                try {
                    JSONObject jobj = new JSONObject(response);
                    JSONObject jobjHRM = jobj.getJSONObject("HRM");
                    int status = jobjHRM.getInt("StatusCode");
                    if (status == 200) {
                        if (jobj.getJSONObject("Data").getBoolean("result") == true) {
                            login_info_editor.putInt("id", jobj.getJSONObject("Data").getInt("id"));
                            login_info_editor.putString("username", txtlayoutid.getEditText().getText().toString());

Try to configure retry policy. Give a large timeout and try,

int socketTimeout = 30000; // 30 seconds. You can change it
RetryPolicy policy = new DefaultRetryPolicy(socketTimeout,                 
DefaultRetryPolicy.DEFAULT_MAX_RETRIES,     
DefaultRetryPolicy.DEFAULT_BACKOFF_MULT);

postRequest.setRetryPolicy(policy);
AppController.getInstance().addToRequestQueue(postRequest);
