@mikescamell Considerations • No GUI (in progress) • Doesn’t work
with RecyclerViews (coming soon) • It’s in alpha! • Performance? • Elevation shadow tweaking is only 28+ • Difficult to have multiple transitions using same target

@mikescamell Considerations • No GUI (in progress) • Doesn’t work
with RecyclerViews (coming soon) • It’s in alpha! • Performance? • Elevation shadow tweaking is only 28+ • Difficult to have multiple transitions using same target

@mikescamell Summary • Start out simple • Use an empty
project • Read the blog posts & ask questions! #motionlayout • Take advantage of Apply Changes • HAVE FUN!
