When you first opened this book, the last page probably seemed like a long way off. But it wasn't too tough, I hope.
The point is you are here now, and hopefully, you've built a few of the example apps and learned a decent amount of Java and Android along the way.
The motive behind this chapter is to congratulate you on your fine achievement. You have a working Android development environment and know your way around it. Also, you have a firm grasp of the Java programming language and have seen or developed around 40 apps.
It is worth pointing out, however, that this short chapter probably shouldn't be the end of your journey. With this in mind, let's take a look at what you can do next that might benefit you.
