Probably. I have been able to build to Android with 4.17.2 using only blueprints,
and succeeded in both hosting as server and joining as client over Wifi LAN, using the Android.
I have only one Android device with enough RAM to handle Unreal engine, so the other player was a PC but it worked both when Android was the server and when Android was the client!
And I didn’t have to do anything special or different. The code for PC worked just as well for Android (except I needed to add touch controls for input). Android is mobile with a lower power processor than the PC so some optimizations were needed for performance. But as for the networking, no difference in the blueprint code.
