Unsupported API's in google play 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.
Kindly help me to resolve this warning. Thanks in advance.

Good question, I get similar warnings.
To clarify: the warnings appear in the pre-launch report that Google generated after I published an update of a test version of my app. When building the app in Android Studio no warnings were generated.

Any solution to get rid of these warnings, thanks
