Kotlin уведомляет и записывает звонок, когда вы его получаете ⇐ Android

[Anonymous]

I wrote the following code, when I receive a call I should receive a notification whether or not I want to record the call, the problem is that I do not receive any notification.

How do I ensure that the CallReceiver is always listening?

Furthermore, I don't need MainActivity to show anything, what can I do?

Can you give me a hand?

Manifest:

NotificationActionReceiver:
