How to detect full screen gesture mode in android Q

Question

In Android Q, users can enable full screen gesture mode. I want to detect whether the device in full screen gesture mode or not. I can't find anything in documentation. How to do it programmatically at run time?

Java or kotlin language answer is OK.

Any official API or workaround...

According to docs, you can get area of gesture space using getSystemGestureInsets(): https://developer.android.com/reference/android/view/WindowInsets.html#getSystemGestureInsets()

If it's zero, then it's disabled

    ViewCompat.setOnApplyWindowInsetsListener(view, (v, insets) -> {
        if (insets.getSystemGestureInsets().bottom == 0 
            && insets.getSystemGestureInsets().left == 0
            && insets.getSystemGestureInsets().right == 0) 
        {
            //gestures enabled
        }
        return insets.consumeSystemWindowInsets();
    });

However, I don't have device with Android Q, and I might be wrong

I've found it in this article: https://developer.android.com/preview/features/gesturalnav
