ProgressDialog leaked window error only in Portrait mode

Question

I am developing an app which takes a picture and does some long processing. During processing I would like to show the status via a ProgressDialog, hence I extended the AsyncTask class as following

private class ResultTask extends AsyncTask<multiCrop, String, String> {

    @Override
    protected void onPreExecute() {
        super.onPreExecute();
        progressDialog = new ProgressDialog(MainActivity.this);
        progressDialog.setTitle("Analyzing, please wait ...");
        progressDialog.setMessage("Loading..");
        progressDialog.setCancelable(false);
        progressDialog.show();
    }

    @Override
    protected String doInBackground(multiCrop... mcImgV) {
        String result = null;
        //Long processing that uses view multiCrop and occasional publishProgress() calls, returns String result
    }

    @Override
    protected void onProgressUpdate(String... str) {
        // TODO Auto-generated method stub
        super.onProgressUpdate(str);
        progressDialog.setMessage(str[0]);
    }

    @Override
    protected void onPostExecute(String result) {
        super.onPostExecute(result);
        ((TextView)findViewById(R.id.resultText)).append(result);
        progressDialog.dismiss();
    }

}

An instance of ResultTask is created in the onClick handler of one of the buttons in the view as shown below

public void onResultClick(View v){
    ResultTask task = new ResultTask();
    task.execute(babyImageView);
}

When the device is in Landscape the code works without any problem, but if the onResultClick event is triggered in the portrait mode I get an error stating that MainActivity has a LeakedWindow. What am I missing here ?

* Please note that this error occurs even if there is no orientation change

Try this --

    protected void onPostExecute(String result) {
            super.onPostExecute(result);
   progressDialog.dismiss();

   ((TextView)findViewById(R.id.resultText)).append(result);
         }

First thing try to use progress dialog inside the UI thread.

        public class LoginScreen extends FragmentActivity {
        ProgressDialog progressDialog;


        @Override
        protected void onCreate(Bundle arg0) {
            // TODO Auto-generated method stub
            super.onCreate(arg0);
            requestWindowFeature(Window.FEATURE_NO_TITLE);

                setContentView(R.layout.activity_login);
    progressDialog = ProgressDialog.show(
                                                LoginScreen.this, null,
                                                "Logging you in...");
                                        progressDialog.setCancelable(false);
    }
public void progressDialogDismiss() {
        LoginScreen.this.runOnUiThread(new Runnable() {
            @Override
            public void run() {
                if (progressDialog.isShowing())
                    progressDialog.dismiss();
            }
        });
    }
    }

Try to use like this. use it an util class.

Sorry people, apparently the error was in the few lines just before ResultTask instance, I was extracting bitmap from the multiCrop view which was outside the bounds of the view.

Thanks for all your suggestions.
