Method available in android source code but not when coding?

Question

When I check the source code for WIFIP@PManager class https://android.googlesource.com/platform/frameworks/base/+/refs/heads/master/wifi/java/android/net/wifi/p2p/WifiP2pManager.java I see that there is a method setDeviceName but in my android code when I get WifiP2pManager wifip2pman = (WifiP2pManager)getActivity().getSystemService(Context.WIFI_P2P_SERVICE); wifip2pman doesn't provide the setDeviceName method!?!?

Answer 1

That method is marked with the @hide annotation, meaning that it is not part of the Android SDK.
