56,413 PointsUnfortunately the class name Callback
is a bit generic and many packages and libraries can have that class name. That means when you auto-import the class Android Studio may pick the wrong one like it did here. Luckily it's simple enough to fix.
// Change this line...
import javax.security.auth.callback.Callback;
// ...to this:
import okhttp3.Callback;
