Android DateFormat for AM/PM differs between devices

Question

I am formatting dates like this:

    public static String toFormattedDate(@NonNull Time time, String toFormat) {
        mDateFormat = new SimpleDateFormat(toFormat);

        Date date = new Date();
        date.setTime(time.toMillis(true));

        return mDateFormat.format(date);
    }

and the format I am using is:

    public static final String TIME = "hh:mm a";

But it differs between the two devices that I am using for testing...

Nexus 10:

Nexus 5X:

How can I format it uniformly between devices?

Answer 1

You may either have to use either the 24 hour value to determine what to append so that you can add the format you desire.

public static final String TIME = "hh:mm";

and then

String ampm = Integer.parseInt(time.valueOf("hh")) >= 12 ? "PM" : "AM";
...
return mDateFormat.format(date)+" "+ampm;

Or if you feel lazy you can just do without changing the value of TIME:

return mDateFormat.format(date).toUpperCase().replace(".","");
