How to update ProgressBar with respect to downloaded data while downloading text data from web using Asynctask in android

Using dynamically created progress bar or referencing it from an id, are both fine.
Using a reference from XML allows you to have more control on the progress bars appearance, as you would have designed it sepcifically for your need (like appearance, where it has to appear, etc..). But if that is not the case, you can use a dynamically created one as in your current code as well.

There is a lot of ways. One is to define ProgressDiaolog as a field in your AsyncTask, then add it to your onPreExecuted():
pDialog = new ProgressDialog(this);
pDialog.setMessage("some downloading massage");
pDialog.setIndeterminate(false);
pDialog.setMax(100); //you can adjust this
pDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
pDialog.setCancelable(false);
pDialog.show();
Then you can update the progress by override updateProgress() in your AsyncTask and call pDialog.setProgress();

AgAppHelperMethods isn't really an Activity. You've derived this class from Activity, but then you've created Singleton management methods (getInstance()) and you are instantiating it yourself. This is bad. Don't do this.
Normally Android controls the instantiation of activities. You don't ever create one yourself (with new).
It looks to me like AgAppHelperMethods just needs to be a regular Java class. It doesn't need to inherit from anything. Remove also the lifecycle methods like onCreate().
Now you will have a problem with the toast, because you need a context for that and AgAppHelperMethods isn't a Context. To solve that you can add Context as a parameter to AgAppXMLParser() like this:
public String[][] AgAppXMLParser(Context context, String parUrl) {
...
// Now you can use "context" to create your toast.
}
When you call AgAppXMLParser() from AgAppMenu just pass "this" as the context parameter.
