App won't be shown in app permissions using NotificationListener

Hello, I'm not being able to find my app in the "Notification Permission" menu on my phone.
I have a Galaxy S8 with Android 9, your example app works perfectly but when I try using your extension in my app it won't be shown in the list and the service doesn't start. I share here the png of blocks

what happens, if you try the example app downloadable from here


Trying to push the limits! Snippets, Tutorials and Extensions from Pura Vida Apps by icon24 Taifun.

I've solved the problem, while replicating the code I forgot to insert a TinyDB command, by inserting it my app is now showing in the list. Thanks still for your reply!

@Taifun Sorry for bothering again.
System works, but I now need to understand something : is there a way to convert json notification into Text of appinventor? because I need to work on TEXT string and not json string..

I'm having the same problem as that of @AvengerScarlet. I am on a Oneplus Nord CEm and the companion is not in the notification permission list. Even with the exact code as in your example project.

From the documentation

Note: You will have to build the app to be able to receive the notifications.


Thank you. I should have thought of that!
