SQLiteException when creating database - SQLiteException near "android"

I have a service (listed below) which is trying to create database tables. The am getting an exception I don't understand when the sql within onCreate() in PlayerTable is executed. All the code is listed below. Basically, the service starts up, gets an SQLiteDatabase object, which in turn is calling onCreate() on ClueBuddyOpenHelper which then calls onCreate() in PlayerTable. The exception occurs when the sql executes. Any help would be appreciated.
