Estou trabalhando no aplicativo Android onde estou usandosimonvt A biblioteca datepicker é compatível com versões anteriores, mas vejo no relatório de falha do console do desenvolvedor três relatórios para esse mesmo erro, mas tentei no meu dispositivo que está funcionando e isso é realmente estranho.

Por favor, apoiem isso porque é tão estranho e obtém exceção em algum momento.

OnDateSetListener date = new OnDateSetListener() {

    private void updateLabel() {

        String myFormat = "EEE, dd MMM"; // In which you need put here
        String myDbFormat = "dd/MM/yyyy";
        SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.US);
        SimpleDateFormat DBsdf = new SimpleDateFormat(myDbFormat, Locale.US);
        Departure_date = sdf.format(myCalendar.getTime());
        Departure_date_url = DBsdf.format(myCalendar.getTime());

        Log.i("Departure_date", Departure_date);
        date_btn.setText(sdf.format(myCalendar.getTime()));
    }

    @Override
    public void onDateSet(net.simonvt.datepicker.DatePicker view, int year,
            int monthOfYear, int dayOfMonth) {
        myCalendar.set(Calendar.YEAR, year);
        myCalendar.set(Calendar.MONTH, monthOfYear);
        myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
        updateLabel();
    }
};

Linha no: 703

final net.simonvt.datepicker.DatePickerDialog dpd = new net.simonvt.datepicker.DatePickerDialog(
                            getActivity(), date, myCalendar.get(Calendar.YEAR),
                            myCalendar.get(Calendar.MONTH), myCalendar
                                    .get(Calendar.DAY_OF_MONTH));
