Can't get the value from doInBackGround() process at onPostExecute()

I'm using AsyncTask to insert, update and delete data from database. I used this code to insert, update, delete and it works fine. But when I want to use select, and show the data at EditText, I can't get the value from doInBackground() to the onPostExecute() and it shows nothing.
Here's my code :
MenuUtama.java
public class MenuUtama extends Activity {

deskripsi = (EditText) findViewById(R.id.editDes);
cek = (Button) findViewById(R.id.btnCek);
insert = (Button) findViewById(R.id.buttonInsert);

It is because you don't return any value from the doInBackground() (always return null) and you are not using the 'string' in the onPostExecute(String result) formal parameter. Garbage-In-Garbage-Out

your doInBackground() returns just a string return kode_d; and then in your onPostExecute(String result) (which expects a String) you use the kode_d which is null.
If you want all of those values to be returned create an ArrayList(), return it at the end doInBackground() and get it in onPostExecute(ArrayList result) with an iteration and pass it to you textviews.
Even better create an object and add the values to each field. Your fields are the kode_d, nama_d, harga_d, des_d
this is what the onPostExecute does
/**
* <p>Runs on the UI thread after {#link #doInBackground}. The
* specified result is the value returned by {#link #doInBackground}.
* To better support testing frameworks, it is recommended that this be
* written to tolerate direct execution as part of the execute() call.
* The default version does nothing.</p>
*
* <p>This method won't be invoked if the task was cancelled.</p>
*
* #param result The result of the operation computed by {#link #doInBackground}.
*
* #see #onPreExecute
* #see #doInBackground
* #see #onCancelled(Object)

JSON: Value of type java.lang.String cannot be converted to JSONObject

I'm trying to program an app to send a String to a service. A friend of mine has a service to receive the data.
Logcat shows this error: "org.json.JSONException: Value FIRST of type java.lang.String cannot be converted to JSONObject"

I read questions to other people with the same problem. The solution seemed to be to add a "{" at the beginning of the json String and a "}" at the end, but it didn't work to me. I tried changing this:
String json = serviceClient.makeServiceCall(URL_NEW_PREDICTION,
ServiceHandler.POST, params);
to this:
String json = "{" + serviceClient.makeServiceCall(URL_NEW_PREDICTION,
ServiceHandler.POST, params) + "}";
but the I got this error:
"org.json.JSONException: Expected ':' after FIRST at character 9 of {FIRST DATA New record created successfully}"

You're receiving back a string that is not able to be parsed to JSON. You can't just make something JSON by adding braces, it needs to adhere to proper JSON formatting. This site shows some good examples of what that means.
Specifically, the parser is telling you that having a space after FIRST isn't okay without having quotes around it...but just adding that won't fix the issue, the problem is more deep than that.

How to access json array that is passed from restful web service in android?

I have successfully created a rest web service and it returns jsonarray which has two fields
id and city from data base.
My resr web service is
#GET
#Path("city")
#Produces("application/json")
public String getJson() {
PropertyPojo propojo=null;
ArrayList cityList = new ArrayList();
JSONArray list = new JSONArray();
Map m1 = new LinkedHashMap();
List l1 = new LinkedList();
String jsonString = null;
try{
cityList=PDao.CityList();
Iterator it=cityList.iterator();
while(it.hasNext())
{
propojo=(PropertyPojo)it.next();
m1.put(propojo.getKeyid(),propojo.getKeyvalue());
}
}catch(Exception e){
}
l1.add(m1);
jsonString = JSONValue.toJSONString(l1);
return jsonString;
}

Its better to create Model class and then you can parse the response with gson.
For example,
Imagine that you have your response with two strings Name and Mail. Create a model with two strings.
public class Sample{
public Sample()
{
}
#SerializedName("Name")//if needed
String name;
#SerializedName("Email")//if needed
String email;
public void set(String name) {
this.name = name;
}
public String getName() {
return name;
}
public void set(String email) {
this.email = email;
}
public String getEmail() {
return email;
}
}
Then parse your response with gson.
Sample sample = gson.fromJson(jsonRes.toString(), Sample.class);
Then you can access the members of the object sample. Change the Sample class as you needed(with the array of strings and int. You can use ArrayList instead of Array)

String[] city= {};
String[] id= {};
JSONArray jsonDetailsObj = json.getJSONArray("cityList");
JSONObject jsonLoop = null;
int noOfPoints = jsonDetailsObj.length();
city= new String[noOfPoints];
id= new String[noOfPoints];
for (int i=0 ; i < noOfPoints ; i++)
{
jsonLoop=jsonDetailsObj.getJSONObject(i);
city [i] = jsonLoop.getString("CityName");
id[i] = jsonLoop.getString("ID");
}

Android Error Returning a null value from Thread

I created this application to get the wether details to my app.
I have a GetWeather Class in my Android App whre i have GetWeather method which returns a string. but when i try to get value form that class which consist of a thread. i always get a null value. Please refer my code kindly and tell me where i got wrong. Thank you

while (weather != null) {
}

The condition while(whether != null) should be while(whether == null) to wait for a Thread to complete its task. But it will wait on UI Thread which may result in ANR error.
Instead use AsyncTask and get the result in onPostExecute()...
and with respect to your comments, This may help you.
public class WeatherTask extends AsyncTask<String, Void, String[]> {
#Override
protected String[] doInBackground(String... params) {
String city = params[0];
String state = params[1];
city = city.replaceAll(" ", "_");
// construct post URL
final String GET_WEATHER_URL = WEATHER_URL + state + "/" + city
+ ".json";
String request = GET_WEATHER_URL;
HttpResponse rp = null;
JSONObject jObject = null;
try {
HttpClient httpclient = new DefaultHttpClient();
httpclient.getParams().setParameter(
CoreProtocolPNames.PROTOCOL_VERSION,
HttpVersion.HTTP_1_1);
HttpGet request1 = new HttpGet(
"http://api.wunderground.com/api/key/conditions/q/CA/Anuradhapura.json");
HttpResponse response = httpclient.execute(request1);
HttpEntity resEntity = response.getEntity();
String _response = EntityUtils.toString(resEntity);
jObject = new JSONObject(_response);
JSONObject current_observation = jObject
.getJSONObject("current_observation");
String temperature_string = current_observation
.getString("temperature_string");
String weather = current_observation.getString("weather");
Log.i("..............", "" + weather);
Log.i("..............", "" + temperature_string);
String icon_url = current_observation.getString("icon_url");
String weather_icon = get_weather_icon(icon_url);
String[] out = new String[]{weather,weather_icon,temperature_string};
return out;
} catch (Exception exception) {
}
return null;
}
#Override
protected void onPostExecute(String[] result) {
if(result != null) {
String weather = result[0];
String weather_icon = result[1];
String temperature_string = result[2];
}
}
}
and start this task in onButtonClick() like
new WeatherTask().execute("CA","Anuradhapura");
