The Android Room persistence library is bundled with the Android Architecture Components and acts as an abstract layer above the lower level SQLite database. The library is designed to make it easier to work with databases while conforming to the Android architecture guidelines. This chapter has introduced the different elements that interact to build Room-based database storage into Android app projects including entities, repositories, data access objects, annotations and Room Database instances.
With the basics of SQLite and the Room architecture component covered, the next step is to create an example app that puts this theory into practice. Since the user interface for the example application will require a forms based layout, the next chapter, entitled “An Android TableLayout and TableRow Tutorial”, will detour slightly from the core topic by introducing the basics of the TableLayout and TableRow views.
