I want it work like it worked in android 10

One thing to note - "Mt manager" or "current Activity" etc apps are able to display the whole class names of app

Answer 1

It's my own question, so the problem is that code was(is) working fine for the purpose, but back then I relied on toast message for logging it worked in android 10 but in android 14, I guess toast message aren't displayed when application is minimised , afterwards I used Log for checking and found it that it is already working fine.

TL;DR - use Log instead of Toast
