Android P may support gesture navigation and may introduce new sideslip gestures.
the new screenshot posted from the Android Developers blog shows that the next version of Android P will support gesture navigation. While it doesn't rule out the possibility that Google's Android team freaked out bad designs, there's a good chance that Google is thinking about how to lay out gesture navigation.
Does it look a little strange? Observe the navigation bar carefully
the following is the navigation bar for Pixel 2 running Android Oreo (as with the Android P Beta version):
you can see that the multitasking button on the right has been cancelled, while the middle main button has changed into a very strange pill shape. Stephan Hall, editor of foreign media 9to5Google, said that the "recent" button has been removed, and the return button here will also be removed. Foreign media ArsTechnica pointed out that Android P navigation in the application may introduce a new side-slip gesture.
