[FIXED] How to get the timezone offset in GMT(Like GMT+7:00) from android device?

Issue

I am getting the timezone of a android device using this code

TimeZone tz = TimeZone.getDefault();
String current_Time_Zone = (TimeZone.getTimeZone(tz.getID()).getDisplayName(
                false, TimeZone.SHORT))

But it always return me the timezone like "IST" but i want to get the timezone in GMT like this GMT+7:00.

Solution

This code return me GMT offset.

Calendar calendar = Calendar.getInstance(TimeZone.getTimeZone("GMT"),
                Locale.getDefault());
Date currentLocalTime = calendar.getTime();
DateFormat date = new SimpleDateFormat("Z");
String localTime = date.format(currentLocalTime);

It returns the time zone offset like this: +0530

If we use SimpleDateFormat below

DateFormat date = new SimpleDateFormat("z",Locale.getDefault());
String localTime = date.format(currentLocalTime);

It returns the time zone offset like this: GMT+05:30
