말 그대로 에뮬레이터에서는 작동이 잘 됩니다. Google API 12 에서 동작 시켰고
핸드폰은 4.0.4입니다.
아래는 에러 내용입니다.

에러 난 코드 부분입니다.
com.crucialsoft.softCalendar.db.CalendarDatabase.getcolumns(CalendarDatabase.java:91) :
public Cursor getcolumns(String[] columns) {
return mdb.query(InterfaceDB.TABLE_NAME, columns, null, null, null,
null, null);
}
com.crucialsoft.softCalendar.CalendarMain.onCreate(CalendarMain.java:111) :
Cursor result = mDb.getcolumns(InterfaceDB.TB_DATA);
Cursor 를 선언한 부분과 불러오는 부분에서 에러가 nullPoint가 난 것 같은데,
저번 주 까지만 해도 잘 되던게 갑자기 왜 이러는지 모르겠습니다.
