I am having troubles with NotificationCompat v7 and Android O. Since the implementation of the NotificationCompatV7 only implements the deprecated constructor ( was deprecated in support library 26.0.0-beta1) of the v4 version, I am not able to get Notifications to work.
Solution for NotificationCompat v4 was proposed here: NotificationCompat with API 26
but since there is this issue with the poor implementation of the v7 version (https://issuetracker.google.com/issues/62475846) I am not able to post notifications on Android O
Does anybody have a solution for this or am I missing something here?
