android - Notification Click not launch the given Activity on Nexus Phones

Question

I am using this code to show the local notification and When notification comes then on click of notification want to launch the ListActivity but on Google nexus device ListActiviy is not launches when click on notification, but on other device this code is working well.

    Intent notificationIntent = new Intent(context,
            ListActivity.class);
    notificationIntent.putExtra("clicked", "Notification Clicked");
    notificationIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |   Intent.FLAG_ACTIVITY_SINGLE_TOP);   // To open only one activity on launch.
    PendingIntent pIntent = PendingIntent.getActivity(context, reqCode,
            notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
    NotificationManager nM = (NotificationManager) context
            .getSystemService(Context.NOTIFICATION_SERVICE);
    NotificationCompat.Builder notify = new NotificationCompat.Builder(
            context);

    notify.setContentIntent(pIntent);
    notify.setSmallIcon(R.drawable.app_icon);
    notify.setContentTitle("Hello World");
    notify.setContentText("");
    notify.setAutoCancel(true);
    Uri alarmSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    notify.setSound(alarmSound);
    notify.setLights(Color.BLUE, 500, 1000);
    nM.notify(reqCode, notify.build());

Adding logcat when the activity is not launched:
