You cannot update UI inside doInBackground.Do this to show toast

getActivity().runOnUiThread(new Runnable() {

            @Override
            public void run() {
                Toast.makeText(getApplicationContext(),
                        "Server too busy. Please try after sometime.",
                        Toast.LENGTH_LONG).show();

            }
        });

It will solve your problem

because Toast runs on Ui thread and Async task starts new thread so it gives exception – Chandrakant Dvivedi Dec 23 '15 at 10:21
