데이터베이스를 만들 때 SQLiteException - "android"근처의 SQLiteException

Question

데이터베이스 테이블을 만들려고하는 서비스 (아래에 있음)가 있습니다. PlayerTable에서 onCreate() 내의 SQL이 실행될 때 이해가 안되는 예외가 발생합니다. 모든 코드는 아래에 나열되어 있습니다. 기본적으로 서비스는 시작되고 SQLiteDatabase 객체를 가져오고 CodyBuddyOpenHelper에서 onCreate()를 호출하여 PlayerTable에서 onCreate()를 호출합니다. SQL이 실행될 때 예외가 발생합니다. 어떤 도움을 주시면 감사하겠습니다.

Answer 1

으로는 귀도 지적, 당신은

db.execSQL(db.toString()); 

에 변경해야합니다 : 그것은의 문자열 해석을 보내는

db.execSQL(sb.toString()); 

당신의 db 개체를 SQL 문으로 사용합니다.
