未能在Android應用程序中打開數據庫

在我的應用我試圖獲取從數據庫中的一些數據，我顯示一個列表它。當我在我的摩托羅拉（2.1）和三星Ace（2.3）中運行應用程序時，我的一些模擬器工作正常。未能在Android應用程序中打開數據庫

但是，當我在三星Galaxy Tab，P7500（3.1）運行時，它顯示了以下錯誤

以下是我的DB類文件

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); 
    } 
}

爲什麼會發生這樣的事情？任何一個可以解釋我這....我在這浪費了3天....

嘗試閱讀有關鎖定SQLite數據庫一點。 http://stackoverflow.com/questions/151026/how-do-i-unlock-a-sqlite-database – zmbq

你試試這個代碼

try { 
     db = this.openOrCreateDatabase("chaek.db", MODE_PRIVATE, null); 
     db.close(); 
     openDatabase(); 
     createTable(); 
    } catch (SQLException se) { 
     Toast.makeText(this, se.getMessage(), 1).show(); 
    } 
private void openDatabase() { 
    try { 
db = SQLiteDatabase.openDatabase("/data/data/com.pack.store/databases/chaek.db", 
       null, SQLiteDatabase.CREATE_IF_NECESSARY); 
     //Toast.makeText(this, "DB was opened!", 1).show(); 
    } catch (SQLiteException e) { 
     Toast.makeText(this, e.getMessage(), 1).show(); 
    } 
}// createDatabase

SQLiteDatabase分貝= SQLiteDatabase.openOrCreateDatabase（F，NULL）; //創建數據庫實例 BaseDAO baseDAO =新BaseDAO（續）; baseDAO.onCreate（db）; //baseDAO.onUpgrade（db，baseDAO.getConnectionSource（），OLD_DB_VERSION，DB_VERSION）; //baseDAO.close();//注意要先關掉 db.close（）; //哦，上帝！ –

未能在Android應用程序中打開數據庫
