Suggested Answer: BC 🗳️
Incorrect:
A: onCreate() and onUpgrade() are the only two abstract methods of this class.
D: SQLiteOpenHelper handles database creation and version management.
This class makes it easy for ContentProvider implementations to defer opening and upgrading the database until first use, to avoid blocking application startup with long-running database upgrades.
