I know than this bug was commented in other blogs but I've tried to correct this and I did not succeed.
Only happend in android 8+, but in simulator of Android Studio works fine.
I have an app than activate a notification in some specific date, this notification remember some task for user. This works fine in android 7 or lower but in Android 8+ don't works. App works fine, but notification don't appear and in google Play is activated an ERROR.
My app never crash, only shows that error into Google Play console.
This is the bug in PlayStore Console:

There are other java modules in my application, but the bug is in somewhere place of these code.
Thank you very much for your help, any hint and feedback is appreciated!.
