I finally got a chance to run the Tipster application on a real Android powered T-Mobile G phone. I realised that you have to slide open the keyboard to enter values, thus changing the view into a 'landscape mode'. When you do that, the results of the tip calculations are not visible as they are towards the bottom half of the screen. So I experimented and found that I needed to allow 'scrolling' of the view. I have updated the the tutorial with the simple enhancements to make the application visible even in landscape mode.
