NumberFormatException: Invalid int: "HH"

Question

I get the error Invalid int:"HH". It only occurs on some devices. I think the problem is in the conversion , but why does it work on most devices ?

This is the logcat:

java.lang.NumberFormatException: Invalid int: "HH"

                 }

Answer 1

Please use this -

String cdate = (String) DateFormat.format("hh:mm", c.getTime());

And for 24 Hour format please use this -

String cdate = (String) DateFormat.format("H:m", c.getTime());

instead of this-

String cdate = (String) DateFormat.format("HH:mm", c.getTime());

Answer 2

I think "HH" should be in small latter like

String cdate = (String) DateFormat.format("hh:mm", c.getTime());

Answer 4

According to doc, Up to API level 17, only adEhkMmszy were supported. Note that this class incorrectly implements k as if it were H for backwards compatibility.

Change 'HH' to 'kk', if you need 24 hour format. Remind that, 'H' refers hour in day (0-23), and 'k' refers hour in day (1-24)
