Google executive Locheimer speaks up about Android38
He also went on to mention that Android 5.0 is the first build of the operating system that was planned, developed and released all under the leadership of Sundar Pichai. Lollipop includes the new ART Runtime which makes running the UI smoother and more fluid. That includes the animations used with the new Material Design. And the move to 64-bit all combined together to make Android 5.0 a huge release for Google.
And Locheimer also wanted to point out that the reason for introducing Android L at Google I/O this past summer, was to give developers time to make sure that their apps would work on the new build. It was the first time that Google had given an early preview. Some features for Android were re-worked in 5.0. Face Unlock, which first appeared with the Ice Cream Sandwich build of Android, originally required users to align the camera with their face. But to make the process quicker, with Android 5.0 the feature starts looking for your face even before the lighting is set.
Hocheimer has been with Google since 2006. At the time, the Android division consisted of 20 people, and as the executive said, "Things have changed a lot"
