                                Option 2 -   if mWebview getUrl   contains   mp3      Request request   new Request                          Uri parse url                    request allowScanningByMediaScanner                    request setNotificationVisibility DownloadManager Request VISIBILITY VISIBLE NOTIFY COMPLETED                   request setDestinationInExternalPublicDir Environment DIRECTORY DOWNLOADS   download        You can change the name of the downloads  by changing  download  to everything you want  such as the mWebview title                    DownloadManager dm    DownloadManager  getSystemService DOWNLOAD SERVICE                   dm enqueue request

If you don t want to use a download manager then you can use this code webView setDownloadListener new DownloadListener                   Override             public void onDownloadStart String url  String userAgent  String contentDisposition                       String mimetype  long contentLength                     String fileName   URLUtil guessFileName url  contentDisposition  mimetype                    try                       String address   Environment getExternalStorageDirectory   getAbsolutePath      quot   quot                                Environment DIRECTORY DOWNLOADS    quot   quot                                fileName                      File file   new File address                       boolean a   file createNewFile                         URL link   new URL url                       downloadFile link  address                      catch  Exception e                        e printStackTrace                                                  public void downloadFile URL url  String outputFileName  throws IOException            try  InputStream in   url openStream                 ReadableByteChannel rbc   Channels newChannel in                FileOutputStream fos   new FileOutputStream outputFileName                 fos getChannel   transferFrom rbc  0  Long MAX VALUE                           do your work here         This will download files in the downloads folder in phone storage  You can use threads if you want to download that in the background  use thread alive   and timer class to know the download is complete or not   This is useful when we download small files  as you can do the next task just after the download
