안드로이드 개발 질문/답변
(글 수 45,052)
SQLiteDatabase mDatabase = SQLiteDatabase.openDatabase(file_path, null, SQLiteDatabase.OPEN_READONLY);
Cursor m_cursor = mDatabase.rawQuery("SELECT * FROM db ", null);
DatabaseHelper mHelper = new DatabaseHelper(this);
Cursor cursor = mHelper.getReadableDatabase().rawQuery("SELECT score FROM ranking", null);db라는 DB 전체를 SQLiteDabase로 불러오고
ranking라는 DB를 DatabaseHelper로 불러왔는데...
둘이 충돌이 났는지... 에러가 나네요...뭘 잘못한거죠?
