Fatal Exception: AsyncTask #1 - doInBackground()

I am having a exception that I can't resolved by the debugger log.
I am new to eclipse, so I would like you to help, it would be perfect.
So I got 2 webservices which are being called in a fragment to populate a listview and a spinner in that fragment.
The first webservice is called oncreateview(), and populates the spinner successfully.
The second webservice is called by a button click event, and will get another response (this one with two posts variables).
The Json response is correct, but it gets a exception, in the line(ScheduleList.add(Sche);), but strangely on other class (not this one).
I got two models classes, "Schedule" and "Teacher" to interact with each webservice.
Do you think that is something to do with two async functions on the same fragment?
private class GetTeachersInfo extends AsyncTask<String, Void, Void> {
#Override
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(getActivity());
pDialog.setMessage("A processar horários..");
pDialog.setCancelable(false);
pDialog.show();
}
#Override
protected Void doInBackground(String... arg) {
String professor = arg[0];
String dia_Semana = arg[1];
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("professor", professor));
params.add(new BasicNameValuePair("Dia_Semana", dia_Semana));
ServiceHandler jsonParser = new ServiceHandler();
String json = jsonParser.makeServiceCall(URL_TEACHERSINFO, ServiceHandler.POST, params);
Log.e("Response: ", "> " + json);
if (json != null) {
try {
JSONObject jsonObj = new JSONObject(json);
if (jsonObj != null) {
JSONArray schedules = jsonObj
.getJSONArray("horarios");
for (int i = 0; i < schedules.length(); i++) {
JSONObject ScheObj = (JSONObject) schedules.get(i);
Schedule Sche = new Schedule(ScheObj.getInt("Cod_Horario"),ScheObj.getString("T_Entrada"),
ScheObj.getString("T_Saida"),ScheObj.getString("Dia_Semana"),ScheObj.getString("Professor"),ScheObj.getString("Disciplina"),ScheObj.getString("Sala"),ScheObj.getString("Turma"));
ScheduleList.add(Sche);
}
}
} catch (JSONException e) {
e.printStackTrace();
}
} else {
Log.e("JSON Data", "Didn't receive any data from server!");
}
return null;
}

storing JSON to SharedReferences

I'm implementing JSON Parse in Android. The app connect to the url to retrieve JSON and return a String, everything work fine. Now I want to store JSON String to ShareReferences so user still can see the ListView if no internet connection. Here is my code
if (isInternetPresent) { //check internet connection
ServiceHandler sh = new ServiceHandler();
listDataHeader = new ArrayList<String>();
listDataChild = new HashMap<String, List<TVSchedModel>>();
// Making a request to url and getting response
jsonStr = sh.makeServiceCall(URL, ServiceHandler.GET); //connect to url and return a string
Editor editor = sharedpreferences.edit();
editor.putString("JSON", jsonStr);
editor.commit();
} else {
getActivity().runOnUiThread(new Runnable() {
public void run() {
Toast.makeText(getActivity(),
"Cannot connect to server", Toast.LENGTH_SHORT)
.show();
}
});
jsonStr = sharedpreferences.getString("JSON", "");
Log.i("JSON Shared", jsonStr);
}
try {
JSONObject jsonObj = new JSONObject(jsonStr);
// Getting JSON Array node
JSONArray chan = jsonObj.getJSONArray(TAG_CHANNEL);
for (int i = 0; i < chan.length(); i++) {
listDataHeader.add(chan.getJSONObject(i).getString(
"Channel"));
JSONArray sched = jsonObj.getJSONArray(chan
.getJSONObject(i).getString("Channel"));
List<TVSchedModel> result = new ArrayList<TVSchedModel>();
for (int k = 0; k < sched.length(); k++) {
result.add(convertSchedList(sched.getJSONObject(k)));
}
listDataChild.put(listDataHeader.get(i), result);
}
listAdapter.setHeaderList(listDataHeader);
return listDataChild;
} catch (Throwable t) {
t.printStackTrace();
}
If I have internet connection, the app runs fine. Then I turn off the internet, run the app again and get this error even I got the string back that show at Log.i(...)

What did I do wrong here?
Thanks

The error is coming from this line:
listDataHeader.add(chan.getJSONObject(i).getString("Channel"));
My bet is that listDataHeader is null when no connectivity is detected, and this is because you're just initializing this object in this block:
if (isInternetPresent) {
...
}
Simply initialize it outside (above) this block to let it be reachable even when there's no connectivity.

add this line after

that will solve the issue

You need to post the stack trace of the problem. You will find it in your logcat view. Also, on a sidenote:
runOnUiThread(new Runnable() {
public void run() {
This doesnt make any sense at all at this place because you are basically running a background thread, then you synchronize it and run it on the main thread. Depending on your settings, that won't work because Android does not allow network operations on the main / UI thread.
Edit after LogCat was added:
It's exactly what I mentioned. Android does not allow you to run network traffic on the UI thread. Remove that runOnUiThread stuff from the runOnBackground.
Now to set the data you can two one of two things:
Add the runOnUiThread part where you set the textView. Something like:
runOnUiThread(new Runnable() {
public void run() {
TextView tv = findViewById...
tv.setText(...
}
}
Return the object you need. This is actually how AsyncTask is supposed to work:
In your AsyncTask's runOnBackground, you'd do:
return product.getString(TAG_DESCRIPTION)
Then, in onPostExecute you get that String and set it to your TextViews.

Im doing some database work in my app, i want to pull all the locations from my web database and show it in my listview in the app. Ive created the "API" where the respons is Json.

Any help is much appreciated!

your URL string is wrong, you wrote it like:
Private static String url_all_products = "http://http://000100023.host56.com/db_all.php";
it should be:
Private static String url_all_products = "http://000100023.host56.com/db_all.php";
one http:// is enough ;)

initilize jParser in the onCreate
JSONParser jParser;
in onCreate
jParser = new JSONParser();
