Resize Stack Sent Everytime a Stack Opens?

[Brian Milby]

It will take a bit to respond to the rest, but I am not surprised to see a resizeStack on open if the app was built at a size different than the screen size of the device.

On an Amazon Fire the screen/stack delta is the header bar at the top of the screen.  What is strange to me is that the buttons at the bottom of the screen are not included in the screen size so the portrait and landscape dimensions are not reversed as on iOS.  I would imagine if the device had hardware buttons then it would match what I see on iOS.  One difference with Android (at least the version on the Fire) is that you can’t draw behind the header like on iOS.

Thanks,
Brian

I have a browser and a footer that I want to keep occupy the whole screen on any device/screenrect (the "notch" is a nuisance, be leaving that for later nuances....) and changes easily from portrait to landscape layout and back again (with crashing Andriod...) Using the least amount of code as possible.
