SmartGWT mobile skin + size-adjusting

Hey everybody.

So I have some questions concerning the smartgwt using the mobile skin.
I have created a "webpage" and I wanted also to create a app of it.
I set all the components with percentage(setSize("100%","100%) values and so it should work., but it doesn't.
The width of the app is much bigger than the space (so I have to scroll) and the height is much smaller. So the whole app is very little, it's just using the half of the height.

I tried to get width and height of the browser via com.google.gwt.user.client.Window.getClientHeight()/Width(), but these values are also to big/small.

So what can I do to adjust the app to the phones?
