I have an error to save the validity of my package, I am passing the position of the array. What could be wrong?

  int position = 0;
  for (Pacote pacote: pacoteList) {
     Vigencia vigencia = new Vigencia();
     if (pacote.getVigencias().size() != 0) {
        Log.d("Vigencia", pacote.getVigencias().get(position).getMeses());

        vigencia.setMeses( pacote.getVigencias().get(pacoteList.indexOf(pacote)).getMeses());
        vigencia.setValorDescontoPromocional( pacote.getVigencias().get(pacoteList.indexOf(pacote)).getValorDescontoPromocional());
        vigenciaDao.inserirVigencia(db, vigencia, pacote.getCodigo());
     }

     position++;

  }

You are increasing the variable position each time it iterates through a package. In the third package this variable has value 2 (since it started in 0 ), only that the array of vigencias of the third package only has the indices 0 (first item) and 1 (second item), consequently you try to access an index that does not exist.
