        ViewUtils.listViewScrollToBottom(listView, true);
       
        IntentUtils.openPlayStoreAppPage(this);

        DialogUtils.showOkDialog(this, dialogTitle, dialogMessage, new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialogInterface, int i) {
