If there are multiple launchers in a one package above code has a problem. Eg: on LG Optimus Facebook for LG, MySpace for LG, Twitter for LG contains in a one package name SNS and if you use above SNS will repeat. After hours of research I came with below code. Seems to work well.

private List getInstalledComponentList()
            throws NameNotFoundException {
        final Intent mainIntent = new Intent(Intent.ACTION_MAIN, null);
        mainIntent.addCategory(Intent.CATEGORY_LAUNCHER);
        List ril = getPackageManager().queryIntentActivities(mainIntent, 0);
        List componentList = new ArrayList();
        String name = null;

        for (ResolveInfo ri : ril) {
            if (ri.activityInfo != null) {
                Resources res = getPackageManager().getResourcesForApplication(ri.activityInfo.applicationInfo);
                if (ri.activityInfo.labelRes != 0) {
                    name = res.getString(ri.activityInfo.labelRes);
                } else {
                    name = ri.activityInfo.applicationInfo.loadLabel(
                            getPackageManager()).toString();
                }
                componentList.add(name);
            }
        }
        return componentList;
    }
