try it this way...

sorry can't comment but what you getting at post execute from background task is file_url as string which is your param at on post execute......i think if you are getting result all params like first name ,lastName etc then you needed to pass jsonObject at onpost Execute
so you can parse at onPostExecute...your jsonResult and display it in textbox
Problem is in you current code is
txtFname.setText("Firstname: " + firstname);
in which firstName is from
String firstname = jb.getString("firstname");
JSONObject jb= user.getJSONObject(0);
JSONArray user = hay.getJSONArray("user");
JSONObject hay = new JSONObject ((Map) json);
JSONObject json = null;
i have reversed it so you can find problem here json is null so here is problem and pls try logging at each point and let we know so we and you can have exact idea....or give us json format...

the problem is with your this code segment:
JSONObject json = null;
JSONObject hay = new JSONObject((Map) json);
JSONArray user = hay.getJSONArray("user");
JSONObject jb = user.getJSONObject(0);
String firstname = jb.getString("firstname");
String middlename = jb.getString("middlename");
String lastname = jb.getString("lastname");
here what you are doing is: making another JSONObject as
JSONObject json = null;
that is creating a variable with local scope, the local variable will have more priority than global, that you understood. actually you need the json which is created from doInBackgrounnd(). so pass the json from doInBackground to onPostExecute: it is simple,
change the statements:
return json.getString(TAG_MESSAGE); => return json;
return json.getString(TAG_MESSAGE); => return json;
also change the type of doInBackground to JSONObject and avoid making a new local JSONObject and trying to get datafrom that (bcz it is null you initialized with).
JSONObject json = null; //remove this
JSONObject hay = new JSONObject((Map) json); //remove this
JSONArray user = hay.getJSONArray("user"); // change hay to json
also change the
protected void onPostExecute(String file_url)// to protected void onPostExecute(JSONObject json)

here is your changed code, let me know what you are getting if some errors.

make a string from AsyncTask not null in onCreate

I have a problem i need the token to transfer it to my SessionManagement class to compare it with the saved token , but in my onCreate it's always null ,i need a workaround to make my token not null in oncreate
please help.
here is my code
private static final String LOGIN_URL = "http://baymd.myterranet.com/api/auth";
private static final String TAG_SUCCESS = "code";
private static final String TAG_MESSAGE = "message";
private static final String TAG_DATA = "data";
private static final String TAG_TOKEN = "access_token";
JSONParser jsonParser = new JSONParser();
private EditText user, pass;
private Button mSubmit;
private ProgressDialog pDialog;
private String token, none,SavedToken;
SesionManagement session;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
session=new SesionManagement(getApplicationContext());
HashMap<String, String> tokens = session.getUserDetails();
SavedToken = tokens.get(session.KEY_NAME);
if(token==null) {//This line
Log.d("TOKEN ====== ", "NULLL");
}
session.checkLogin(token, SavedToken);
user = (EditText) findViewById(R.id.inputEmail);
pass = (EditText) findViewById(R.id.inputPass);
mSubmit = (Button) findViewById(R.id.loginBtn);
mSubmit.setOnClickListener(this);
}
#Override
public void onClick(View v) {
new AttemptLogin().execute();
}
class AttemptLogin extends AsyncTask<String, String, String> {
#Override
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(Login.this);
pDialog.setMessage("Attempting login...");
pDialog.setIndeterminate(false);
pDialog.setCancelable(true);
pDialog.show();
}
#Override
protected String doInBackground(String... args) {
int success;
String username = user.getText().toString();
String password = pass.getText().toString();
try {
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("email", username));
params.add(new BasicNameValuePair("password", password));
JSONObject json = jsonParser.makeHttpRequest(
LOGIN_URL, "POST", params, none);
success = json.getInt(TAG_SUCCESS);
if (success == 200) {
JSONObject c = json.getJSONObject(TAG_DATA);
token = c.getString(TAG_TOKEN);//The token wich is null in oncreate
Intent i = new Intent(Login.this, NavDraver.class);
i.putExtra("cjson", c.toString());
finish();
startActivity(i);
return json.getString(TAG_MESSAGE);
} else {
Log.d("Login Failure!", json.getString(TAG_MESSAGE));
json.getString(TAG_MESSAGE);
return json.getString(TAG_MESSAGE);
}
} catch (JSONException e) {
e.printStackTrace();
}
return null;
}
#Override
protected void onPostExecute(String s) {
session.createLoginSession(token);
Log.d("SAVED TOKEN",SavedToken);
pDialog.dismiss();
}
}
}

Try this:
token = c.optString(TAG_TOKEN, yourDefaultValueHere);
if(token == null){
token = ""; // or whatever you want to init here
}
Hope it helps.

I will recommend to call the intent in onPostExecute of AsyncTask. Also store the text of the button in a string before going into doInBackground. The doInBackground is a seperate thread and can't communicate with Main UI Thread.

as berserk said,the doInBackground is a seperate thread that cant communicate with main UI Thread,so, as my recommedn,you should startActivity() in the onPostExecute.
just change to below
private class CreatePerson extends AsyncTask<String, String, String>{
#Override
protected void onPreExecute() {
super.onPreExecute();
mProgressDialog = new ProgressDialog(MainActivity.this);
mProgressDialog.setMessage("Creating Product..");
mProgressDialog.setIndeterminate(false);
mProgressDialog.setCancelable(true);
mProgressDialog.show();
//String select = null;//member var of outside class
switch (gender.getCheckedRadioButtonId())
{
case R.id.mr:
select="Mr.";
break;
case R.id.mrs:
select="Mrs.";
default:
break;
}
String firstname = inputfirstname.getText().toString();
String middlename = inputmiddlename.getText().toString();
String lastname = inputlastname.getText().toString();
String aliasname = inputaliasname.getText().toString();
String city = inputcitybirth.getText().toString();
//List<NameValuePair> params = new ArrayList<NameValuePair>();//member var of outside class
params.add(new BasicNameValuePair("FirstName", firstname));
params.add(new BasicNameValuePair("MiddleName", middlename));
params.add(new BasicNameValuePair("LastName", lastname));
params.add(new BasicNameValuePair("AliasName", aliasname));
params.add(new BasicNameValuePair("Gender", select));
params.add(new BasicNameValuePair("CityBirth", city));
params.add(new BasicNameValuePair("DateBirth", date.getSelectedItem().toString()));
params.add(new BasicNameValuePair("MonthBirth", month.getSelectedItem().toString()));
params.add(new BasicNameValuePair("YearBirth", year.getSelectedItem().toString()));
}
#Override
protected String doInBackground(String... args) {
// TODO Auto-generated method stub
// JSONObject json = null//member var of outside class
json = jsonParser.makeHttpRequest(url_create_person, "POST", params);
return null;
}
protected void onPostExecute(String file_url) {
// dismiss the dialog once done
if(mProgressDialog != null && mProgressDialog.isShow()){
mProgressDialog.dismiss();
}
Log.d("Create Response", json.toString());
try {
int success = json.getInt(TAG_SUCCESS);
if (success == 1) {
String id = ((Button) findViewById(R.id.btnsnextnewperson)).getText().toString();
Intent i = new Intent(getApplicationContext(),CreateUser.class);
i.putExtra(TAG_ID, id);
startActivity(i);
finish();
} else {
