Android permissions, "Never ask again" dilema

Question

So, this is what I want to achieve:

user taps button A, if the permission is not in "never ask again" state, ask it directly:

-> if granted, perfect

-> if denied, do nothing, user taps again, and same thing reproduces. if "never ask again" was checked, then show a popup to redirect to settings.

now I know I can use the shouldShowRequestPermissionRationale when it is denied. but here's my problem:

1. user denies with "never ask again" checked
2. I get a permission denied
3. I check on shouldShowRequestPermissionRationale, I find it false and I know that it was permanently denied, I save it to cache.
4. I want to ask for the permission again.
5. I read from cache that I can't do it.
6. show a popup to redirect to settings.
7. user enables + disables the same permission.
8. user goes back to the app.
9. I want to ask for the permission again.

BOOM: if I rely on the cache, I would think the permission is permanently disabled, whereas if I directly ask for it, the system will show the permission popup with "deny" "accept".

How can I go around that, and more importantly, why is there nothing on the public API to know without any headache if a certain permission is in "never ask again" mode.

Thank you all
