回答1:

This is not a feature the of Android system. Device manufacturers (like Xiaomi you mentioned) or launcher developers (like Nova Launcher) can implement it and expose an api for app developers, but there is no standard for that, nor is it expected by the users to be there.

In general, you should not try to do this on Android.

For displaying badge, Google may have stopped showing numbers count on App Icon as a badge but I think it's still showing a dot to let the user know there is something new to that app.

For more information you can go through this official link from Google : https://developer.android.com/training/notify-user/badges
