Wrong Date Format shown in device from JSON API

Question

I was showing my JSON date in activity layout but it gives me this kind of date format "1547458358000". How to change the date format into YYYY-MM-dd k:mm:s?

The appAdded is date came from JSON API.

From the result of testing. The toast message I received is API TIME shows as 1547458358000 while outDatedAPI shown as null.

 try {
    SimpleDateFormat DateformatAPKAPIInstalled = new SimpleDateFormat("YYYY-MM-dd k:mm:s");
        APITime = DateformatAPKAPIInstalled.parse(appAdded);
        SimpleDateFormat outputFormat = new SimpleDateFormat("YYYY-MM-dd k:mm:s");
         outputDateAPI = outputFormat.format(APITime);
        Toast.makeText(FirstPageActivity.this, "DATE KO" dateAPKUpdated + appAdded + APITime, Toast.LENGTH_LONG).show();


    } catch (ParseException e) {
        e.printStackTrace();
    }

that is timestamp you need to convert it to appropriate date. — karan, Jan 24 '19 at 06:46

"1547458358000" seems to be the milliseconds since midnight on 1 Jan 1970. — Henry, Jan 24 '19 at 06:47
Do a google search for converting time stamp to date for the enlightment — Vivek Mishra, Jan 24 '19 at 06:51
As an aside consider throwing away the long outmoded and notoriously troublesome `SimpleDateFormat` and friends, and adding [ThreeTenABP](https://github.com/JakeWharton/ThreeTenABP) to your Android project in order to use `java.time`, the modern Java date and time API. It is so much nicer to work with. — Ole V.V., Jan 25 '19 at 11:37

You can pass long timestamp and can convert it to date using below code

private String getDate(long time) {
    Calendar cal = Calendar.getInstance(Locale.ENGLISH);
    cal.setTimeInMillis(time);
    String date = DateFormat.format("yyyy-MM-dd", cal).toString();
    return date;
}
