Unable to send android notification using Notification manager

I am trying to send a notification using Notification builder class, but i am getting an error No Channel found.

Here is my code and error

Intent intent = new Intent(MainActivity.this,MainActivity.class);
                intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
                PendingIntent pendingIntent = PendingIntent.getActivity(MainActivity.this, 0, intent, PendingIntent.FLAG_IMMUTABLE);

                NotificationCompat.Builder builder = new NotificationCompat.Builder(MainActivity.this, "1")
                        .setSmallIcon(R.drawable.ic_launcher_foreground)
                        .setContentTitle("Title")
                        .setContentText("content")
                        .setStyle(new NotificationCompat.BigTextStyle()
                                .bigText("Much longer text that cannot fit one line..."))
                        .setPriority(NotificationCompat.PRIORITY_DEFAULT)
                        .setContentIntent(pendingIntent)
                        .setAutoCancel(true);
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
                    int importance = NotificationManager.IMPORTANCE_DEFAULT;
                    String description = "description";
                    CharSequence name = getString(R.string.channel_name);
                    NotificationChannel channel = new NotificationChannel("1", name, importance);
                    channel.setDescription(description);
                }


                NotificationManager notificationManager =
                        (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

                notificationManager.notify(1, builder.build());
