SQLite는 (1) 근처 ")": 구문 오류의 SQLiteDatabase 오류 "SQLite는 (1) 근처") "구문 오류"
나는 내가 생각했던 (그리고 아직도 이해하지 않는다) 그 I 필요한 모든 공간 (및 기타)을 넣으십시오
누군가가 나를 도울 수 있습니까? 시간
public class DatabaseHandler extends SQLiteOpenHelper {

에 대한
덕분에 나는 위의 실수 (에서 onCreate 방법) ...
나머지 ...

다시 한 번 감사드립니다! 와 나는 당신의 문제가 여기 CREATE TABLE SQL COMMAND
+ KEY_ID + " INTEGER PRIMARY KEY, " + KEY_REKORDAI + " TEXT," + ") ";// remove semi column after TEXT
올바른 CREATE TABLE SQL COMMAND 아래
String CREATE_REKORDAI_TABLE = "CREATE TABLE " + TABLE_REKORDAI + " ("
+ KEY_ID + " INTEGER PRIMARY KEY, " + KEY_REKORDAI + " TEXT" + ") ";
