How to receive time format changed 12 to 24 vice versa from native device settings?

Question

I have a requirement to update the current time in my application as per device time format(12/24). I need any callback/listeners/receivers which will let me know that time format has been changed so that i can update time in my application accordingly.

I got the way to get current timeformat using below code snippet

String value = android.provider.Settings.System.getString(this.getContentResolver(), android.provider.Settings.System.TIME_12_24);

But looking for any callback which will let me know the same in run time.

Thanks in advance.

i think you dint get my question .. i asked for any call back or receiver which will let me know if format is changed. — Daud Arfin, Jul 18 '14 at 09:35
@Sreekanth there is no separate filter for time format but timeset filter is working for time format also. — Daud Arfin, Jul 18 '14 at 10:11

android.text.format.DateFormat.is24HourFormat(Context context); Use this function to get the time format. Register a Broadcast receiver which listens to ACTION_TIMEZONE_CHANGED,ACTION_TIME_CHANGED,ACTION_TIME_TICK.

Something like this,

IntentFilter intentFilter=new IntentFilter();
intentFilter.addAction(Intent.ACTION_TIME_TICK);
intentFilter.addAction(Intent.ACTION_TIMEZONE_CHANGED);
intentFilter.addAction(Intent.ACTION_TIME_CHANGED);
registerReceiver(youReciverHere,intentFilter);

Do work on the receiver s onReceive() function.
