Answer 1

처럼은 "_"를 지우고 TABLE 후 space을 넣어,이 같은 AUTOINCREMENT에 AUTOINCREMAENT을 변경해야합니다 :

public static String TABLE_CERATE_SQL = "CREATE TABLE "+TABLE_NAME+" ("+"" + 
              ""+TABLE_KEY_ID+" INTEGER PRIMARY KEY AUTOINCREMENT,"+ 
              ""+TABLE_KEY_FNAME+" text(20), "+ 
              ""+TABLE_KEY_LNAME+" text(30), "+ 
              ""+TABLE_KEY_NICKNAME+" text(20)"+ 
             ")"; 

Answer 2

테이블을 만들 때 구문 오류가 있습니다. 그것은, 당신의 생성 테이블 문장의 Syntax error 있다고 생각이

public static String TABLE_CERATE_SQL = "CREATE TABLE IF NOT EXISTS "+TABLE_NAME+"("+"" + 
              ""+TABLE_KEY_ID+" INTEGER PRIMARY KEY AUTOINCREMAENT,"+ 
              ""+TABLE_KEY_FNAME+" text(20), "+ 
              ""+TABLE_KEY_LNAME+" text(30), "+ 
              ""+TABLE_KEY_NICKNAME+" text(20)"+ 
             ")";
