There is not a whole lot that you can do to access the text view. AFAIK, everything must be done through the RemoteViews object and its appropriate "set..." functions like you have here : updateViews.setTextViewText(R.id.myTxt,"Helloworld");
You can access some other functions of TextView via functions like setInt(), setDouble(), setFloat()... But I am not positive which ones are accessible in this way.
