Progress dialog problem in Android

Question

I want to create a simple ProgressDialog in my Activity. I created it like this:

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.channellist);

    final Context c=this;

    t1=(TextView) findViewById(R.id.channellistStatus);

    listView=(ListView) findViewById(R.id.channellist);

    rc=RCManager.getInstance();

    chlistAdapter = new ChannelListAdapter(this,R.layout.channellist_row_lyt,clist);

    listView.setAdapter(chlistAdapter);

    t1.setText("No Channel List Found...");

    progDailog=ProgressDialog.show(this,"HI", "Loading");

    new Thread(new Runnable() {

        @Override
        public void run() {
            try 
            {
                Thread.sleep(3000);
            } 
            catch (InterruptedException e) 
            {
                e.printStackTrace();
            }   
            updateChannelList();
        }
    }).start();

But it is resulting in the following Exception ie WindowManager BadToken Exception. I don't know why it is. Please can anyone help me to solve this?

try putting it in onStart() instead. the application window is not yet created in onCreate. — jkhouw1, May 23 '11 at 11:40

I think you are using a `TabActivity` here as a parent class. – Tanmay Mandal May 23 '11 at 11:50

You can't show the dialog before the activity became visible to the user. Call the showing in onResume() or in some button onClickListener.

If you create a new Thread and set it to sleep for some time, only the new Thread sleeps. That has no effect on the UI-Thread where you'r Activity is created! Also, this isn't a good way of doing this anyways.

Also, you can't show the Dialog before your Activity became visible. Try it in the onStart-method.
