Android 7.0, NotificationListenerService is no longer working

Hello
"I made my own class ""NotificationLiseter(*1)"" and it was working until recently, but before I knew it, it stopped working."For example, switching Notification access does not refer to onListenerConnected().
"Once I made a ""NLStest(*2)"" that does nothing and made sure it worked properly, I copied it to (*1), but it didn't work."
I checked the Manifest by changing it thoroughly.

Why doesn't (*1) work?

Tried

Rebuild the project
Make sure to create another NotificationListener and work
Toggle Notification access.The NLStest was switched properly.

I just started developing Android, so I think there are some things that I can't do, but I appreciate your cooperation.

Why don't you try the following solutions from your home?

https://stackoverflow.com/questions/33530807/why-is-this-notificationlistenerservice-not-working

It may not work due to cache problems.

About its NotificationLiseter on Android Studio
From the menu, under Refactor->Rename, click
Change to the appropriate name (for example, NotificationLiseter2).I'm sorry)
See if it works.

I have also confirmed that it works with rename.
