What we have learned?

We have learned a lot concerning building a well-ordered and organized application that is reusable and flexible using the MVVM architecture. But apart from the architecture itself, we have learned a couple of valuable things along the way, which are mostly Jetpack components.

Let’s highlight them.

• Pagination: In this lesson, we saw how pagination helps load a large dataset by dividing it into smaller chunks, thus making a better use of system resources, including the bandwidth.

• Room: We harnessed the power of the Room library for SQLite mapping by using annotations to write fewer lines of code to persist data locally for offline view, thanks to its easy integration with LiveData to return queries directly.
