Android R new Api isAutoRevokeWhitelisted() 即使手动打开/关闭权限重置也总是给出 false

Question

So on Android R, user can now choose to allow the OSs to revoke given permission if the app isn't using them. This new settings will be available in the permission section of the app setting(check screenshot for reference), by default its turned off as per current beta behaviour

https://developer.android.com/preview/privacy/permissions#auto-reset

There is an api added to track if currently your app is in the given whitelist or not

https://developer.android.com/reference/android/content/pm/PackageManager#isAutoRevokeWhitelisted() . I tried testing this but even when i turn the on or off the settings the api always returns false. Wondering if anyone else has faced this issue yet.

I checked the logs and i can see a few logs which makes me feels that even after turning the option on its doesnt actually get added to the whitelist

You probably have targetSDK set to 29, I also experienced incorrect API work on it. But if I set targetSDK to 30 it gets back to normal.
