Invalid Hijrah Day of Month : 31

I tried to create a simple activity with a button and a textview that showing the date. The button should show the HijriDatePicker dialog when clicked. I tried to make it using ummalqura-calendar and by the dialog, i tried use the HijriDatePicker to create the dialog.

However, after many attempts, it doesn't work. Sometimes the activity will stop when I click the button, and sometimes it just crash. I tried already for many fail attempts.

and my main activity java

public class MainActivity extends AppCompatActivity implements HijriDatePickerDialog.OnDateSetListener{
    TextView tvDate;
    TextView etDate;
    HijriDatePickerDialog.OnDateSetListener setListener;

    public MainActivity() {

    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        tvDate = findViewById(R.id.tv_date);
        etDate = findViewById(R.id.et_date);


        tvDate.setOnClickListener(v -> {
            UmmalquraCalendar now = new UmmalquraCalendar();
            HijriDatePickerDialog dpd = HijriDatePickerDialog.newInstance(
                    MainActivity.this,
                    now.get(Calendar.YEAR),
                    now.get(Calendar.MONTH),
                    now.get(Calendar.DAY_OF_MONTH)
            );
            dpd.setMinDate(new UmmalquraCalendar(1440,0,1));
            dpd.show(getSupportFragmentManager(), "Datepickerdialog");
        });

    }

    @Override
    public void onResume() {
        super.onResume();
        assert getFragmentManager() != null;
        HijriDatePickerDialog dpd = (HijriDatePickerDialog) getSupportFragmentManager().findFragmentByTag("Datepickerdialog");
        if (dpd != null) dpd.setOnDateSetListener(this);
    }

    @Override
    public void onDateSet(HijriDatePickerDialog view, int year, int monthOfYear, int dayOfMonth) {
        String date = "You picked the following date: " + dayOfMonth + "/" + (++monthOfYear) + "/" + year;
        System.out.println(date);
        etDate.setText(date);
    }
}

This problem seems to be a known bug in the msarhan-library. There was also a meanwhile closed issue on its related website. It indicates that a fix has been applied in the newest version.

So I suggest you to update your marhan library to version v2.0.2 which might solve your problem.

Update:

When looking at the date-picker-library you use we can see that it still uses the version v2.0.1. Either you wait until the author of the date-picker-library fixes the dependency or you build your own version of the date-picker-library.
