Can't dismiss ProgressDialog in Android app

I am a beginner Android programmer. Trying to use AsyncTask and ProgressDialog but encountered a problem -- the ProgressDialog is unable to be dismissed.

The following codes are inside an importExportActivity which extends Activity --

public class ProgressTask extends AsyncTask<Void, Void, Void> {    
    ProgressDialog dialog1 = new ProgressDialog(importExportActivity.this);

    protected void onPreExecute() {
          this.dialog1.show(importExportActivity.this, "",
                                  "Please wait for few seconds...", true);
    }

    @Override
    protected void onPostExecute(final Void success) {
          dialog1.dismiss();
    }

    protected Void doInBackground(final Void ... args) {
               ...... did the main logic ....
          return null;
    }
 }

Done a lot of google search but can't seem to find a solution to this.

Can someone help?

Answering my own question. The following worked:

public class ProgressTask extends AsyncTask<Void, Void, Void> {    
ProgressDialog dialog1; 

protected void onPreExecute() {
      dialog1 = ProgressDialog.show(importExportActivity.this, "",
                              "Please wait for few seconds...", true);
}

@Override
protected void onPostExecute(final Void success) {
      dialog1.dismiss();
}

protected Void doInBackground(final Void ... args) {
           ...... did the main logic ....
      return null;
}

}

I think you are not returning :

 @Override
protected void onPostExecute(final Void success) {
      dialog1.dismiss();
    return;

}

protected void onPreExecute() {
      this.dialog1.show(importExportActivity.this, "",
                              "Please wait for few seconds...", true);
      super.onPreExecute();
}

@Override
protected void onPostExecute(final Void success) {
      dialog1.dismiss();
      super.onPostExecute(RESULT);
}

mine is working this way ...
