Screenshot shows new Android P navigation bar; multitasking button replaced by gesture?
The new navigation bar consists of two icons. Gone is the multitasking button that will be replaced by a swipe-up gesture. While the home button remains, it now is a pill or lozenge shaped icon. The back button remains the same, although it will reportedly disappear from view when it cannot be used. For example, you won't see it when viewing your home screen. While Google has not confirmed any of this, the pill-shaped home button does resemble something seen on the render of the Moto Z3 Play that we passed along earlier this year.
We should know for sure about the Android P navigation bar (and any associated gestures) next month at Google I/O. The annual developers conference will be held May 8th to the 10th at the Shoreline Amphitheatre at San Francisco, California. And by the way, it appears that Popsicle is the morning line favorite to be the next dessert used to name the next Android OS build.
