call the default home screen from application

I need to call the default home screen that comes with my phone from my application which is also a home screen app. I've tried searching and find this

    ArrayList<Intent> intentList = new ArrayList<Intent>();
    Intent intent=null;
    final PackageManager packageManager=getPackageManager();
    for(final ResolveInfo resolveInfo:packageManager.queryIntentActivities(new 
                  Intent(Intent.ACTION_MAIN).addCategory(Intent.CATEGORY_HOME), 
                                                        PackageManager.MATCH_DEFAULT_ONLY)) {
    intent=packageManager.getLaunchIntentForPackage(
                          resolveInfo.activityInfo.packageName);
    intentList.add(intent);
    }

this code is working for the all the other launchers but not for the default launcher. I tried using break points in code and found that at 0 index of list there should be default launcher intent but intent does'nt hold the value. Do I need some kind of permission thanks

you can just simple get the name and class from ResolveInfo and make intent manualy like for sonyercisson the package name is "com.sonyericsson.home" and class is "com.sonyericsson.home.HomeActivity" 

   Intent intent = new Intent();
   intent.setClassName("com.sonyericsson.home", "com.sonyericsson.home.HomeActivity");
   intent.addCategory(Intent.CATEGORY_LAUNCHER);
   startActivity(intent);

it works

Hope this will do.

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