can not launch home from android 4.0

 

Questions


I want to launch Home Screen From my application for that I used

Intent intent = new Intent(Intent.ACTION_MAIN);
                intent.addCategory(Intent.CATEGORY_HOME);
        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        startActivity(intent);

I also follow this thread
Now I am having problem to launch in ICS(4.0). Problem is that I can’t launch home screen while I am in some other application(to check this I created a thread in my app which will sleep for 5 sec and fires the intent so that I get time to go in some other app) it is working fine in 2.2 but failing on 4.0

Is this because of new architecture and way of handling activities in 4.0?

Logs are
