ProgressDialog giving error, while I am using in onCreate() of activity that is in activity group

My code is as following .

public void onCreate(Bundle savedInstanceState) {
    ................
    ................
    showDialog(CONTACT_DIALOG_ID);
            Thread t = new Thread() {
                public void run(){
                    try{

                        sleep(50000);
                    } catch(Exception e) {
                        Log.e("TAG","Exception caught in thread:" + e.toString());
                        //e.printStackTrace();
                    } finally {
                        try{
                            dismissDialog(CONTACT_DIALOG_ID);
                        } catch (IllegalArgumentException e) {
                            Log.w("TAG","Dialog does not exist");
                        }
                    }
                    //finish();  
                }
            };
            t.start();
    ................
    ................
}

and dialog is as ..

 @Override
    protected Dialog onCreateDialog(int id) {
        Dialog dialog = null;
        switch (id) {
        case CONTACT_DIALOG_ID:
            dialog = new ProgressDialog(this);
            ((ProgressDialog) dialog).setMessage("Loading, please wait...");
            break;
        }
        return dialog;
    }

Dialog is not displaying and I am getting errors as below

What is problem in my code?

Your problem is that you try to modify the ui from non the ui-thread. Use handlers for such things. Here is a good example.

Or you can also try like below

replace dismissDialog(CONTACT_DIALOG_ID); with below code

   runOnUiThread(new Runnable()
    {            
        @Override
        public void run()
        {
            dismissDialog(CONTACT_DIALOG_ID);
        }
    });
