In this chapter, we analyzed the building blocks required to build a maintainable application. We also looked into one of the most common issues that developers come across when using the Android Framework, which is maintaining the states of objects during lifecycle changes.
We started by analyzing ViewModels and how they solve the issue of holding data during orientation changes. We added LiveData to ViewModels to show how the two complement each other and looked at how we can use other data streams with ViewModels and compare those with LiveData.
