The Guardian app is nice. It has an internal interface. You can set it to focus on USA or on International news. You can pick what categories of news are of interest to you. It has has breaking news notifications.
Here's my hypothesis: the Guardian app. (https://play.google.com/store/apps/details?id=com.guardian)
It has the right sort of visual styling and was showing up in Running Services. I've uninstalled it and haven't seen the toast show up again yet. I'll update this reply if it turns out not to be the solution.
Ich benutze die app vom guardian oder einfach reddit..
