Greylisted APIs are used by the runtime

I'm use NativeScript 6.2.0 with Android runtime 6.2.0. When i build my application and publish it Google Play Console, i get the following warnings from "Pre-launch report":

The following APIs are greylisted and Google can’t guarantee that they will work on existing versions of Android. Some may be already be restricted for your target SDK

I'm not sure if there is anything to worry about or if this can be safely ignored. The application seems to work fine though.
