нет такого исключения таблицы

У меня проблема с доступом к базе данных. Самое забавное, что он работал хорошо, но в последнее время он начал показывать SQLiteException «нет такой таблицы». Это происходит не каждый раз, когда я запускаю приложение, время от времени, и я не вижу никакой конкретной настройки, которая вызывает проблему. Однако он всегда связан с одной и той же таблицей form_data в том же классе RunForm. Я проверил в adb, что таблица и база данных существуют. Вот мой CREATEDB класс общественного класса CREATEDB {нет такого исключения таблицы

private static final String DATABASE_NAME = "mydatabase.db"; 
private static final String DB_PATH = "/data/data/com.mypackage/databases/"; 
private static final int DATABASE_VERSION = 2; 

private OpenHelper openHelper; 

private Context context; 
private SQLiteDatabase db; 

public createDB(Context ctx){ 
    try{ 
     this.context = ctx; 

     openHelper = new OpenHelper(context); 

     this.db = openHelper.getWritableDatabase();   
    } 
    catch (IllegalStateException e){ 
     Log.e("ILLEGALstateEXC","CAUGHT"); 
    } 

} 


public SQLiteDatabase openDataBase(){ 

    //Open the database 
    String myPath = DB_PATH + DATABASE_NAME; 
    try{ 
     db = SQLiteDatabase.openDatabase(myPath, null, SQLiteDatabase.CREATE_IF_NECESSARY); 

    }catch(Exception e){ 
     Log.e("Opening database", e.toString()); 
    } 

    return db; 
} 



public boolean checkDataBase(){  
    SQLiteDatabase checkDB = null; 
    try{ 
     String myPath = DB_PATH + DATABASE_NAME; 
     checkDB = SQLiteDatabase.openDatabase(myPath, null, SQLiteDatabase.OPEN_READONLY);   
    }catch(SQLiteException e){ 
     //database does't exist yet. 
     checkDB = null; 
    } 
    if(checkDB != null){ 
     checkDB.close(); 
    } 
    return checkDB != null ? true : false; 
} 


public void close() 
{ 
    openHelper.close(); 
} 


private static class OpenHelper extends SQLiteOpenHelper { 
    OpenHelper(Context context) { 
     super(context, DATABASE_NAME, null, DATABASE_VERSION); 
    } 

    @Override 
    public void onCreate(SQLiteDatabase db) { 
     // TODO Auto-generated method stub 

    } 

    @Override 
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { 
     // TODO Auto-generated method stub 

    } 
}

В дополнение к этому я создал два класса (dataDB и structureDB), которые содержат операции на конкретных таблиц базы данных (включая создание таблиц). Они в основном такие же, поэтому я показываю только один, который выполняет операцию в таблице form_data, что вызывает проблему.

public class dataDB{

private structureDB structure_db;

private String[] TABLE_EXTRAS_FIELDS = {"id", "name", "value", "instance_number", "plot_number"}; 

private String TABLE_VERSION = "form_version"; 
private String[] TABLE_VERSION_FIELDS = {"id", "name"}; 

public dataDB(SQLiteDatabase database){ 
    Log.e("DATA_DB","CONSTRUCTOR");

structureDB structure_db = new structureDB(db); 
dataDB data_db = new dataDB(db); 
Intent i = new Intent(dynamicTabs.this,RunForm.class); 
... 
}

и onCreate of RunForm Деятельность

protected void onCreate(Bundle savedInstanceState) {

createDB database = new createDB(this); 
db = database.openDataBase(); 
structureDB structure_db = new structureDB(db); 
dataDB data_db = new dataDB(db); 
this.structure_db.getFieldLabel(fieldID) 
this.data_db.getItemInstanceValue(fieldID, 0, this.formPlotNo); 
... 
}

Ошибка в последней строке кода при попытке выбрать значение из таблицы form_data. Более ранние запросы с использованием класса structDB работают нормально. LogCat показывает следующее:

Я сделал некоторые изменения и избавиться от IllegalStateException, но проблема все еще существует и журналы выглядят следующим образом (база данных уже успешно прочитаны много раз, но до сих пор form_data таблица вызывает проблемы):

Пожалуйста, сообщите ваши ошибки logcat. – Sam

Добавлен полный логарифм (на всякий случай я включил и другие журналы, кроме ошибок). Также я оставил dAWF, который является тегом моего приложения, чтобы показать последовательность действий и порядок в том, какие действия создаются, если я не описал это четко в вопросе. – krltos

Посмотрите на Finalizing a Cursor that has not been deactivated or closed non-fatal error

Посмотрите на вашего исключения. Это связано с управлением курсором. Попробуйте использовать startManagingCursor.

Теперь я более осторожен в управлении курсором, так что не существует IllegalStateExceptions (см. Последний журнал), но это не решило проблему. – krltos

нет такого исключения таблицы
