Litho is a declarative Android UI framework which allows you to build more performant and efficient UIs than usual. With Litho you can move your layout phase to the background thread, recycle not only list items, but even individual widgets and do more granular UI updates. It's a very powerful tool with lots of features and possible settings. In this talk I'll discuss best practices and tweaks that you can apply in difficult cases to get the maximum performance out of the framework.
