Answer 1

Documentation.

You specify the UI information and actions for a notification in a NotificationCompat.Builder object. To create the notification itself, you call NotificationCompat.Builder.build(), which returns a Notification object containing your specifications. To issue the notification, you pass the Notification object to the system by calling NotificationManager.notify()...

This is the code to put notification message in notification tray.100% working.

   NotificationManager notificationManager = (NotificationManager) 
                  getSystemService(NOTIFICATION_SERVICE); 

          Intent intent = new Intent(this, EndActivity.class);          
        PendingIntent pIntent = PendingIntent.getActivity(this, (int) System.currentTimeMillis(), intent, 0);

        // build notification
        // the addAction re-use the same intent to keep the example short
        Notification n  = new Notification.Builder(this)
                .setContentTitle("My message")
                .setContentText("Subject")
                .setSmallIcon(R.drawable.MyApplogo)
                .setContentIntent(pIntent)
                .setAutoCancel(true)
                .setStyle(new Notification.BigTextStyle().bigText(""+msg.get(3))).build();
              //  .addAction(R.drawable.line, "", pIntent).build();
        n.flags |= Notification.FLAG_AUTO_CANCEL;
         notificationManager.notify(0, n);
