You need to add following code to your implementation. You need to pass Activity as a parameter in the AsyncTask constructor :

/** progress dialog to show user that the background task is processing. */
    private ProgressDialog dialog;

    public RetrievePdfView(Activity activity) {
        dialog = new ProgressDialog(activity);
    }

   @Override
   protected void onPreExecute() {
       this.dialog.setMessage("Progress start");
       this.dialog.show();
   }

    @Override
    protected void onPostExecute(final Boolean success) {
       if (dialog.isShowing()) {
           dialog.dismiss();
       }
    }

In order to call this AsyncTask you need call it like this in your Activity :

RetrievePdfView task = new RetrievePdfView(this);
task.execute(inputStreamString);
