Feature Request

Motivation Behind Feature

In Android Pie, there is a new way to navigate using gestures instead of buttons to get more screen space, but I couldn't use theses gestures in a Cordova app.

Just adding information relevant to this feature request.

The android documentation for gesture navigation can be found here

I've verified that the gesture navigation triggers backbutton event, there is nothing to do in Cordova's part.

Note that I wasn't able to test gesture navigation on Android 9 as the title said, only on Android 10+, it's not that it didn't work on Android 9, I wasn't able to enable gesture navigation on Android 9 emulators (didn't find the option)

The android docs also does say:

Beginning with Android 10 (API level 29), the Android system supports fully gesture-based navigation.

So gesture navigation in Android 9 might be non-standard or incomplete feature.
