Because it...helps?

http://developer.android.com/reference/android/database/sqlite/SQLiteOpenHelper.html :

A helper class to manage database creation and version management.

I personally find it's really handy and it makes the SQLite DB handling in my application very easy. I was surprised how simple it is to implement DB handling.

I also enjoy the fact that I just use the instance of my helper class and getWriteableDatabase() or getReadableDatabase() depending on what I need and it just works.
