I hope you have enjoyed this book! This was a great journey! We began from nothing and started with learning the basics. Then, we continued toward the medium, difficult, and advanced topics about Android. This chapter allowed us the final word on the story about Android we wanted to tell you. We did a huge amount of work! We developed the application and went through the whole process of deployment, step by step.
What is next? Well, the next thing you should do is think about an application you want to build and start making it from scratch. Take your time. Don't rush yourself! During the development, you will discover many things we did not mention. Android is tremendously big! It can take years to know the entire framework. Many developers don't know every part of it. You will not be the only one. Continue your progress and do as much code as you can. It will improve your skills and make all that you learned routine to you. Do not hesitate! Get into the action! Good luck!
