Android fullscreen-immersive

Hi, first post here!

I can’t setup sdl2 on android so it handles correctly fullscreen-immersive.
I can start the app in immersive mode but once the nav bar is shown I can’t hide it. Except by “resuming” the app. Because the events are “eaten” at another level.

I do setup immersive-fullscreen by adding this to my (own extended) Activity class

    public void onWindowFocusChanged(boolean hasFocus) {
        if (hasFocus) {

    private void hideSystemUI() {
        // Enables regular immersive mode.
        // For "lean back" mode, remove SYSTEM_UI_FLAG_IMMERSIVE.
        // Or for "sticky immersive," replace it with SYSTEM_UI_FLAG_IMMERSIVE_STICKY
        View decorView = getWindow().getDecorView();
        //View decorView = findViewById(;
                        // Set the content to appear under the system bars so that the
                        // content doesn't resize when the system bars hide and show.
                        | View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                        | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                        | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                        // Hide the nav bar and status bar
                        | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                        | View.SYSTEM_UI_FLAG_FULLSCREEN);

But i wonder now if sdl2 is not featuring it already? That would be great as many games need immersive-fullscreen.
