For setup designs that use windows, the user may want the window to open in full screen so it is the focused object.
Toby says
the full screen result may require 3 adjustments:
The System UI: Android usually reserves a slim portion at the top of the screen for the status bar. Some users may hide the status bar (Launcher Options > UI & Animations > Hide status bar) and while the bar is hidden, its space remains. See below on how to Overlap system UI
Window Option Edit allows the setting of Full height
Window Resizing can be done manually by dragging the boundary or with the

icon to enter exact height and width as well as x/y coordinates.
Remember to check the contents of the window as well. If the window contains a shape or widget that does not extend to its boundaries or if the widget has margins which prevent it from resting on the window's edge, adjust these.
