В моем приложении я пытаюсь получить некоторые данные из базы данных, и я показываю их в списке. Когда я запускаю приложение в моем Motorola (2.1) и в Samsung Ace (2.3) и в некоторых из моих эмуляторов, они работают нормально.

Но когда я запускаю в моем Samsung Galaxy Tab-P7500 (3.1), он показывает следующую ошибку

 sqlite3_open_v2("/data/data/com.pack.store/databases/chaek.db", &handle, 6, NULL) failed

Ниже приведен мой файл класса Db

public class ChaekHelper extends SQLiteOpenHelper 
{
    private static final int DATABASE_VERSION = 7;
    private static final String DATABASE_NAME = "chaek.db";
    private List<Map<String, String>> ALL_TABLES = new ArrayList<Map<String, String>>();
    public ChaekHelper(Context context) 
    {
        super(context, DATABASE_NAME, null, DATABASE_VERSION);
        this.onSetCreateQuery(context);
    }

    @Override
    public void onCreate(SQLiteDatabase db) 
    {
        for (int i = 0; i < ALL_TABLES.size(); i++) 
        {
            db.execSQL("CREATE TABLE IF NOT EXISTS " + ALL_TABLES.get(i).get("TABLE_NAME") + " ( "+ ALL_TABLES.get(i).get("FIELD_NAME") + " );");
        }

        // create Index table
        db.execSQL("DROP TABLE IF EXISTS dual;");
        db.execSQL("CREATE TABLE dual (idx INTEGER PRIMARY KEY, rownum TEXT);");
        db.execSQL("CREATE UNIQUE INDEX idx_rownum ON dual (rownum);");

        // create all tables
        db.beginTransaction();
        try 
        {
            for (int i = 1; i < 100; i++) {
                String idxStr = "0" + i;
                if (i > 9)
                    idxStr = idxStr.substring(1);

                db.execSQL("INSERT INTO dual (idx, rownum) VALUES (" + i + ",'" + idxStr + "');");
            }
            db.setTransactionSuccessful();
        }
        catch (Exception e) {
            e.printStackTrace();
        }
        finally {
            db.endTransaction();
        }
    }

    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
        for (int i = 0; i < ALL_TABLES.size(); i++) {
            db.execSQL("DROP TABLE IF EXISTS " + ALL_TABLES.get(i).get("TABLE_NAME") + ";");
        }
        onCreate(db);
    }

    private void onSetCreateQuery(Context context) {
        Map<String, String> params;

        // 1. BOOK
        params = new HashMap<String, String>();
        params.put("TABLE_NAME", context.getResources().getString(R.string.BOOK_TBL_NAME));
        params.put("FIELD_NAME", context.getResources().getString(R.string.BOOK_TBL_FIELDS));
        ALL_TABLES.add(params);

        // 2. TOC
        params = new HashMap<String, String>();
        params.put("TABLE_NAME", context.getResources().getString(R.string.TOC_TBL_NAME));
        params.put("FIELD_NAME", context.getResources().getString(R.string.TOC_TBL_FIELDS));
        ALL_TABLES.add(params);

        // 3. BOOKMARK
        params = new HashMap<String, String>();
        params.put("TABLE_NAME", context.getResources().getString(R.string.BM_TBL_NAME));
        params.put("FIELD_NAME", context.getResources().getString(R.string.BM_TBL_FIELDS));
        ALL_TABLES.add(params);
    }
}

Почему так происходит? Может ли кто-нибудь объяснить мне об этом .... я потратил три дня на это ....
