SQLiteOpenHelper is a class from the Android SDK which can be used for easier handling of a SQLiteDatabase.

Using the SQLiteOpenHelper only requires implementing its two abstract methods(other methods for different events can be implemented if the user chooses) onCreate(used for initializing the database) and onUpgrade(used when the database is being changed). The Android system will call this methods according to the state of the database( not created/created/upgrading) and in return, it will offer the user a valid SQLiteDatabase reference with the methods getWritableDatabase() and/or getReadableDatabase(). More information can be found in the documentation for the SQLiteOpenHelper class.
