  NotificationManager notifManager = (NotificationManager) getActivity().getSystemService(Context.NOTIFICATION_SERVICE);
    Notification.InboxStyle inboxStyle = new Notification.InboxStyle();
    inboxStyle.setBigContentTitle("Title - Notification");
    inboxStyle.setSummaryText("TEST");
    inboxStyle.addLine("LINE");
    Notification noti = new Notification.Builder(getActivity())
            .setContentTitle("PSNGR")
            .setContentText("PITSTOP BLA").setSmallIcon(R.drawable.notification_icon)
            .setStyle(inboxStyle)
            .setContentIntent(null).build();

    noti.flags |= Notification.FLAG_AUTO_CANCEL;
    notifManager.notify(0, noti);

 NotificationManager notifManager = (NotificationManager) getActivity().getSystemService(Context.NOTIFICATION_SERVICE);
    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(getActivity())
            .setContentTitle("PSNGR")
            .setSmallIcon(R.drawable.ic_launcher)
            .setStyle(new NotificationCompat.BigTextStyle().bigText("MATA"))
            .setStyle(new NotificationCompat.BigTextStyle().bigText("MATA2"))
            .setAutoCancel(true)
            .setContentIntent(null);
    notifManager.notify(0, notificationBuilder.build());
