                login_stat = s_ApiHandling.doLogin(m_Et_Username.getText()
                        .toString().trim(), m_Et_Password.getText()

                e.printStackTrace();
            }

            return stat;
        }


   @Override
 protected void onPostExecute(String status) {

                progress.dismiss();




            }

    }

@KingCobraa i tried progress bar code inside onPreExecute but not solve . — Jatinkumar Patel, Jul 10 '13 at 06:25
see if you are not doing anything with progressbar in your asnytask .how it ll diplay before your sending data. — Monty, Jul 10 '13 at 06:26
you want your progress dialog when you click on button, then you ll have to follow this rule ..onPreExecute ,doInBackground or if necessary onPostExecute — Monty, Jul 10 '13 at 06:28
can you do one thing create one thread inside your activity and show your dialog on onClick and inside the thread call your MyasynkTask with 2 sec sleep. — Monty, Jul 10 '13 at 06:46

You are probably doing too much in onPreExecute

Remove progress.cancel() from your doInBackground method and put it in to a onPostExecute method in your AsyncTask (like the second link you posted)

You shouldn't have anything talking to the UI in a background thread - that should all be done in pre/post execution.

you code should look like this:

AsyncTask<String, Void, String>()
{
    private ProgressDialog progressDialog = ProgressDialog.show(this, "", "Loading...");

    @Override
    protected void onPostExecute(String result)
    {
        progressDialog.dismiss();
    }

    @Override
    protected String[] doInBackground(String... params)
    {
        //ALL CODE GOES HERE.
    }
}

When you call the asynctask you must not use the get() method or the progress dialog won't work correctly.
