How to change the “Date” and “Time” of the mobile phone using “J2ME”?

Question

I'm developing a mobile application using "J2me" for a configuration "CLDC-MIDP2.0".

In my mobile application, I need to make the user should able to adjust the "Date" and "Time" settings of mobile.

Here I'm using "DateField" to get the date from the user, but I cannot set or change the mobile phone's "Date" and "Time".

How to change the "Date" and "Time" of the mobile phone using "J2ME"? Here I'm using "Nokia c2-00" mobile is for testing. It is "S40" device.

Answer 1

You can't do with Java ME. In Java ME, There are so many security features available. For example,

• You can't change the profile.
• You can't read the inbox/outbox SMS.
• You can't access the LOG.
• You can't change the date/time of the mobile.
• You can't change the mobile wallpaper/screen saver.

Answer 2

The answer can be found on this page at Nokia

Mobiles internal time cannot be changed by Java, because of security features which dont allow access to the native operations.
