How to access notification channels for another Android app?

Question

I want to create a function that calls the notification channel settings for another app. I don't know the channel IDs for the other app. Is there a way to do that?

Answer 1

You cannot access the notification channels of another app, neither what channels there are nor what their settings are.

The only thing you can do is to open the notification settings overview of another app, given its package name (Facebook for example):

Intent intent = new Intent(Settings.ACTION_APP_NOTIFICATION_SETTINGS)
        .putExtra(Settings.EXTRA_APP_PACKAGE, "com.facebook.katana");
startActivity(intent);
