In my class SettingsActivity code of method where pops up error.

private void fetchDatabaseFromServer() {
        UserOperationsTask getCountriesTask = new UpdateCountries(new DialogProgressFragment() {
            @Override
            public void onComplete(boolean success) {
                dismiss(); // here i get error
                updateDatabaseSize();
                updateFilters();
                MeasureUtils.makeDefaultTemplate(SettingsActivity.this, true);
            }
        });
        getCountriesTask.execute(SettingsActivity.this);
        showProgress();
        updateDataBaseProfile();
    }

My inner class

private class UpdateCountries extends UserOperationsTask {
        final DialogProgressFragment progressDialog;

        UpdateCountries(DialogProgressFragment progressDialog) {
            super(UserOperationsTask.TaskMode.MODE_LOAD_COUNTRIES, null);
            this.progressDialog = progressDialog;
        }

        @Override
        public void onLoadFinished(Bundle resultData) {
            setRegionLabels();
            updateFilters();
            hideProgress();
            String errorMessage = resultData.getString(UserOperationsTask.RESULT_ERROR_STRING);
            if (errorMessage != null) {
                Log.d(TAG, "getCountriesFromServer error: " + errorMessage);
                showMessage(getString(R.string.info_title), getString(R.string.server_request_error));
            } else {
                progressDialog.start(SettingsActivity.this, DialogProgressFragment.DialogMode.MODE_UPDATE);
                progressDialog.setCancelable(false);
                progressDialog.show(getSupportFragmentManager(), DialogProgressFragment.class.getSimpleName());
            }
        }
    }
