            AlertDialogFrgment af = AlertDialogFrgment();
              af.getFragmentManager()
            }

Hi Drashti,

You've mis-spelled the Fragment in the last task:

            public void onFailure(Request request, IOException e) {
              AlertDialogFragment af = new AlertDialogFragment();
              af.show(getFragmentManager(), "error_dialog");
            }

Also, you want to call the show method, which takes the two parameters, as above.

I hope that helps,

Steve.
