<need help>import android.annotation.UnsupportedAppUsage can not be invoked...

[heatonJr]

Hello,
I downloaded android-hidden-api/android-28/android.jar, and replaced what default in my project.
some classes can be invoked, e.g. android.annotation.MainThread, Nullable, WorkerThread...
but android.annotation.UnsupportedAppUsage still can not be invoked,

Could you help me to deal with this issue?
Thanks ...

that annotation has no real effect on Android Studio, you can add the same full qualified named empty annotation to your code.
