Exploring MotionLayout
summary
MotionLayout is a ConstraintLayout-based system that claims to make animations easier: a worked example replaces CollapsingToolbarLayout using ConstraintSets and a separate MotionScene, explicit support for Keyframes, KeyAttributes and the powerful KeyCycle (wavePeriod/waveShape/waveOffset), plus touch-driven KeyTimeCycle. Tooling includes a Cycle Editor for visualizing cycles. Timeline shows alpha releases since June 2018; examples run at ~55 fps in the emulator and a client project reports stable behavior with no motion-caused crashes.
