I reviewed your code and solved your problem.
There are two things need to discuss.
Your API providing the results according to localisation.If we change first two fields results will remain same and web service is fetching only one item with localisation 'oran'. But if we change localisation from 'oran' to 'alger' web service is displaying 4 results.
Here is the problem in your code.You are not concatenating your results properly in your data string. I have updated your code and now your code of AsyncCaller in announces Activity should be like:
Here is the code
private class AsyncCaller extends AsyncTask<Void, Void, Void>
{
ProgressDialog pdLoading = new ProgressDialog(annonces.this);
#Override
protected void onPreExecute() {
super.onPreExecute();
//this method will be running on UI thread
pdLoading.setMessage("/tChargement des annonces en cours ... ");
pdLoading.show();
}
#SuppressLint("NewApi")
#Override
protected Void doInBackground(Void... params) {
try {
URL url = new URL("https://www.waslup.pw/wp-admin/admin-ajax.php?action=do_ajax&fn=get_posts&count=10&key="+skey+"&cat="+scat+"&loc="+sloc);
HttpURLConnection httpuc = (HttpURLConnection) url.openConnection();
InputStream inputstream = httpuc.getInputStream();
BufferedReader bf = new BufferedReader(new InputStreamReader(inputstream));
StringBuilder total = new StringBuilder();
String line;
while ((line = bf.readLine()) != null) {
total.append(line).append('\n');
}
JSONArray JA = null;
JA = new JSONArray(total.toString());
annonces.Items.removeAll(annonces.Items);
for (int i=0 ; i<JA.length();i++){
JSONObject JO =(JSONObject) JA.get(i);
date =""+ JO.get("date");
loc =""+ JO.get("loc");
cat =""+ JO.get("Cat");
vue =""+ JO.get("vue");
titre =""+ JO.get("title");
id =""+ JO.get("Id");
annonces.Items.add(new annonce_item(id,date,loc,cat,vue,titre));
}
} catch (MalformedURLException e) {
} catch (JSONException e) {
Log.d("js_ex:",e.toString());
} catch (IOException e) {
Log.d("io_ex:",e.toString());
}
return null;
}
#Override
protected void onPostExecute(Void result) {
super.onPostExecute(result);
//this method will be running on UI thread
pdLoading.dismiss();
final MyCustomAdapter myadpter = new MyCustomAdapter(Items);
ListView ls = (ListView) findViewById(R.id.listannonce);
ls.setAdapter(myadpter);
ls.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
TextView titre = (TextView) view.findViewById(R.id.titre);

Intent intent = new Intent(getBaseContext(), annonce_details.class);
intent.putExtra("id_from_annonces_activity", id2.getText());
startActivity(intent);
}
});
}
}
In this code i added this part
StringBuilder total = new StringBuilder();
String line;
while ((line = bf.readLine()) != null) {
total.append(line).append('\n');
}
JSONArray JA = null;
JA = new JSONArray(total.toString());

Is my Rss Reader app not working because there are too many parsers (Android Studio)?

I'm a high school student working for a magazine in South Korea known as Teen 10 Magazine. As an aspiring computer science major, I decided to make an RSS reader app for my magazine in order to showcase my skills for college applications (and also to create an app, which has always been my interest). Basically, I want to format my app to be similar to your typical news app (ex. CNN, BBC, etc).
Category Screen
In a DrawerLayout (as seen in the Category Screen), I decided to make a tab for each different category (such as News, Features, Entertainment, etc), including the Home category, which is where the categories the articles are under don't matter. When users click on each different tab, it gives them a list of articles that are categorized under that category. In order to get this data, I'm parsing the data to get the title (which is displayed in the list) and the link (which is set to an Intent so that users can access the article in the Web when it is clicked)
However, while some of the categories do work (Home, Lifestyle, Fashion), the rest of the categories are stuck in the loading screen for almost an infinite amount of time.
Example of loading category
I'm pretty sure that the codes of the categories that work and the categories that don't are the same (for reference, I copied and pasted and adjusted each different category accordingly, which could also be an issue but I'm not sure), and are getting their data from the appropriate sites.
Is it perhaps there are too many parsers (RssParser does the actual parsing and seven different "RssService"s use the parser to parse the data from each different category) for my app to work with? My app does seem to crash once in a while though...
I will post my codes below:

This is my first question, so I tried to be as detailed as possible. If my explanations were unreasonably lengthy, I do apologize. This is also my first time coding something this extensive, so forgive me if I seem to make amateur mistakes...
Thank you in advance for all of your help!!

Log Message
I have no idea how to solve the issue of android.database.CursorIndexOutOfBoundsException: Index 0 requested, with a size of 0.
I have tried adding the following code at the update() in the MessageStore.java:
if (cursor!= null && cursor.moveToFirst())
but yet no avail. Can anyone helps me? Application crashes every time I load it.
Thank you in advance.

Exception is raised in method getRecepientById() of ContactStore. It seems that addrCursor has no records.
Add a check if addrCursor has any records to be safe. In case there's no recepient return null.
Cursor addrCursor = sResolver.query(Uri.parse("content://mms-sms/canonical-address/" + recipientId), null,null, null, null);
if (addrCursor.moveToFirst()) {
String number = addrCursor.getString(0); // we got number here
number = number.replace(" ", "");
number = number.replace("-", "");
Contact c = db.findContactByNumber(number);
return c;
} else {
return null;

navigation drawer not working after asynctask

I am using navigation drawer with asynctask in one of the fragments. As soon as I click the element in navigation drawer to start that fragment, my navigation drawer stops working even after the asynctask is finished. I am able to click on navigation drawer and open it , but whenever I click on some other item in navigation drawer, it just closes without loading that fragment associated with that item in nav drawer.

Once again, nothing fancy here. still cant figure out what is making the navigation drawer to just close and not start the fragment, if it is clicked on item to start another fragment.
Thanks.

I guess it will be the Home.bar covers your fragment? Maybe you should use ProgressBar.show() or ProgressBar.dismiss() to control the visibility of the progressbar
