title: Second notification is not working
body: <p>I try to create multiple notifications. If click on the notification, it will link
  to another Activity. After following code, it's create two lines of notification.
  But when I click to the first line of notification, it's not working.
  Only second works.</p>
  
  <pre><code>for (int i = 0; i &lt; missionName.size(); i++) {
      mNotificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
      final Notification notifyDetails = new Notification(R.drawable.icon,
              "Mission Completed, Click Me!", System.currentTimeMillis());
      notifyDetails.defaults |= Notification.DEFAULT_SOUND;
      notifyDetails.defaults |= Notification.DEFAULT_VIBRATE;
      Context context = getApplicationContext();
      CharSequence contentTitle = missionName.get(i) + " is completed";
      CharSequence contentText = "Please click to view the mission";
      Intent notifyIntent = new Intent(getApplicationContext(),MissionMap.class);
      notifyIntent.putExtra("missionName", missionName.get(i));
      PendingIntent intent = PendingIntent.getActivity(ApplicationMenus.this,
              0, notifyIntent, android.content.Intent.FLAG_ACTIVITY_NEW_TASK);
  
      notifyDetails.setLatestEventInfo(context, contentTitle, contentText,
              intent);
      mNotificationManager.notify(i, notifyDetails);
  }
  </code></pre>
