In a Google I/O presentation titled “Structure in Android App Design,” Google might have given us a sneak peak at what’s to come for the Gmail Android app. Much of the talk focused on the new navigation drawer that is already present in the latest Google app updates including Earth and Shopper for Android. One slide, as pointed out by AndroidPolice, appears to show off a redesigned Gmail app equipped with the sliding drawer for navigating inboxes (similar to Gmail on iOS) and a number of other tweaks including the removal of the navigation buttons along the bottom of the app. We’ll have to wait and find out for sure if this was simply a mock up for the presentation or the next redesign of the official Gmail app for Android.
