My current project relies on catching notifications, and frequently stops catching notifications. I discovered that to restore the functionality, I need to disable then re-enable Notification Access in the system control panel, which seems to reset the "hook" and then new notifications are captured as expected.
I haven't figured out how to cause the listener to 'break' and haven't been able to catch the failure while connected to logging. But it happens so frequently I needed to add a test feature for the user to check if it is functioning (A button creates a notification and if the app doesn't capture it, then it leads the user to re-set Notification Access).
I suspect that the Notification Internal Service is crashing, failure seems to occur when a notification that is not even being processed by the app is received by the device, and is not restarting on it's own.
Is there a way to detect the running state and force a reset of the Notification Internal Service so I don't need to bother my users to do it manually?
Here is my Listener_NotificationPosted code, but it works fine, until something "un-hooks" the listener.
Thanks for looking.
