In this chapter, we dived headfirst into the various mediums of data storage that the Android application framework puts at our disposal. We took a look at how we can use internal storage and external storage to store data in private and public files. In addition, we learned how to work with cache files with the help of both internal and external storage.
Further into the chapter, we learned about the SQLite RDBMS and explored how we can make use of it in our Android applications. We learned how to utilize Room to retrieve and store data in a SQLite database and then went a step further by exploring how to use content providers to control access to data with a SQLite database as an underlying datastore.
In the next chapter, we will conclude our Android application framework exploration by learning how to secure and deploy an Android application.
