react native datepicker works only in debug mode

Question

I'm using native datepicker of android in react native app , only when I use debug mode I get date, but when I cancel debug mode using real phone I get in alert 'invalid date' in same date I choose with the debug.

  showDatePicker = async () => {
    if (Platform.OS === 'ios') {
        this.setState({ datePickerIosPlatform: true })
    } else {
        try {
            const { action, year, month, day } = await DatePickerAndroid.open({
                date: new Date()
            });
            if (action !== DatePickerAndroid.dismissedAction) {
               console.log('action', action, 'year', year, ' month', month, 'day', day)

                var stringDate = `${year} ${month} ${day}`;
                var newDate = new Date(stringDate)
                alert(newDate)

                var convertDate = moment(newDate).format('DD.MM.YYYY') 
                console.log('convertdata',convertDate)

                // this.convertDate(stringDate)
            }
        } catch ({ code, message }) {
            console.warn('Cannot open date picker', message);
        }
    }

}

you can change this string `${year} ${month} ${day}` to `${year}/${month}/${day}` so it will not say 'invalid date' again — bun houth, Jul 08 '18 at 18:31
I think for android when the format doesn't have dash or slash it doesn't work. However, when the format is set to "YY-MM-DD" or "YY/MM/DD", it will work. — Sandy....., Jul 08 '18 at 19:33

Today I had a similar issue (and solved it!).

I've tried to generate an Date-Object of an given String (German Date Format) new Date("06.06.2020"). After that, I've tried to compare the generated Date with today new Date().

As it worked well on Debug-Mode, it doesn't work on a bundled Release APK. I got invalid Date-Message even like you.

Solution

I've figured out, that you must have an full qualified ISO_8601 formatted string to generate an date.

So I did the following to convert my date in that ISO_8601 formatted:

const startNextFestival = "06.10.2020".split('.').reverse().join('-')+"T10:00:00.000Z";
const nextFestival = new Date(startNextFestival);

This generates following Date-String for startNextFestival: "2020-06-06T10:00:00.000Z" This way it works like a charm, to generate.

Hope that's helps somebody.
