Abstract:
Periscope is a live streaming video app that makes watching broadcasts a truly interactive experience. Viewers can participate in a live broadcast by sending hearts and chats to the broadcaster. This talk will provide insight into how the Android team built this core user experience. You’ll learn what gives hearts their light, airy feel, how they flutter on the screen, and how chats animate on and off the screen. We’ll describe the why, what, and how behind them, and walk through actual code that powers these custom views and animations.
