              DatePickerDialog dpd = new DatePickerDialog(this,
                      new DatePickerDialog.OnDateSetListener() {
  
                          @Override
                          public void onDateSet(DatePicker view, int year,
                                                int monthOfYear, int dayOfMonth) {
                              arivalDay = year;
                              arivalYear = monthOfYear;
                              arivalMonth = dayOfMonth;
  
                              arivalDateTV.setText(dayOfMonth + "-"
                                      + (monthOfYear + 1) + "-" + year);
  
                          }
                      }, arivalYear, arivalMonth, arivalDay);
              dpd.getDatePicker().setMinDate(System.currentTimeMillis() - 1000);
              dpd.show();

  <p>Here is my departure date picker</p>
  
  <pre><code>DatePickerDialog dpd = new DatePickerDialog(this,
                      new DatePickerDialog.OnDateSetListener() {
  
                          @Override
                          public void onDateSet(DatePicker view, int year,
                                                int monthOfYear, int dayOfMonth) {
                              departureYear = year;
                              departureMonth = monthOfYear;
                              departureDay = dayOfMonth;
  
                              departureDateTV.setText(dayOfMonth + "-"
                                      + (monthOfYear + 1) + "-" + year);
  
                          }
                      }, arivalYear, arivalMonth, arivalDay);
              Date min = new Date();
              min.setDate(arivalDay);
              min.setMonth(arivalMonth);
              min.setYear(arivalYear);
  
              dpd.getDatePicker().setMinDate(min.getDate());
              dpd.show();
  </code></pre>
