How to parse date "2022-07-18T08:24:18Z" in android

Question

I have tried these format but none worked.

yyyy-MM-dd'T'HH:mm:ss'Z'
yyyy-MM-dd'T'HH:mm:ssZ
yyyy-MM-dd'T'HH:mm:ssZZ
yyyy-MM-dd'T'HH:mm:ss

Also tried "ZonedDateTime", but it is not available below Android O.

@Ivo tried this too. But not working. In my case there is no "milisec" — Akanksha Paul, Aug 01 '22 at 11:16

If your minSDK is 25 or lower you have to use Java 8+ API desugaring support to be able to use the java.time package from Java 8.

With that enabled you can simply use e.g.

OffsetDateTime.parse("2022-07-18T08:24:18Z")
ZonedDateTime.parse("2022-07-18T08:24:18Z")

(you can find many resources about the differences of these date formats).

Or depending on what you need ot for: `Instant.parse("2022-07-18T08:24:18Z")`. – Ole V.V. Aug 01 '22 at 14:59

You can do it like this

fun parseDate(
        inputDateString: String?,
        inputDateFormat: SimpleDateFormat,
        outputDateFormat: SimpleDateFormat
    ): String? {
        var date: Date? = null
        var outputDateString: String? = null
        try {
            date = inputDateFormat.parse(inputDateString)
            outputDateString = outputDateFormat.format(date)
        } catch (e: ParseException) {
            e.printStackTrace()
        }
        return outputDateString
    }

inputString will be your Date, ex:"2022-07-18T08:24:18Z"
inputDateFormat : SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'", Locale.US)
outputDateFormat : in whichever format you want to show the date

I hope you get your answer from this

Already mentioned in question. This format is not working – Akanksha Paul Aug 01 '22 at 12:57
I tried and tested it. Use my parseDate method with it. – primo Aug 01 '22 at 13:10
Please don’t teach the young ones to use the long outdated and notoriously troublesome `SimpleDateFormat` class. At least not as the first option. And not without any reservation. We have so much better in [`java.time`, the modern Java date and time API,](https://docs.oracle.com/javase/tutorial/datetime/) and its `DateTimeFormatter`. Yes, you can use it on Android. For older Android look into [desugaring](https://developer.android.com/studio/write/java8-support-table). – Ole V.V. Aug 01 '22 at 15:14
I believe it will give 08:24:18 in my own time zone where 08:24:18 UTC was intended, so not correct (have not tested). – Ole V.V. Aug 03 '22 at 03:49
