Android Sqlite singleton db filestream update failed

Question

I have an application uses sqlite db, at first install I check If database folder nor db file exists If not call updateDB function. but some cases for example on galaxy note 10.1 It gaves me error.

on Load ;

    this.dhn = DataHelper.getDataHelper(this);

    File directory = new File(Environment.getDataDirectory() + File.separator + "data" + File.separator + "XXX" + File.separator + "databases");
    if(!directory.exists())
    {
        directory.mkdirs();
        updateDB();
    }

    try {
        androidCheckout = this.dhn.Guid();

        if(this.dhn.getSettings("dbVersion") == null || Integer.parseInt(this.dhn.getSettings("dbVersion")) != Version || !this.dhn.isTableExists("UserInfo"))
        {
            updateDB(); 
        }
    }
    catch (SQLiteException e)
    {               
    try {
            updateDB();
            androidCheckout = this.dhn.Guid();
        }
    catch (SQLiteException e11)
        {   
            ManuelYukle();
        }

    }



  public void updateDB()
    {
      this.dhn.close();

        try {
            InputStream myInput;

                myInput = getAssets().open("XXX.db");

            // Path to the just created empty db
            String outFileName = "/data/data/XXX/databases/"
                    + "XXX.db";

            // Open the empty db as the output stream
            FileOutputStream myOutput = new FileOutputStream(outFileName);

            // transfer bytes from the inputfile to the outputfile
            byte[] buffer = new byte[1024];
            int length;
            while ((length = myInput.read(buffer)) > 0) {
                myOutput.write(buffer, 0, length);
            }

            myOutput.flush();
            myOutput.close();
            myInput.close();
            buffer = null;
            outFileName = null;
            this.dhn.close();
            this.dhn = null;
            this.dhn = DataHelper.getDataHelper(this); <<<<<<<< HERE IT CRUSHS
        } catch (IOException e1) {
            e1.printStackTrace();
