I have a listview of PrivateFile objects which contain the fileId (int), fileName (String) and the fileContent (byte []). In order to share the file, I currently save the file first, open it again, and then I share it. In my opinion this is really semi-professional. Is there a way wherein I can only share the file (content)/byte array without saving it before? Or can I improve my code in general?

privateDocs.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() 
 @Override
 public boolean onItemLongClick(AdapterView<?> arg0, View arg1, int pos, long id) 
 try 
 PrivateFile selFile = (PrivateFile) arg0.getItemAtPosition(pos);

 File folder = new File(Environment.getExternalStorageDirectory() + "/myFolder");
 boolean success = true;
 if (!folder.exists()) 
 success = folder.mkdir();
 
 if (success) 
 //safe file in order to open it later
 File file = new File(folder.getAbsolutePath() + "/" + selFile.getFileName());
 FileOutputStream fos = new FileOutputStream(file.getAbsolutePath());
 fos.write(selFile.getFileContent());
 fos.close();


 Intent intentShareFile = new Intent(Intent.ACTION_SEND);

 if(file.exists()) 
 String newMimeType = MimeTypeMap.getSingleton().getMimeTypeFromExtension(MimeTypeMap.getFileExtensionFromUrl(Uri.fromFile(file).toString()));
 intentShareFile.setType(newMimeType);
 intentShareFile.putExtra(Intent.EXTRA_STREAM, Uri.parse("file://"+file.getAbsolutePath()));
 intentShareFile.putExtra(Intent.EXTRA_SUBJECT,
 "Sharing File...");
 intentShareFile.putExtra(Intent.EXTRA_TEXT, "Sharing File...");

 startActivity(Intent.createChooser(intentShareFile, "Share File"));
 

 else 
 throw new Exception("could not open folder");
 
 catch (Exception ex) 
 System.out.println("Err:" + ex.getMessage());
 
 return true;
 
 );
