Мобильная версияоднако он уже очень устарел, и, скорее всего, он устарел в текущем Android API 35+.
Поэтому я гуглил столько, сколько мог, использовал множество примеров для переписывания новых функций, однако высота statusBar, NavigationBar и выреза всегда возвращает ноль, что явно неправильно.
В следующем примере я закомментировал с помощью «OLD» то, как я использую рабочий код, с помощью «NEW» — что не работает новый код и «ПРИМЕЧАНИЕ» — открытый вопрос. Я даже не знаю, как заменить СТАРЫЙ на НОВЫЙ.

// NOTE: I found no mention if this is even needed when not using setStatusBarcolor() anymore, but will use WindowInsets.Type.statusBars() - my guess its not needed anymore
// OLD: // The Window flag 'FLAG_TRANSLUCENT_NAVIGATION' will allow us to paint the background of the navigation bar ourself
// OLD: // But we will also have to deal with orientation and OEM specifications, as the navigationBar may or may not depend on the orientation of the device

// OLD: window.setNavigationBarColor(Color.TRANSPARENT); // DEPRECATED
// NOTE: Draw proper background behind WindowInsets.Type#navigationBars() instead
// OLD: // Statusbar background is now transparent, but the icons and text are probably white and not really readable, as we have a bright background color
// OLD: // We set/force a light theme for the status bar to make those dark
// OLD: View decor = window.getDecorView();
// OLD: decor.setSystemUiVisibility(decor.getSystemUiVisibility() | View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR); // DEPRECATED
// NOTE: Use WindowInsetsController#APPEARANCE_LIGHT_NAVIGATION_BARS instead. I guess something like:
window.insetsController?.setSystemBarsAppearance(WindowInsetsController.APPEARANCE_LIGHT_STATUS_BARS, WindowInsetsController.APPEARANCE_LIGHT_STATUS_BARS); // for light mode, therefore dark foreground (text/icons)... NOTE: does it works on its own or do I need to set something specific, like addFlags() to make this work?
