How to detect full screen gesture mode in android 10

Question

In Android 10, 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...

I already read it. But can't find any good solution. We can calculate using system bars, but it is not suitable for all devices & apps, since it is non-standard! — Jaya Prakash, Jun 24 '19 at 15:10
Do you mean "fully gestural navigation" by "full screen gestures"? — Charles Annic, Jun 29 '19 at 07:36
@Jaya Prakash Almost 2 year later, were you able to find a solution? — A_Jayke, Jun 13 '21 at 08:54
@A_Jayke Not yet. I still can't believe they didn't include any API for this. :/ — Jaya Prakash, Jun 14 '21 at 10:11

You can use below code to check gesture or navigation mode

    public static int isEdgeToEdgeEnabled(Context context) {
        Resources resources = context.getResources();
        int resourceId = resources.getIdentifier("config_navBarInteractionMode", "integer", "android");
        if (resourceId > 0) {
            return resources.getInteger(resourceId);
        }
        return 0;
    }

The value that returned by isEdgeToEdgeEnabled function will follow below:

0 : Navigation is displaying with 3 buttons
1 : Navigation is displaying with 2 button(Android P navigation mode)
2 : Full screen gesture(Gesture on android Q)

Is using resource identifier reliable? I read that they vary depends on device & may change over time... – Jaya Prakash Mar 18 '20 at 11:59
I found the resource identifier on android Q source code of google. so I think that OEMs will use same id for full screen gesture. – Trung Đoan Mar 19 '20 at 11:36

Important! You need to surround `resources.getInteger()` with try/catch to handle Resources.NotFoundException, otherwise this code will crash on various Xiaomi and Samsung devices. Also this code didn't work on Huawei devices. – Dmide Apr 06 '21 at 10:56
In my case (S21 Ultra, Android 11) config_navBarInteractionMode = 17694897, so this method is not very reliable – Dr. Failov Apr 29 '21 at 17:03

I found this article really useful in explaining what WindowInsets are and how to use them.

Basically I check if the left gesture inset is greater than 0, and if it is then the system is using gesture type navigation. Left and right gesture insets have to be greater than 0 in gesture type navigation because you swipe from the right or left to go back.

int gestureLeft = 0;

if (Build.VERSION.SDK_INT >= 29) {
    gestureLeft = this.getWindow().getDecorView().getRootWindowInsets().getSystemGestureInsets().left;
}

if (gestureLeft == 0) {
    // Doesn't use gesture type navigation
} else {
    // Uses gesture type navigation
}

Obviously, the window has to be rendered for this to work. You can add it inside an OnApplyWindowInsetsListener if you want this to run as soon as the window is rendered.

Note: I tried using getSystemGestureInsets().bottom, but it returned a non-zero value even when I wasn't using gesture type navigation.

Did you tried after hiding the bottom-gesture-indicator bar? — Jaya Prakash, Mar 17 '22 at 04:33
@JayaPrakash No I don't hide that bar, but it should still work. — Sujit, Mar 17 '22 at 16:40

According to docs, there is a hasInsets() method that returns true if the WindowInsets has any nonzero insets.
https://developer.android.com/reference/android/view/WindowInsets#hasInsets()

We can use it this way

view.rootWindowInsets.hasInsets()

Hope this helps!

It returns true, even in gesture mode! – Jaya Prakash Jul 02 '20 at 11:01
It should return true for gestures mode. False otherwise. Does it behave accordingly? – Rami Jemli Jul 03 '20 at 09:38

It returns true for both gesture mode and non-gesture mode. – X09 Feb 10 '21 at 16:47
