Android O requires that you specify a channel when sending a message. If you don't, it pops up the following message every time it receives one:
Developer warning for package "com.foo"
Failed to post notification on channel "null"
When I'm sending a notification to an Android device using Azure NotificationHub, how do I specify the channel?

Hi Steve,Are you using Firebase Cloud Messaging or Google Cloud Messaging for your notification messages? You can also take a look at this SO thread. It looks like its a similar issue.
