Re: [android-developers] Re: Virtual screen size
No the whole point is the launcher is the one with the virtual screen, so it is the one that sets the values. It is the one that says the range, it is the one that updates the position as you scroll throw its UI. If you don't like what it is doing, you can use a different launcher.
