I am trying to open a fragment when I press a notification in the notification bar. My app structure is:

* a base activity with a nav drawer menu
* some fragment that are opened from menu

```
b.setOnClickListener(new OnClickListener() {

        @SuppressWarnings({ "deprecation", "static-access" })
        public void onClick(View v) {

        w_nm=(NotificationManager) getActivity().getSystemService(getActivity().NOTIFICATION_SERVICE);

         Notification notify=new Notification(R.drawable.notnificationlogo,waternoti,System.currentTimeMillis());

         Intent notificationIntent = new Intent(getActivity(), Abc.class);

         PendingIntent pending=PendingIntent.getActivity(getActivity(), 0,notificationIntent, 0);

         notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
                 | Intent.FLAG_ACTIVITY_SINGLE_TOP );

        notify.flags = Notification.DEFAULT_LIGHTS | Notification.FLAG_AUTO_CANCEL;

           notify.setLatestEventInfo(getActivity(),waternoti,waternoti1, pending);

         w_nm.notify(0, notify);

```

Can anyone tell me how to link with next fragment page (the present code is in class that extends fragment)
