How to block specific notifications from an app?

Question

A certain app I use gives me crucial notifications that I need, but also notifies me almost daily that over 80% of my RAM is used. I would like to allow this app to send me all notifications except those that contain the string "80% of your RAM" in the text of the notification.

Obviously, there is no way to filter a certain app's notifications in stock Android (other than blocking all of a certain app's notifications, but that's not what I want!), but is there a way that I can block notifications if they contain a certain string of text?

Nexus 6P running Android Marshmallow 6.0.1, if you're curious the app in question is CM Security.

Answer 1

I suggest you use MacroDroid or a similar app, such as Automate.

MacroDroid defines a set of trigger(s), action(s) and constraint(s) as a macro. You must enable Notification access permission and Usage Access permission in it.

You would be needing the following macro.

• Trigger: Notification → Notification Received:

  • From: choose your app
  • Text Content: here's where you can play. Choose Contains or Matches to filter your text specific notification.

• Action:

  • Clear Notifications → Select Application(s) → select your app → provide the filtering details again

• Constraints: none

Save the macro and you're good to go.

Note: MacroDroid can remove sticky/persistent notifications only in Android Oreo and above.
