Remove
if (pDialog.isShowing())
and
use if (pDialog != null)
may this help you

You should remove super.onPostExecute(result); as you have your implementation of onPostExecute(), so you may not want framework to handle it.
Since you have definitely showed the Progress Dialog in onPreExecute(), then you can also omit check for isShowing(), but i will recommend you to keep this check as it causes no harm and adds little more security.

In your onPostExecute() block you are calling super.onPostExecute(result);
#Override
protected void onPostExecute(Void result) {
super.onPostExecute(result);
// Your code
}
However as you are overriding the onPostExecute() there is no need to call super.onPostExecute(result);
If you take a look at the AsyncTask source, you will see that the super class does nothing:
#SuppressWarnings({"UnusedDeclaration"})
protected void onPostExecute(Result result) {
}

AsynTask with Endless Listview Scroll in android

I am creating an application where in i need to have endless scrolling listview. I dnt want to use any library in my application. I have seen some examples on line that help in achieving such listview,but my doubt is how can i have an endless listview when my data are coming from server and are getting parsed in the Asynctask. How can i load 10 items at a time from my asynctask on scroll? I want to know to implement a endless listview on asyntask.
Do i call my asynctask in the onScroll() or not???

Thanks in advance.

ListView already supports OnScrollListener, so you have to override it and check the condition(in onScroll()), whether it is reached to the end of the list or not.If yes, then add a footer(optional) and fire the async task. After reciving the result notify the adapter. You could check solution on this link, it works on the same concept.

here are few examples of what you are looking for:

Handling Activity stack through application programmatically

I have four activities in my application A-->B-->C-->D.
I write a My own class MyActivity which extends Activity class. I write this class to handle activity stack.This class has two methods addActivitiyTostack() and getActivityFromStack()
I used a stack for storing activities.
All other activities are extends this class.
When I moved from one activity to other using intent it added to stack.
And when I moved backword activity gets popped up.
I can correctly add activities to stack, But I have problem in popping the activities.
also I have Logout Button on all activities, OnClick of this button I want to close the application how to implement it? Anybody know how to handle activity stack in Android.
This is my code.
package com.example.iprotect;
import java.util.Enumeration;
import java.util.Stack;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
public class MyActivity extends Activity {
private static Stack<Activity> stack = new Stack<Activity>();
static int top=0;
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
addActivityToStack(this);
}
public static void addActivityToStack(MyActivity myActivity) {
// TODO Auto-generated method stub
stack.push(myActivity);
for (int i =0; i< stack.size() ; i++) {
Activity act=stack.get(i);
Log.i("Element in stack", ""+act);
}
}

Assuming you need this stack solely for the logout function, there are better ways. Use a broadcast instead. Register a BroadcastReceiver in MyActivity.onCreate. The receiver should just call the activity's finish(). Send the broadcast from the button's click listener (btn1? What does that button do? Couldn't guess from the name; better names required ;) ). That's it.
