In this chapter, we have seen the reasoning behind why we might want to build custom views and layouts, but also, that we have to apply common sense. Android provides a great basic framework for creating UIs and not using it would be a mistake. Not every component, button, or widget has to be completely custom developed, but by doing it so in the right spot, we can add an extra feature that might make our application remembered. Also, we've shown some examples of applications that are already in the market and they're using custom views, so we know we are not alone out there! Finally, we've seen how to set up the environment to get ourselves started and we began taking our own first baby steps on custom views.
In the next chapter, we'll keep adding features; we'll see how to calculate the right size of our custom view and learn more about custom rendering.
