For those who are getting Error Unknown URI  content   downloads public downloads  I managed to solve this by getting a hint given by  Commonsware in this answer  I found out the class FileUtils on GitHub   Here InputStream methods are used to fetch file from Download directory       DownloadsProvider             else if  isDownloadsDocument uri                      final String id   DocumentsContract getDocumentId uri                    if  id    null  amp  amp  id startsWith  raw                           return id substring 4                                      String   contentUriPrefixesToTry   new String                             content   downloads public downloads                            content   downloads my downloads                            content   downloads all downloads                                      for  String contentUriPrefix   contentUriPrefixesToTry                        Uri contentUri   ContentUris withAppendedId Uri parse contentUriPrefix   Long valueOf id                        try                           String path   getDataColumn context  contentUri  null  null                           if  path    null                                return path                                                  catch  Exception e                                           path could not be retrieved using ContentResolver  therefore copy file to accessible cache using streams                 String fileName   getFileName context  uri                   File cacheDir   getDocumentCacheDir context                   File file   generateFileName fileName  cacheDir                   String destinationPath   null                  if  file    null                        destinationPath   file getAbsolutePath                        saveFileFromUri context  uri  destinationPath                                      return destinationPath

The exception is caused by disabled Download Manager  And there is no way to activate deactivate Download Manager directly  since it s system application and we don t have access to it   Only alternative way is redirect user to settings of Download Manager Application   try          Open the specific App Info page       Intent intent   new Intent android provider Settings ACTION APPLICATION DETAILS SETTINGS        intent setData Uri parse  package      com android providers downloads          startActivity intent      catch   ActivityNotFoundException e          e printStackTrace            Open the generic Apps page       Intent intent   new Intent android provider Settings ACTION MANAGE APPLICATIONS SETTINGS        startActivity intent
