Summary
In this chapter, you have covered a lot of the groundwork of how your application interacts with the Android framework, from the Activity lifecycle callbacks to retaining the state in your activities, navigating from one screen to another, and how intents and launch modes make this happen. These are core concepts that you need to understand in order to move on to more advanced topics.
In the next chapter, you will be introduced to fragments and how they fit into the architecture of your application, as well as exploring more of the Android resources framework.
