   byte[] bytes; 
       byte[] data = result.getBytes("UTF-8"); 
       File outputFile = new File(mediaStorageDir.getAbsolutePath(), + "filename.zip"); 
       new FileOutputStream(outputFile); 
       bytes = Base64.decode(data, Base64.DEFAULT); 
       File filepath = new File(Environment.getExternalStorageDirectory(), "Folder/" + "filename.zip"); 
       OutputStream pdffos = new FileOutputStream(filepath); 
       pdffos.write(bytes); 
       pdffos.flush(); 
       pdffos.close();
