Google just recently released the second Android “O” developer preview during Google I/O. Our friends from DeveloperTown are sharing this Android O UI kit. There are twenty five hand crafted vector Android O screens for you to work with. This includes the new Android O style notification screens and settings as well as email, music player, calendar, Hangouts, camera, video, etc. There are more than enough pixels packed in here to get you started on the next killer Android O app!
