Create a PendingIntent for Notification to do nothing

Refer to the last post "error of using NotificationCompat.Builder, IllegalArgumentException: contentIntent required", if you want no action perform when user click on the Notification, you can insert a PendingIntent with a dummy Intent.

Example:

    PendingIntent pendingIntent = PendingIntent.getActivity(
      MainActivity.this, 
      0, 
      new Intent(),  //Dummy Intent do nothing 
      Intent.FLAG_ACTIVITY_NEW_TASK);
      
    myNotification = new NotificationCompat.Builder(context)
          .setContentTitle("Exercise of Notification!")
          .setContentText("http://android-er.blogspot.com/")
          .setTicker("Notification!")
          .setWhen(System.currentTimeMillis())
          .setContentIntent(pendingIntent)
          .setDefaults(Notification.DEFAULT_SOUND)
          .setAutoCancel(true)
          .setSmallIcon(R.drawable.ic_launcher)
          .build();
