                        response = LoginHttpClient
                                .executeHttpPost(

                        System.out.println(response);
                        JSONObject json = new JSONObject(response);
                        JSONArray jArray = json
                                .getJSONArray("customer");
                        for (int i = 0; i < jArray.length(); i++) {
                            JSONObject json_data = jArray
                                    .getJSONObject(i);
                            success = json_data.getString("success");
                            cus_id = json_data.getString("cus_id");
                            cus_name = json_data.getString("cus_name");
                        }
                        if (success.equals("1")) {
                            session = new SessionManager(
                                    getApplicationContext());
                            session.createLoginSessionRemMe(cus_id,
                                    cus_name);
                            Intent iv = new Intent(
                                    getApplicationContext(),
                                    Verify.class);
                            startActivity(iv);
                        } else {
                            // not valid email id or pass
                            Toast.makeText(getApplicationContext(),
                                    "Incorrect Mobile No",
                                    Toast.LENGTH_LONG).show();
                        }
                    } catch (Exception e) {
                    }
                }
            };
            thread.start();

        }

        else {
            // display message if text fields are empty
            Toast.makeText(getBaseContext(), "Mobile no is required",
                    Toast.LENGTH_SHORT).show();
        }
    }
});
       }}

where is `AsyncTask`?. You also display toast in thread. wrong — Raghunandan, Mar 21 '14 at 12:53
use asynctask and do your network operation in doInbackground and update ui in onpostexecute — Raghunandan, Mar 21 '14 at 13:01
@Raghunandan i am fetching data from server... when i simply used this code in avd 2.2 without thread it is work fine ....But when i used thread in code and run on avd 4.0 its not work — Amardeepvijay, Mar 21 '14 at 13:06
after 3.0 you can't do n/w opertion on the ui thread. Read the docs. — Raghunandan, Mar 21 '14 at 13:07
where is the asynctask involved in this you are creating a java thread for getting the data do you know the difference between a java thread and android asynctask thread — Pramod Yadav, Mar 21 '14 at 13:07
@Raghunandan plz check this link http://stackoverflow.com/questions/22560303/asynctask-not-working-when-fetching-data-from-server — Amardeepvijay, Mar 21 '14 at 13:36
