NotificationCompat.Builder deprecated in Android O

by

It is mentioned in the documentation that the builder method NotificationCompat.Builder(Context context) has been deprecated. And we have to use the constructor which has the channelId parameter:

NotificationCompat.Builder(Context context, String channelId)

NotificationCompat.Builder Documentation:

This constructor was deprecated in API level 26.0.0-beta1. use
NotificationCompat.Builder(Context, String) instead. All posted
Notifications must specify a NotificationChannel Id.

Notification.Builder Documentation:

This constructor was deprecated in API level 26. use
Notification.Builder(Context, String) instead. All posted
Notifications must specify a NotificationChannel Id.

If you want to reuse the builder setters, you can create the builder with the channelId, and pass that builder to a helper method and set your preferred settings in that method.
