Ошибка базы данных на устройствах Samsung

Question

У меня проблемы с устройствами Samsung. В моем приложении каждый раз, когда я загружаю новую версию на рынок, я хочу заменить базу данных ... но прежде, чем попытаюсь сохранить некоторые данные. Код отлично работает на ADV и на многих устройствах, за исключением таких устройств, как Samsung Galaxy (S series, tab).

Я уже пробовал сделать это .getReadableDatabase() для этого.getWritableDatabase(), но ничего не меняется.

Я также проверил эту аналогичную должность Failed to create SQLite DB in my Samsung y duos device in Android?

Кто-то может мне помочь? Ниже приводится основной код и моя попытка

... 
public void createDataBase() throws IOException{  
    boolean dbExist = checkDataBase(); 
    SQLiteDatabase db = null; 
    if(dbExist){ 

    }else{ 
     db = this.getReadableDatabase(); 
     db.close(); 
     try { 
      copyDataBase(); 
      Log.e(TAG, "createDatabase database created"); 
     } catch (IOException e) { 
      throw new Error("Erro ao copiar banco"); 
     } 
    } 
} 
/* 
Both file or a database check works 
*/ 
private boolean checkDataBase(){ 

    File checkDB = new File (Bd_path + Bd_name); 
    return checkDB.exists(); 

    /*SQLiteDatabase checkDB = null; 
    try { 
     String myPath = Bd_path + Bd_name; 
     checkDB = SQLiteDatabase.openDatabase(myPath, null, 
       SQLiteDatabase.OPEN_READONLY); 
    } catch (SQLiteException e) { 
     e.printStackTrace(); 
    } 

    if (checkDB != null) { 
     checkDB.close(); 
    } 
    return checkDB != null ? true : false;*/ 
} 
... 

Первая попытка - работает отлично, за исключением на устройствах Samsung

public void createDataBase() throws IOException{  
    boolean dbExist = checkDataBase(); 
    SQLiteDatabase db = null; 
    if(dbExist){ 
     try { 
      openDataBase(); 
      Cursor resul = bancoDados.rawQuery("Select ativo from configuracao", null); 
      resul.moveToFirst(); 
      if (Integer.valueOf(resul.getString(resul.getColumnIndex("ativo"))) <= 1) { 
       copyDataBase(); 
       Log.v("Data", "updated"); 
       bancoDados.execSQL("UPDATE configuracao SET ativo = '2'"); 
      } 
      resul.close(); 
      bancoDados.close(); 
     }catch (Exception e) { 
      e.printStackTrace(); 
     } 
... 

Вторая попытка - работает отлично, за исключением на устройствах Samsung

public void createDataBase() throws IOException{  
    boolean dbExist = checkDataBase(); 
    SQLiteDatabase db = null; 
    if(dbExist){ 
     try { 
      db = this.getReadableDatabase(); 
      Cursor resul = db.rawQuery("Select ativo from configuracao", null); 
      resul.moveToFirst(); 
      if (Integer.valueOf(resul.getString(resul.getColumnIndex("ativo"))) <= 1) { 
       copyDataBase(); 
       Log.v("Data", "updated"); 
       db.execSQL("UPDATE configuracao SET ativo = '2'"); 
      } 
      resul.close(); 
      db.close(); 
     }catch (Exception e) { 
      e.printStackTrace(); 
     } 
...
