Issues while using AsyncTask in Android Studion for Two URLs

I have two URLs to fetch JSON Data.
String HttpJSonURL = "https:/.......quiz.php"
String HttpJsonCatQuizURL="https://.....catquiz.php"
Now I am calling the following methods
SaveButtonInSQLite.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
SQLiteDataBaseBuild();
SQLiteTableQuizBuild();
SQLiteTableCatQuizBuild();
DeletePreviousData();
new StoreJSonDataInQuiz(MainActivity.this).execute();
new StoreJSonDataInCatQuiz(MainActivity.this).execute();
}
});
And the methods are defined as
private class StoreJSonDataInQuiz extends AsyncTask<Void, Void, Void> {
public Context context;
String FinalJSonResult;
public StoreJSonDataInQuiz(Context context) {
this.context = context;
}
#Override

progressDialog = new ProgressDialog(MainActivity.this);
progressDialog.setTitle("LOADING Quiz Data");
progressDialog.setMessage("Please Wait");
progressDialog.show();
}
#Override

HttpServiceClass httpServiceClass = new HttpServiceClass(HttpJSonURL);
try {
httpServiceClass.ExecutePostRequest();
if (httpServiceClass.getResponseCode() == 200) {
FinalJSonResult = httpServiceClass.getResponse();
if (FinalJSonResult != null) {

try {

}
}
When I write
new StoreJSonDataInQuiz(MainActivity.this).execute();
OR
new StoreJSonDataInCatQuiz(MainActivity.this).execute();
individually, it fetches data correctly.
But when both lines are executed in sequence then its not doing the job and JSON data not fetched from the 2nd URL.
Please help

Showing ProgressBar on parsing and downloading json result

In my App I am hitting a service which can have no result to n number of results(basically some barcodes). As of now I am using default circular progressbar when json is parsed and result is being saved in local DB(using sqlite). But if the json has large number of data it sometimes takes 30-45 min to parse and simultaneously saving that data in DB, which makes the interface unresponsive for that period of time and that makes user think the app has broken/hanged. For this problem I want to show a progressbar with the percentage stating how much data is parsed and saved so that user get to know the App is still working and not dead. I took help from this link but couldn't find how to achieve. Here's my Asynctask,

Add Update and Delete Item from Listview on Server Response Dynamically

Hi I don't know asking proper question or not but i want to develop Like Comment on Facebook post, Update comment and Delete Comment.
When i will add comment it will send request to server and it will give response with new values to fill in listadapter and that change may appear on my listview after click on enter or add button, and on delete it will send request to server and in response fill my listAdapter. and change may appear on my listview without refreshing listview. how can i perform this operation .

You might have solved this already but I was working on a different app in Java and came across something similar. Mine was a bit simpler because I am using a local database but ~same thing. In your CommmentActivity's onCreate method pull out the commentAdapter declaration and the CommentList.setOnScrollListener and put them in their own method. Then call your newly defined commentAdapter method in onCreate and after you parse through the response.
Something like this
public void myAdaperMethod(Context context, List<CommentListInfo> list_CommentInfo){
commentAdapter = new ListCommentAdapter(this, list_CommentInfo);
CommentList.setAdapter(commentAdapter);
CommentList.setOnScrollListener(new OnScrollListener(){...}
}
onCreate{
myAdapterMethod(...);
}
post{...}
get{myAdapterMethod(...);}
Hope that helps.

You just need to re-bind your control after the listadapter has the new dataset.
CommentList.DataBind();

android - autocomplete text view is not updating

I try to update the autocomplete textview data from the web service based text typed in the textbox. It's working fine but i put the progressbar at the time of web service call because it will take some time in this case autocomplete text view is not showing the drop down menu. I guess autocomplete textview is dissmissed at the time of progressbar dissmissed. How should we put the progress bar in this case.
Code
class GetFundNames extends AsyncTask {
ProgressDialog progress = new ProgressDialog(BasicAutoText.this);
