- Index
We have covered a lot in this chapter. We have learned about databases and, in particular, the database of Android apps, SQLite. We have practiced the basics of communicating with a database using the SQL language.
We have seen how the Android API helps us use a SQLite database, and have implemented our first working app with a database.
In the next chapter, we will start to build an app from the most popular category on Google Play—a game.
