SDK_INT >= android.os.Build.VERSION_CODES. O ) { int importance = NotificationManager. IMPORTANCE_HIGH ; NotificationChannel notificationChannel = new NotificationChannel( NOTIFICATION_CHANNEL_ID , "NOTIFICATION_CHANNEL_NAME" , importance) ; mBuilder.setChannelId( NOTIFICATION_CHANNEL_ID ) ; assert mNotificationManager != null; mNotificationManager.createNotificationChannel(notificationChannel) ; } assert mNotificationManager != null; mNotificationManager.notify(( int ) System. currentTimeMillis () , mBuilder.build()) ; } }
