Summary

In this chapter, we gained an understanding of how Room is an essential Jetpack library because it allows us to offer offline capabilities to our applications.

First, we explored the core elements of Room to see how a private database is set up. Second, we implemented Room inside our Restaurants application and explored how to save and retrieve cached content from the local database.

Afterward, we discovered what partial updates are and how to implement them to preserve a user's selections within the app.

Toward the end of the chapter, we understood why having a single source of truth for the application's content is beneficial and how that helps us in edge cases such as a system-initiated process death.

In the next chapter, we're going to dive deeper into various ways of defining the architecture of our applications by exploring architectural presentation patterns.
