Hello again, I can’t answer (1) but I’ve just tried (2) on my machine and Android still appears in Project Settings when the phone isn’t plugged in. (It doesn’t however appear in the UE4 Launch menu).
Going back to (1) I don’t know what you have missed if anything?. So I would try is:
(1)… Have you installed the Android USB driver? If no, then install that.
(2)… I would (make sure your phone has development enabled) and then try plugging in your phone, before you run Unreal, that way it’ll make sure its detected.
(3)… also before you run Unreal, confirm its running with the Android tools first. You can try (4) to test it without unreal.
(4)… To make sure its detected, Goto C:\NVPACK\android-sdk-windows ools and then run monitor.bat in that directory.
At the bottom of the monitor on the left hand lower corner, there is a LogCat tab, select that and you should see debug messages coming from your phone.
If all of that works, then I don’t know what else to try?
I would say its best to confirm Android tools works (and your phone is in development mode) before you try it with Unreal. That’ll help narrow down what is going on?.
