Answer 1

Your create table query is messing it up. Column name and its type should have a space in between and also comma is missing. Use this

@Override
public void onCreate(SQLiteDatabase db) {
    String CREATE_AttendanceList_TABLE = "CREATE TABLE " + TABLE_AttendanceList + "("
        + KEY_ID + " INTEGER PRIMARY KEY,"
        + KEY_reg_no + " TEXT,"
        + KEY_firstname + " TEXT,"
        + KEY_lastname + " TEXT," 
        + KEY_surname +  " TEXT"  + ")"; 
    db.execSQL(CREATE_AttendanceList_TABLE);
}

You will have to uninstall the app first then run the updated code.
