Answer 1

So that the notification does not launch any Activity(Intent) when clicked create the Pendigintent, passed to the method setContentIntent() of Notificationcompat.Builder, as follows:

PendingIntent resultPendingIntent = PendingIntent.getActivity(context,  0, new Intent(), 0);

Replace the 0 the values you want to use. The important thing is to pass new Intent() in the third parameter.

To delete notification when clicked use setAutoCancel(true) when building the notification.

Create the notification:

private void sendNotification() {
    NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
    builder.setSmallIcon(R.drawable.ic_stat_name);
    builder.setContentTitle("My title");
    builder.setContentText("Content Text");
    Intent removeNotifivationIntent = new Intent();
    removeNotifivationIntent.setAction(REMOVE_NOTIFICATION);
    PendingIntent removeNotifivationPendingIntent = PendingIntent.getBroadcast(this, 0, removeNotifivationIntent, 0);
    builder.setContentIntent(removeNotifivationPendingIntent);
    NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
    notificationManager.notify(NOTIFICATION_ID, builder.build());
}

Create a Broadcastreceiver, can be in Oncreate:

    receiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            String action = intent.getAction();
            if (REMOVE_NOTIFICATION.equals(action)) {
                String ns = Context.NOTIFICATION_SERVICE;
                NotificationManager nMgr = (NotificationManager) getApplicationContext().getSystemService(ns);
                nMgr.cancel(NOTIFICATION_ID);
            }
        }
    };
    registerReceiver(receiver, filter);
