ActiveAndroid

ActiveAndroid is an active record style ORM (object relational mapper). What does that mean exactly? Well, ActiveAndroid allows you to save and retrieve SQLite database records without ever writing a single SQL statement. Each database record is wrapped neatly into a class with methods like save() and delete().

ActiveAndroid does so much more than this though. Accessing the database is a hassle, to say the least, in Android. ActiveAndroid takes care of all the setup and messy stuff, and all with just a few simple steps of configuration.
