Immersive Mode

[tldharold]

Is your feature request related to a problem? Please describe.
I have a Pixel phone and I really hate the 'Navigation Hint' pill at the bottom of the screen. It takes up so much screen real estate and looks ugly. Only way I have found to get out of this is if apps utilize Immersive Mode in some way to hide additional UI.

Describe the solution you'd like
An option to enable Immersive Mode or any other way to hide system UI elements to be able to render pages in true full screen.

Describe alternatives you've considered
Have been using https://github.com/nktnet1/webview-kiosk which has this feature, but it runs so much slower that I am opting to use Fulguris and just deal with the pill.

You can't remove that navbar on Pixel?
On Magic OS they let you hide it.
On Samsung you can also still hide it even though it's a bit twisted now if I recall well.

Hey @tldharold,

Are you able to open a discussion on webview-kiosk about the slowness/performance issue detailing your device model which websites you're experiencing the issue on?

As for potential alternatives, you could try:

Finally, if anyone wants to open a pull request here, the relevant documentation is:

• https://developer.android.com/develop/ui/views/layout/immersive

Sample kotlin code from the link above:

// https://developer.android.com/develop/ui/views/layout/immersive
override fun onCreate(savedInstanceState: Bundle?) {
    ...

    val windowInsetsController =
        WindowCompat.getInsetsController(window, window.decorView)
    // Configure the behavior of the hidden system bars.
    windowInsetsController.systemBarsBehavior =
        WindowInsetsControllerCompat.BEHAVIOR_SHOW_TRANSIENT_BARS_BY_SWIPE

    // Add a listener to update the behavior of the toggle fullscreen button when
    // the system bars are hidden or revealed.
    ViewCompat.setOnApplyWindowInsetsListener(window.decorView) { view, windowInsets ->
        // You can hide the caption bar even when the other system bars are visible.
        // To account for this, explicitly check the visibility of navigationBars()
        // and statusBars() rather than checking the visibility of systemBars().
        if (windowInsets.isVisible(WindowInsetsCompat.Type.navigationBars())
            || windowInsets.isVisible(WindowInsetsCompat.Type.statusBars())) {
            binding.toggleFullscreenButton.setOnClickListener {
                // Hide both the status bar and the navigation bar.
                windowInsetsController.hide(WindowInsetsCompat.Type.systemBars())
            }
        } else {
            binding.toggleFullscreenButton.setOnClickListener {
                // Show both the status bar and the navigation bar.
                windowInsetsController.show(WindowInsetsCompat.Type.systemBars())
            }
        }
        ViewCompat.onApplyWindowInsets(view, windowInsets)
    }
}

I had been using a Samsung previously, and hadn't even considered that it would be an issue when I switched to Pixel. At least as far as I can see there is no way to remove it using stock os/no root. There's a feature request on google's issue tracker that's been open for years about it.

I suppose I could, though the specific page I'm testing is a web app I've been developing for myself that isn't published anywhere. It runs decently in standard chrome, seems to lag in webview-kiosk but runs buttery smooth in fulguris
