Summary
We have learned about the Android lifecycle and how the operating system calls set methods at set times.
We have also seen that it is not only us that can call our code. The operating system can also call the code contained within the methods we have overridden. By adding the appropriate code into the various overridden lifecycle methods, we can be sure that the right code will be executed at the right time.
What we need to do now is learn how to write some more Java code. In the next chapter, we'll start to focus on Java, and because we have such a good grounding already on Android, we will have no problem practicing and using everything we learn.
