You should write code, which modify event thread, in onPostExecute(), or onPreExecute(), or onPublishedProgress() methods, not in doInBackground() methods.

I am working on application in which i want one output as shown in below image.
for that i tried following code:
private ListView notification_listview;

Whenever I am trying to remove an object from JsonArray , It shows there is no such method exists. My target API version is 8. I look up for other questions regarding this but could not find a suitable solution. please help me with this.

Do you really want a headache supporting a bit amount of so old devices?
Nevertheless, use this:
JSONObject jso= new JSONObject(resString);
JSONArray jsonArray = jso.getJSONArray("jobmasterto");
Log.e("jason array is this", ""+jsonArray);
ArrayList<Integer> i_ar = new ArrayList<Integer>();
for (int i = 0; i < jsonArray.length(); i++) {
if (jsonArray.getJSONObject(i).getString("jobName").equals(null) || jsonArray.getJSONObject(i).getString("jobName").equals("null") || jsonArray.getJSONObject(i).getString("jobName").equals("")) {
Log.e("Output : : ", jsonArray.getJSONObject(i).getString("jobName"));
i_ar.add(i);
}
}
JSONArray jsono = new JSONArray();
int len = jsonArray.length();
if (jsonArray != null) {
for (int i=0;i<len;i++)
{
//Excluding the item at position
if (i_ar.indexOf(i) == -1)
{
list.put(jsonArray.get(i));
}
}
}
if(jsono.length()>=0)
{
//.... continue...
I am trying to fetch some data from Web Server through JSON. I am using asynctask to do so. Normally it is taking 5-10 seconds to be shown in my ListView.
Hence I want to put spinner progress bar. My code is working fine only problem is the progress bar is not visible.
MyActivity code to call asyntask
try{
JSONObject output = new AsyncTaskJsonParse(this,status, A, B, city).execute().get();
try {
JSONObject output = new AsyncTaskJsonParse(ListViewDisplay.this,status, bgrp, antigen, city).execute().get();
JSONObject src = output.getJSONObject("data");
String flag = output.getString("success");
String flagmsg = output.getString("message");
if (flag == "1") {
JSONArray jarr_name = new JSONArray(src.getString("name"));
JSONArray jarr_fathername = new JSONArray(src.getString("fathername"));
JSONArray jarr_moh = new JSONArray(src.getString("moh"));
JSONArray jarr_city = new JSONArray(src.getString("city"));
JSONArray jarr_phone = new JSONArray(src.getString("phone"));
int n = jarr_name.length();
name_array = new String[n];
fathername_array = new String[n];
moh_array = new String[n];
phone_array = new String[n];
city_array = new String[n];
for (int i = 0; i < n; i++) {
name_array[i] = (String) jarr_name.get(i);
fathername_array[i] = (String) jarr_fathername.get(i);
moh_array[i] = (String) jarr_moh.get(i);
phone_array[i] = (String) jarr_phone.get(i);
city_array[i] = "Vadodara";
Log.d("Inside StringArray", i + "");
}
String msg = src.getString("name");
list = (ListView) findViewById(R.id.listView);
CustomListAdapter custAdaptor = new CustomListAdapter(this, name_array, fathername_array, mohalla_array, city_array, phone_array);
list.setAdapter(custAdaptor);

In my log I can see the message "In preexecution Showing 2". And the appliaction is working as expected but the Spinner progressbar is not visible.
Note: I did not add any progressbar component in any xml file. Does i need to add it? if yes then where and how?

I suspect your problem is that your AsyncTask finishes immediately as parse.getJSONFromUrl... is also Async. So whats happening is that progress.dismiss(); in onPostExecute invoked also immediately.
Try removing progress.dismiss(); from onPostExecute and see what happens
This should work. But without the progress.setMessage("Processing...");
You can still set that.

I am converting my HTTP calls to asynchronous calls from synchronous ones. Because the connection is running in the background the data isn't there when I originally set my list adaptor. How can I get the list adaptor to update after my HTTP call? I've tried a few things like not setting the adaptor until data gets sent back and setting the adaptor again, but nothing has worked. Here's my current oncreate code
protected void onCreate(Bundle savedInstanceState) {
overridePendingTransition(R.layout.anim_out,R.layout.anim_in);
setTheme(R.style.Theme_D_theme);
setContentView(R.layout.news_fragment);
super.onCreate(savedInstanceState);
text = (TextView) this.findViewById(R.id.nomore);
list = (ListView) this.findViewById(R.id.newslist);
list.setDividerHeight(2);
new MyAsyncTask().execute("THIS");
list.setOnItemClickListener(this);
list.setCacheColorHint(Color.WHITE);
adapter = new SimpleAdapter(this, x, R.layout.drill1_listview,
new String[] {"title","content","distance", "image"},
new int[] {R.id.title, R.id.content, R.id.distance, R.id.image} );
}
And my AsyncTast
private class MyAsyncTask extends AsyncTask<String, Integer, Double>{
#Override
protected Double doInBackground(String... params) {
// TODO Auto-generated method stub
postData(params[0]);
return null;
}
protected void onPostExecute(Double result){
//pb.setVisibility(View.GONE);
Toast.makeText(getApplicationContext(), "command sent", Toast.LENGTH_LONG).show();
}
protected void onProgressUpdate(Integer... progress){
//pb.setProgress(progress[0]);
}
public void postData(String valueIWantToSend) {
ThreadPolicy tp = ThreadPolicy.LAX;
StrictMode.setThreadPolicy(tp);
HttpClient httpclient = new DefaultHttpClient();
String type = getIntent().getExtras().getString("type");
HttpGet httppost = new HttpGet("http://myip.../all?latitude=42.12345&longitude=-76.2154");
InputStream inputStream = null;
try {
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
String JSONstring = EntityUtils.toString(entity);
Log.w("HTTPRESPONSE", JSONstring);
//Toast.makeText(this, JSONstring, Toast.LENGTH_SHORT).show();
if (!(JSONstring.equals(" 0"))) {
JSONArray array = new JSONArray(JSONstring);
for (int i = 0; i < array.length(); i++) {
JSONObject row = array.getJSONObject(i);
HashMap<String,String> temp = new HashMap<String,String>();
String thisid = row.getString("id");
ider.add(thisid);
String starthold = row.getString("start_time");
start.add(starthold);
String endhold = row.getString("end_time");
end.add(endhold);
String latitudehold = row.getString("latitude");
latitude.add(latitudehold);
String longitudehold = row.getString("longitude");
longitude.add(longitudehold);
String addresshold = row.getString("street");
address.add(addresshold);
String title = row.getString("company");
company.add(title);
temp.put("title", title);
String distance_hold = row.getString("distance");
distance.add(distance_hold);
temp.put("distance", distance_hold);
int[] images = new int[] { R.drawable.local_eat,R.drawable.local_eat,
R.drawable.local_drink, R.drawable.local_shop,
R.drawable.local_do, R.drawable.local_chance,
R.drawable.local_all };
String image = row.getString("promo_type");
temp.put("image", Integer.toString(images[Integer.valueOf(image)]));
String description = row.getString("name");
name.add(description);
temp.put("content", description);
x.add(temp);
}
}
} catch (Exception e) {
// Oops
} finally {
try{if(inputStream != null)inputStream.close();}catch(Exception squish){}
}
}
}
in on post execution add this line. in the end.
x.add(temp);
adapter.notifyDataSetChanged();
