Now we know how to make our apps audible. Most apps we will build in this book are of the type to which you would probably only add a few beeps or buzzes, but when you design your own apps, you might want to go further, and now you can. We also saw how to use yet another useful widget from the palette: Spinner.
This chapter concludes the Note To Self app, and it is time to move on to more advanced Android programming. As we will see, more advanced does not necessarily mean more complicated; however, we will see quite a few new topics that will be introduced over the rest of the book.
In the next chapter, we will see how we can start to code even more real-world apps using the Fragment class, and how we can keep our ever-growing code organized with design patterns.
