    1. @Override    
    2. public void onActivityResult(int requestCode, int resultCode, Intent data)    
    3. {    
    4.     if (requestCode == DBX_CHOOSER_REQUEST)    
    5.     {    
    6.         if (resultCode == Activity.RESULT_OK)    
    7.         {    
    8.             DbxChooser.Result result = new DbxChooser.Result(data);    
    9.             Log.d("main", "Link to selected file: " + result.getLink()); // Handle the result     
    10.         } else     
    11.         {    
    12.             // Failed or was cancelled by the user.     
    13.         }    
    14.     } else    
    15.     {
