ProgressDialog and TabGroup

I've created a ProgressDialog to show when the user click on a button.

My activity by the way is inside a Tabgroup

Here is my code on ProgressDialog

final ProgressDialog myPd_ring=ProgressDialog.show(MainActivity.this, "Please wait", "Loading please wait..", true);
        myPd_ring.setCancelable(false);
        new Thread(new Runnable() {  
              public void run() {
                    // TODO Auto-generated method stub
                    try 
                    { 
                         //Some data binding here....
                    }catch(Exception e){

                    } 
                    myPd_ring.dismiss();
                    Intent edit = new Intent(getDialogContext(), MerchantActivity.class);
                    TabGroupActivity parentsActivity = (TabGroupActivity)getParent();
                    parentsActivity.startChildActivity("MerchantActivity", edit);
              }
        }).start();

Now everything works fine until when I use the intent. I am getting an error

Here is my LogCat:

Why Am I getting that error? As far as I am concerned I call the parent. Please Help??

Nevermind, I found the answer I was looking for. I just add and it works like charm

                runOnUiThread(new Runnable() {
                              public void run() {
                               // Toast.makeText(activity, "Hello", Toast.LENGTH_SHORT).show();
                                Intent edit = new Intent(getParent(), MerchantActivity.class);
                                TabGroupActivity parentsActivity = (TabGroupActivity)getParent();
                                parentsActivity.startChildActivity("MerchantActivity", edit);
                              }
                            });

Try to run the parentsActivity.startChildActivity("MerchantActivity", edit); on the main UI thread. Something like this:

runOnUiThread(new Runnable() {
    public void run() {
        parentsActivity.startChildActivity("MerchantActivity", edit);
    }
});

BTW, you will have to declare TabGroupActivity parentsActivity and Intent edit as final for this.
