.setSmallIcon(android.R.drawable.ic_dialog_alert)
.setLargeIcon(largeIcon)

.setWhen(System.currentTimeMillis())
.setStyle(new NotificationCompat.BigTextStyle().bigText(message));
Notification notification = builder.build();
NotificationManagerCompat notificationManager = NotificationManagerCompat.from(context);
notificationManager.notify(101, notification);
