Androidドキュメントに書かれているとおり：

https://developer.Android.com/preview/features/notification-channels.html

Android Oをターゲットにし、有効な通知チャネルを指定せずに通知を投稿すると、通知は投稿に失敗し、システムはエラーを記録します。

この問題を解決するには、NotificationChannelを作成する必要があります。

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

// The id of the channel.
String id = "my_channel_01";

// The user-visible name of the channel.
CharSequence name = getString(R.string.channel_name);

// The user-visible description of the channel.
String description = getString(R.string.channel_description);

int importance = NotificationManager.IMPORTANCE_LOW;

NotificationChannel mChannel = new NotificationChannel(id, name,importance);

// Configure the notification channel.
mChannel.setDescription(description);

mChannel.enableLights(true);
// Sets the notification light color for notifications posted to this
// channel, if the device supports this feature.
mChannel.setLightColor(Color.RED);

mChannel.enableVibration(true);
mChannel.setVibrationPattern(new long[]{100, 200, 300, 400, 500, 400, 300, 200, 400});

mNotificationManager.createNotificationChannel(mChannel);

そして、次のように通知に割り当てます：

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

// Sets an ID for the notification, so it can be updated.
int notifyID = 1;

// The id of the channel.
String CHANNEL_ID = "my_channel_01";

// Create a notification and set the notification channel.
Notification notification = new Notification.Builder(MainActivity.this)
    .setContentTitle("New Message")
    .setContentText("You've received new messages.")
    .setSmallIcon(R.drawable.ic_notify_status)
    .setChannelId(CHANNEL_ID)
    .build();

// Issue the notification.
mNotificationManager.notify(id, notification);

更新：

NotificationCompatを使用する場合の簡単な例を次に示します。

NotificationCompat.Builder mBuilder;
mBuilder = new NotificationCompat.Builder(getApplicationContext())
    .setSmallIcon(R.mipmap.ic_launcher_icon)
    .setContentTitle("Title")
    .setContentText("Text")
    .setOngoing(true)
    .setChannelId(id);

実際、setChannelId（）を使用してチャンネルIDを設定するには、通知ビルダーを使用する必要があります。

ToastおよびLogcatのメッセージは、2つのアイテムに注意を払う必要があることを示しています。

  1. NotificationChannel mChannel = new NotificationChannel(id, name, importance);
  2. builder = new NotificationCompat.Builder(this, id);

また、NotificationManager notifManagerとNotificationChannel mChannelは一度だけ作成されます。

通知に必要なセッターがあります。

builder.setContentTitle() // required  
       .setSmallIcon()    // required 
       .setContentText()  // required

On Android 8.1 API 27通知が表示されない の例を参照してください。
