In this chapter, we built on the work of the previous chapter and explored how more sophisticated layouts can be easily constructed using the coordinator layout and its associated library, which does a great deal of the work for us such as automating collapsing toolbars and preventing overlapping widgets.
We concluded the chapter by exploring another invaluable design library, the percent library, which can solve a multitude of design problem when developing for very different screen sizes and shapes.
The next chapter will expand on this one by exploring more dynamic elements for interface development, such as screen rotation, developing for wearables, and reading sensors.
